The Toyota Land Cruiser is a series of four-wheel drive vehicles fashioned by the Japanese car maker Toyota Motor Corporation. Programming of the first generation secure Cruiser began in 1951 as Toyota's type of a Jeep-like vehicle and production started in 1954. The secure Cruiser happens to be released in convertible, hardtop, station wagon, and utility truck versions, and it is currently Toyota's flagship 4WD vehicle. The Land Cruiser's excellence and longevity has led to huge popularity, exclusively in Australia where it is the best-selling full-size, body-on-frame, four-wheel drive vehicle.Toyota also extensively tests the Land Cruiser in the Australian outbackÃ�ÃÂÃÂÃÂÂÃÂÃÂÃÂÃÂconsidered to be one of the most challenging running environments with regards to of both environment and terrain. 40 Series 40 Series Toyota Secure Cruiser (BJ40LV) Also called Toyota Macho (Venezuela) Production 1960-1984 Assembly ARACO Yoshiwara,Aichi, Japan Body style(s) 2-door Softtop 2-door Hardtop 2-door pickup truck 4-door Station wagon Layout FR layout Engine(s) 3.0 L I4 B diesel 3.9 L I6 F petrol 4.2 L I6 2F petrol 3.6 L I6 H diesel Wheelbase 90 in (2286 mm) Size 151.2 in (3840.5 mm) Width 65.6 in (1666.2 mm) Height Softtop 76.8 in (1950.7 mm) Hardtop 78.8 in (2001.5 mm) Curb weight Softtop 3,263 lb (1,480 kg) Hardtop 3,427 lb (1,554 kg) * 1960 - The 20 Series was upgraded to the now classic 40. Toyota created numerous production changes by buying new steel presses. Automatically, the FJ40 was given a unique 125 hp, 3.9 liter F motor and the Land Cruiser finally received low-range gearing. The Brazilian unit had been rebadged the Bandeirante and received a Mercedes-Benz built Diesel engine generating 78 hp. * 1965 - Global production surpassed 50,000 vehicles. The Land Cruiser was the better selling Toyota in the United States Of America. * 1968 - The 100,000th secure Cruiser had been sold worldwide. * 1972 - The 200,000th Land Cruiser was sold globally. * 1973 - The 300,000th Land Cruiser was sold around the world. The starting diesel Land Cruiser was introduced for export on long wheelbase models with a six-cylinder H engine * 1974 - A four-cylinder 3.0-liter c diesel was offered. The introduction of this engine doubled sales in Japan by putting the Land Cruiser in a lower tax compact Freight-car market than the 3.9-liter gasoline version. Note: the brand-new B diesel system was many from the B gasoline engine used within the original BJ. * 1975 - The 3.9-liter gasoline engine was replaced by a bigger, more powerful 4.2-liter 2F unit. The FJ55 was given front disc brake system. * 1976 - United States-version FJ40 Land Cruisers was given front disk brake system like the FJ55. The Toyota Land Cruiser Association had been started in California. * 1977 - The Irish Army took delivery of the first of 77 FJ45 Land Cruisers. Although fast, legitimate and with good off-road performance the nature tended to rust excessively in the wet Irish climate. A few which did not yield to the benefits of weather were repainted in gloss olive green and survive as ceremonial gun tractors at military funerals. * 1978 - The starting BJ / FJ40 and FJ55 models were officially available in West Germany with both diesel (BJ40) and petrol engines (FJ40 /55). * 1979 - United States-version FJ40s were updated this year with a new wider, square bezel surrounding the headlights. Energy steering and cooler were offered in FJ40s for the first occasion. The diesel engine was improved, evolving into the 3.2-liter 2B exclusive in Japan. The 3.6-liter H diesel engine had been optional in some markets. * 1981 - the Diesel adaptation received front disk brakes and the a bit more powerful 3.4-liter 3B engine. 