Parts for your 2022 Toyota Land cruiser-Radiator hose

2022 Toyota Land Cruiser radiator hose

Based on technical sources, a radiator hose is absolutely used on the 2022 Toyota Land Cruiser (300 Series). The Toyota Land Cruiser 300 Series Repair Manual (Cooling System — V35A-FTS petrol and F33A-FTV diesel) and the Toyota Electronic Parts Catalogue for the 2022 J300 list and illustrate both the upper and lower radiator hoses, confirming they’re standard components on this model.

The radiator hoses on a 2022 Land Cruiser do the simple but vital job of shuttling coolant between the engine and the radiator. The upper hose carries hot coolant out to be cooled, and the lower hose returns it to the water pump. On a big, twin‑turbo V6 or modern V6 diesel that tows and tours across Aussie heat or Kiwi backroads, those hoses help keep temperatures bang on, protecting head gaskets, turbos, and everything under the bonnet. They’re moulded, heat‑resistant EPDM hoses designed to handle pressure, vibration, and plenty of corrugations.

As part of regular servicing, they’re worth a close look every 10,000 km or six months. Under good light, squeeze along the bends for soft spots, check for surface cracking, swelling near the clamps, oil contamination, crusty white or pink residue, or rub marks from accessories. Spring clamps should hold firm, if there are “worm-drive” clamps, ensure they’re not biting into the rubber. After water crossings or dusty trips, re-check for grit under clamps and any nicks from stones.

Replacement isn’t strictly mileage‑based, but many workshops treat hoses as consumables around 6–10 years or 150,000–200,000 km, sooner if there are any signs of ageing or heat stress. On the J300, it’s smart to refresh both upper and lower hoses together and fit new quality clamps. Stick with Toyota Super Long Life Coolant (pink), and don’t mix types. A proper bleed is crucial: fill slowly, run the heater, burp out air, top up the expansion tank, then recheck once it’s cooled.

• Let the engine cool fully and safely relieve pressure.
• Drain coolant into a clean container for correct disposal.
• Release clamps, twist the hose to break the seal, then remove.
• Clean mating necks, lightly lube with fresh coolant.
• Install the new hose in the same orientation, fit new clamps.
• Refill with the specified coolant, bleed air, and leak‑check at operating temp.

Post‑service, keep an eye on the level for a few days and scan for any weeping at the necks. A tidy cooling system means stress‑free towing and touring.

How often should the radiator hoses be replaced on a 2022 Land Cruiser?

They should be inspected every service and typically replaced around 6–10 years or 150,000–200,000 km, or earlier if any wear is spotted. Vehicles that tow heavy, run in high heat, or see rough tracks may need new hoses sooner.

What coolant should be used after a hose replacement?

Use Toyota Super Long Life Coolant (pink), premixed to the correct ratio. Don’t mix coolant types. Fill and bleed the system properly, run the heater, and recheck levels once cool. For exact capacity, refer to the owner’s manual or workshop data.

Is it safe to drive with a small radiator hose leak?

It’s risky. Even a small leak can quickly lead to overheating and expensive engine damage. Stop, let it cool, top up if necessary only to move the vehicle safely, and arrange a repair or tow rather than pressing on.
