Parts for your 2022 Toyota Land cruiser-Radiator

2022 Toyota Land Cruiser Radiator

The 2022 Toyota Land Cruiser (J300 series) absolutely uses a radiator. Toyota’s technical literature for the LC300—namely the Land Cruiser 300 Series Repair Manual (Cooling System – Radiator) and the Toyota Electronic Parts Catalogue for J300—details a front‑mounted aluminium radiator as part of the liquid engine‑cooling system on both the V6 twin‑turbo petrol (V35A‑FTS) and V6 twin‑turbo diesel (F33A‑FTV) variants. That makes the radiator directly relevant to this model.

On this Land Cruiser, the radiator’s job is to keep engine temperatures in the sweet spot, even when towing, climbing dunes, or crawling over rocks. Coolant flows through the engine to pick up heat, then passes through the radiator where air flow—helped by the cooling fans and vehicle speed—dissipates that heat. This protects head gaskets, turbos, hoses, and sensors, and helps the engine deliver consistent power and economy. Many LC300s also feature additional coolers (for the transmission or charge‑air circuit), but the main engine radiator remains the core of the system.

As part of regular servicing, it pays to keep the radiator and coolant in top nick. Toyota specifies long‑life pink coolant, the typical factory schedule is up to 160,000 km or 10 years for the first coolant change and then every 80,000 km or 5 years thereafter—owners should confirm the exact interval in the service book for Australia or New Zealand. Using genuine or equivalent OAT long‑life coolant is key, don’t mix colours or chemistries.

• Check coolant level under the bonnet when the engine is cold and top up only with the correct premix.
• Inspect hoses, clamps, and the radiator cap for stains, cracks, or a sweet coolant smell—early signs of leaks.
• Keep the fins clean. After mud, bugs, or seed grass, rinse gently from back to front with low‑pressure water to avoid bending fins.
• If the temp gauge climbs while towing or off‑roading, ease off and have the cooling system pressure‑tested.

When replacement is due (impact damage, internal blockage, or persistent overheating), go with a quality OEM‑spec radiator. It’s smart to renew the cap, thermostat, and any tired hoses at the same time. A proper refill/bleed—ideally vacuum‑filled—prevents air pockets. After refitting, verify fan operation and take a steady test drive, watching temperature and heater performance. With the right care, the LC300’s radiator will handle Aussie heat and Kiwi hills without breaking a sweat.

FAQs

How often should the coolant be changed on a 2022 Land Cruiser?
For most LC300s using Toyota Super Long Life Coolant (pink), the first change is typically at up to 160,000 km or 10 years, then every 80,000 km or 5 years. Always confirm the interval in the owner’s manual or service log for local conditions in Australia or New Zealand.

What are signs the radiator needs attention or replacement?
Watch for rising engine temps, low coolant with no obvious leaks, discoloured or sludgy coolant, crusty deposits around the cap or tanks, swollen hoses, or damp spots on the radiator core. After heavy towing or off‑road use, a persistent hot‑running engine can also point to a partially blocked core.

Can they keep driving with a small radiator leak?
It’s risky. Even a slow leak can turn into rapid overheating, which may warp cylinder heads or damage turbos. If a leak is suspected, top up with the correct coolant if safe to do so and arrange inspection promptly rather than pushing on.