50 Series 50 Show Toyota Land Cruiser (FJ55LG) Manufacturing 1967-1980 Assembly ARACO Yoshiwara, Aichi, Japan Body style(s) 4-door station wagon Layout Front engine four-wheel drive Engine(s) 3.9 L I6 F petrol 4.2 L I6 2F petrol Transmission(s) 3 or 4-speed handbook (J30, H41 or H42) Wheelbase 2,710 mm (106.7 in) Length 4,673 mm (184.0 in) Width 1,710 mm (67.3 in) Height 1,864 mm (73.4 in) * 1967 - manufacturing of the FJ55 began. The FJ55 was a 4-door station wagon version based on the FJ40's Drive-train, replacing the 4-Door FJ45V (I). It was colloquially known as the "Moose". It offers also been referred to as a pig or an iron pig. The FJ55 had a more wheelbase 2710 mm and was designed to be available in North The usa and Australia. * Jan 1975 saw the F system changed by the 2F engine. Unusually for Toyota, the model (e.g. FJ55) decided not to change. * Unit 56 is actually in Japan merely, with 2F system ( Jan. 1975 - Jul. 1980 ). 60 Series 60 Series Toyota Secure Cruiser (FJ62LG) Also called Toyota Samurai (Venezuela) Production 1980-1990 Assembly ARACO Yoshiwara, Aichi, Japan Body style(s) 4-door station wagon Layout Front engine, four-wheel drive Engine(s) 3.4 L I4 3B diesel 3.4 L I4 13B-T diesel turbo 4.2 L I6 2F petrol 4.0 L I6 3F petrol 4.0 L I6 2H diesel 4.0 L I6 12H-T diesel turbo 4.2 L I6 1HZ diesel 4.2 L I6 1HD-T diesel turbo Transmission(s) 4-speed handbook H41F or H42F 4-speed automatic A440F 5-speed manual H55F (non-US) Wheelbase 2,730 mm (107.5 in) Length 4,675 mm (184.1 in) Width 1,800 mm (70.9 in) Elevation 1,750 mm (68.9 in) The initial Toyota Land Cruiser FJ 60 was available for purchase from 1981 through 1987. It is actually a front system four door wagon which has available seating of five to seven. It is well known in the off-roading community for its tremendous 4X4 capabilities, despite being somewhat limited by its poor departure angle. The FJ 60 had been offered within the following sturdy outside colors: mountain White, Brown, Desert Beige, Freeborn Red, Royal Blue; and in the following metallic outdoor colors: Charcoal Gray, Cognac, Gray-Blue, Rootbeer, Sky Blue, Stardust Silver. In compare to the FJ 62, the FJ 60 exhibits the classic round secure Cruiser headlights which are really replicated nowadays on the retro-style FJ Cruiser. * 1980 - The 60 series was introduced. While still retaining the tough off-road characteristics of previous Land Cruisers, the 60 had been created to better compete in the promising sport utility vehicle market. The 60 had been given a variety of luxuries like air conditioning, a back heater and an upgraded interior. The FJ60's "2F" petrol engine had been left unchanged from the "40" show while six-cylinder 4.0 litre 2H and four-cylinder 3.4 litre 3B diesel engines were added to the item line. * 1981 - secure Cruiser sales exceeded 1 million and a high-roof version had been introduced. The 60 had been introduced to South Africa when a stock secure Cruiser competed in the Toyota 1000 km Desert run within the punishing wilds of Botswana. * 1984 - This was the final 12 months for the 40. Specialist suppliers of aftermarket parts and restorers who return familiar FJ40s to better-than-new state replace Toyota dealers as the main source of Land Cruiser expertise. * 1984 - Alongside the 60, the Toyota Land Cruiser 70 Series were introduced. * 1985 - The Direct-injection 12H-T and 13B-T turbodiesel system were introduced. * 1988 - The petrol engine had been improved to a 4.0-litre 3F-E EFI engine. The FJ62G VX-Series had been introduced creating the Land Cruiser to feel sold in Japan as a passenger vehicle. * 1990 - The 80 show station wagon had been introduced, replacing the 60. The 80 had been originally offered with a solution of three engines; the 3F-E six-cylinder petrol system, a six-cylinder the 1HZ diesel and 1HD-T direct shot turbodiesel. * 1990 - All 80s sold in North America and Europe nowadays produce a full-time four-wheel drive system. In Japan, Africa and Australia, a part-time system was still available. 80s produced between 1990 and 1991 had an open centre differential which was lockable in 4HI and automatically locked in 4LO. From 1992 onward, vehicles with anti-lock brakes had a viscous coupling that sent a maximum of 30% torque to the non-slipping axle. The differential was lockable in 4HI and automatically locked in 4LO.

- Use eye protection; be careful of sharp sheet metal and plastic edges behind dash.
- Label all electrical connectors, screws, and ducts you remove.
- Avoid cigarette ash or open flame near spilled coolant.

Overview (what you’ll do)
1. Drain or lower coolant level and disconnect heater hoses at the firewall/engine bay.
2. Remove dash trim, glovebox, and HVAC ducting needed to access heater core housing.
3. Disconnect electrical connectors and vacuum lines attached to housing and HVAC controls.
4. Unbolt and open heater core housing, remove old heater core and seals.
5. Install new heater core and seals, reassemble housing and dash in reverse order.
6. Reconnect hoses, refill and bleed coolant, test for leaks and heater operation.

Step‑by‑step procedure (general Toyota chassis/body — adapt to model)
1) Preparation
- Park on level ground, set parking brake. Allow engine to cool.
- Disconnect negative battery terminal.
- Place drain pan under radiator petcock; open petcock and drain enough coolant to lower level below heater hose connection or completely drain (recommended: drain to avoid spills when hoses are disconnected).
- Remove any engine bay components blocking access to the two heater hoses at the firewall (air cleaner intake, battery hold down, covers). Label inlet/outlet hoses (left/right or inlet/outlet).

2) Disconnect heater hoses
- Use hose clamp pliers or screwdriver (worm clamp) to loosen clamps.
- If Toyota uses quick‑connect fittings, use the appropriate line disconnect tool: push tool into fitting to release retaining tab while pulling hose off. Protect paint and firewall surfaces; keep pan under connection to catch residual coolant.
- Cap hoses temporarily or plug heater hose ends to minimize coolant loss.

3) Interior access & dash trim removal
- Remove glovebox (open, depress stops and pull). Remove lower dash panels and knee bolster using Torx/Phillips/10 mm as required.
- Use trim tools to pop off panels without breaking clips. Keep fasteners organized and labeled.
- Remove center console or parts of it if necessary (gear selector trim, ashtray, cupholders) — depends on model.
- Disconnect and support the steering column lower cover if it obstructs access.
- Remove passenger side lower dash support and the HVAC ducting (large plastic ducts leading to footwell and defroster).

4) Remove HVAC housing covers and locate heater core
- Remove screws/bolts holding HVAC housing halves (usually 8–12 mm or Torx). Remove retaining clips.
- Carefully separate housing halves to expose heater core; foam seals and clips may be brittle—pry gently with plastic tools.
- Be prepared for residual coolant to spill from the core; keep drain pan and rags ready.

5) Disconnect electrical/vacuum connections and remove heater core
- Disconnect blend door actuator connectors and any sensors on the housing (label connectors).
- Remove any metal heater pipe brackets or clamp bolts securing heater core lines inside the passenger compartment.
- Slide out the heater core from its seat. Note orientation and seal placement. Inspect foam gaskets and replace if damaged.

6) Install new heater core and seals
- Compare old and new cores to ensure correct fit and hose fitting orientation.
- Install new foam gaskets/seals around core mounting; use new O‑rings or quick‑connect seals on the heater hose fittings as required.
- Slide heater core into housing correctly so internal fins and pipes seat without stress. Make sure seals are flush to prevent air/coolant leaks.

7) Reassemble HVAC housing & interior (reverse disassembly)
- Reconnect actuators, sensors and vacuum lines. Ensure blend doors operate freely; don’t pinch actuator harnesses.
- Refasten housing halves to correct torque (snug; do not overtighten plastic screws).
- Reinstall ducts, glovebox, and trim panels. Reattach steering column covers and console pieces. Replace any broken clips with new ones.

8) Reconnect heater hoses & refill coolant
- From engine bay, reconnect heater hoses to the firewall pipes. Use new O‑rings/quick-connect seals or new hose clamps.
- Tighten clamps securely; avoid overtightening worm clamps to the plastic nipples.
- Refill cooling system with the correct coolant to the recommended level. Use a funnel and degassed coolant if possible.

9) Bleed/burp cooling system
- With radiator cap off (or bleeder valve open if equipped) start the engine and let idle with heater on high and blower on (max) to circulate coolant through heater core and purge air.
- Squeeze heater hoses to help dislodge trapped air. Top up coolant as level drops.
- If vehicle has bleed screws, open them until a steady stream of coolant flows, then close.
- Once thermostat opens and system is at normal operating temp, check for bubbles; repeat until no air remains. Replace radiator cap.

10) Final checks
- Verify heater delivers hot air at dash vents.
- Inspect all connections and housing for leaks with engine at operating temp and under light revs.
- Road test and re‑check coolant level after cool down; top off as needed.
- Recycle old coolant and dispose of replaced parts per regulations.

Tool usage details
- Trim tools: wedge between panel and body, pry gently to release plastic retaining clips without scratching trim.
- Torx/Socket with extensions & swivel: reach recessed bolts in housing and under dash. Use swivel to access tight angles.
- Hose clamp pliers: compress spring‑type clamps and slide back along hose to free; release slowly to avoid clamp snapping.
- Quick‑disconnect tool: push straight into the fitting until it clicks, then pull the hose off by hand. Practice on a spare fitting if unfamiliar.
- Magnetic tray and labeled bags: put fasteners from each step together and label to speed reassembly and avoid missing screws.
- Torque wrench: tighten metal bolts to manufacturer spec where possible; for plastic bolts, snug to feel to avoid stripping.

Common pitfalls & how to avoid them
- Breaking plastic HVAC housing or clips: pry gently, use proper trim tools, replace brittle clips before reassembly.
- Reusing old O‑rings/seals: they harden and leak — always replace seals on heater pipes and hose ends.
- Not bleeding the system properly: causes air pockets, poor heater performance, and overheating. Use heater on high while bleeding; open bleeder screws if provided.
- Mixing up hose orientation: mark inlet/outlet before removal; improper connection may not damage engine but can change flow characteristics and cause poor heating.
- Overlooking small connections: vacuum lines or actuator connectors left off can cause incorrect HVAC operation.
- Damaging heater core fins or tubes: handle core by tank/pipe areas, not by fins.
- Reusing contaminated coolant: flush system if old coolant is dirty or if heater core failed due to corrosion/debris.
- Forgetting to reconnect battery: may prevent actuators/self‑test from functioning; reconnect only after most dash work is complete.
- Tightening metal hose clamps too much: can crack plastic nipples. Tighten snugly but not excessive.

Replacement parts recommended
- Heater core (vehicle-specific).
- Heater hoses or at least new hose clamps and new O‑rings/quick‑connect seals.
- HVAC housing foam seals/gaskets (often available in kits).
- Cabin air filter (good time to replace).
- Any broken dash/clips removed during disassembly.
- Fresh coolant (correct type and quantity).
- Optional: new blend door actuator if old one is failing or was damaged.

Final notes
- This is a moderate‑to‑major interior repair: expect several hours to a full day depending on model and experience.
- Follow vehicle‑specific shop manual for exact fastener locations, torque specs, and any model‑specific steps (some Toyotas require dash removal or steering wheel removal).
- Test thoroughly for leaks and heater operation before finishing.

- Why: If the MAF sensor is damaged or contaminated beyond cleaning, it can give bad readings that trigger check-engine lights and poor running.
- What to buy: OEM MAF sensor or quality aftermarket unit matched to your vehicle.
- Hoses and clamps
- Why: Cracked vacuum or intake hoses allow leaks.
- What to buy: Rubber vacuum hoses and correct-size clamps or Oetiker clamps if used on your model.

- Step-by-step procedure (follow order; read all before starting)
- Prepare workspace, gather tools and new filter, park cool engine, open hood.
- Visual inspection first: trace the airbox, note clamps, screws, MAF sensor, intake duct and vacuum lines connected.
- Disconnect battery negative terminal if you will unplug the MAF sensor.
- Remove intake duct/snorkel:
- Use screwdriver or socket to loosen the worm-drive clamp at the throttle body or duct.
- Use plastic pry tool to release plastic clips where the duct meets the grille or fender.
- Pull the duct off gently; use pliers for spring clamps if present.
- Unclip or unscrew the airbox top:
- Remove screws or unclip retaining fasteners around the airbox lid using screwdriver/ratchet.
- If clips are plastic, pry gently to avoid breaking; replace if they break.
- Lift the airbox top straight up; some models will have the MAF sensor attached—do not yank.
- Remove the air filter element:
- Lift filter out and inspect: oil, heavy dirt, holes, crushed pleats require replacement.
- Clean the lower box with a vacuum or wipe with a dry lint-free cloth.
- Inspect airbox sealing surfaces and rubber gaskets:
- Look for cracks, warped mating surfaces, torn gaskets, or broken tabs.
- If gaskets are perished replace them; a poor seal causes unmetered air.
- If the MAF sensor is attached to the airbox and you need to remove it:
- Unplug the electrical connector by pressing the tab and pulling gently.
- Remove screws (Torx or Phillips) and lift sensor straight out.
- Use MAF cleaner spray to clean the element if lightly dirty—spray per product instructions and let dry fully before reinstalling. Do not touch the element.

- Pull off gently with pliers or by hand; inspect for cracks and replace if hardened/cracked.
- Inspect housing for damage:
- If minor crack: temporary epoxy/silicone can seal, but replace the housing for reliability.
- If broken mounting tabs or large cracks: order replacement housing.
- Reinstall filter and reassemble:
- Seat the new or cleaned filter correctly into the lower box with pleats oriented as originally installed.
- Fit lid down squarely, reattach clips/screws and tighten clamps snugly — do not overtighten plastic screws.
- Reconnect ducting and tighten clamps, reconnect any vacuum lines or sensors.
- Reconnect MAF and battery if disconnected:
- Plug MAF connector fully until it clicks.
- Reconnect negative battery terminal and tighten the nut securely with a wrench.
- Start engine and check:
- Look for intake air leaks (hissing sound, rough idle).
- Watch for check-engine light; if present, it may clear after a few drive cycles or require code read/clearing if MAF was disturbed.
- Test drive to confirm normal performance and no whistling or sucking noises around airbox.

- Common beginner mistakes to avoid
- Forcing plastic clips until they break — use trim tool and slow pressure.
- Touching or scraping the MAF element — it’s delicate and easy to damage.
- Reusing degraded clamps or hoses that won’t seal — replace them.
- Not seating the filter or lid squarely, causing vacuum leaks.

- How to tell if a part needs replacing (quick checks)
- Air filter: black, oily, torn, or packed with debris — replace.
- Airbox: visible cracks, broken tabs, or large deformations — replace.
- Hoses: soft/pliable is OK, but if brittle, cracked, or sticky, replace.
- MAF: persistent check-engine codes related to mass air flow or poor cleaning results — replace.

- Final tips
- Keep fasteners and small parts in a tray so you don’t lose them.
- Buy OEM part numbers where possible for guaranteed fit; bring the old filter/housing to parts counter if unsure.
- Regular maintenance: replace air filter per scheduled maintenance (typically every 12,000–30,000 miles depending on conditions).

### Overview of Shock Mount Replacement on a Toyota Chassis Body

**Theory Behind the Repair:**

Shock mounts connect the shock absorbers to the vehicle's chassis. They serve two primary functions:

1. **Damping**: They allow shocks to absorb bumps and irregularities in the road, providing a smooth ride.
2. **Stability**: They help maintain the vehicle's alignment and handling characteristics.

Over time, shock mounts can wear out due to exposure to road conditions, vibrations, and stress. A worn shock mount can lead to noise, decreased ride quality, and poor handling—similar to trying to balance on a wobbly stool.

### Components Involved:

1. **Shock Absorber**: A hydraulic device that dampens the impact of bumps.
2. **Shock Mount**: The rubber or polyurethane component that connects the shock to the chassis.
3. **Mounting Bolts**: Fasteners that secure the shock mount to the chassis and shock absorber.
4. **Washer**: Distributes the load from the bolt head over a larger area.
5. **Nut**: Secures the mounting bolt in place.

### Tools Required:

- Socket wrench set
- Torque wrench
- Ratchet and extension
- Pry bar
- Jack and jack stands or a lift
- Safety glasses
- Gloves

### Steps for Shock Mount Replacement:

1. **Safety First**:
- Park the vehicle on a flat surface and engage the parking brake.
- Wear safety glasses and gloves.

2. **Lift the Vehicle**:
- Using a jack, lift the rear or front of the vehicle depending on which shock mount you are replacing.
- Secure the vehicle with jack stands.

3. **Remove the Wheel (if applicable)**:
- If you're replacing a rear shock mount, you may need to remove the wheel for better access. Use the socket wrench to remove the lug nuts and take off the wheel.

4. **Locate the Shock Absorber**:
- Identify the shock absorber and the shock mount at the top and bottom of the shock.

5. **Remove the Shock Absorber**:
- Use a socket wrench to remove the bolts securing the shock absorber at both ends (top and bottom).
- If the bolts are rusted or stiff, a penetrating oil may help loosen them.
- Once removed, gently pull the shock out of its mount.

6. **Remove the Old Shock Mount**:
- The shock mount is typically held in place with bolts. Use the socket wrench to remove these bolts.
- Carefully pry the old shock mount off if it’s stuck, taking care not to damage surrounding components.

7. **Inspect the Area**:
- Before installing the new mount, inspect the shock absorber for any signs of damage or leakage. If the shock is damaged, replace it as well.

8. **Install the New Shock Mount**:
- Position the new shock mount onto the chassis. Align it with the holes for the mounting bolts.
- Insert the bolts through the shock mount and tighten them by hand first, then use the socket wrench for a snug fit.

9. **Reinstall the Shock Absorber**:
- Position the shock absorber back into its mounting points.
- Secure it with the bolts you previously removed, ensuring they are tightened properly.

10. **Reattach the Wheel (if applicable)**:
- If you removed the wheel, place it back on and hand-tighten the lug nuts.
- Lower the vehicle slightly to put weight on the wheel, then use the torque wrench to tighten the lug nuts to the manufacturer’s specifications.

11. **Lower the Vehicle**:
- Remove the jack stands and lower the vehicle completely.

12. **Test Drive**:
- Take the vehicle for a test drive to ensure that the ride feels stable and that there are no unusual noises.

### What Can Go Wrong:

- **Improper Installation**: If the shock mount is not securely fastened, it can lead to a loose fit, causing noise and compromised handling.
- **Damaged Shock Absorbers**: If the shock absorbers are not in good condition, replacing mounts alone won’t solve ride quality issues.
- **Corrosion**: Old bolts and mounts can be corroded, making removal difficult. Always inspect and replace as necessary.

### Conclusion:

Replacing shock mounts is crucial for maintaining ride quality and vehicle handling. By carefully following the steps and understanding the components and their functions, you can successfully perform this repair, ensuring a smoother and safer driving experience.
