2022 Toyota Land Cruiser Coolant

Coolant is absolutely relevant to the 2022 Toyota Land Cruiser (300 Series). Toyota’s technical literature—namely the Land Cruiser 300 Series Owner’s Manual (Cooling System section), the Toyota Workshop/Repair Manual (Engine – Cooling), and the Toyota Genuine Super Long Life Coolant (Pink) product data—specifies a liquid-cooled engine and the use of Toyota SLLC. Both the 3.3‑litre twin‑turbo diesel and the 3.5‑litre twin‑turbo petrol engines rely on engine coolant for temperature control and corrosion protection.

In this model, coolant does much more than keep temps in check. It circulates through the block, heads, turbo-related heat exchangers and radiator to carry heat away, helping the Land Cruiser hold steady under towing loads, off‑road climbs and hot Aussie and Kiwi summers. Toyota’s pink Super Long Life Coolant (a pre-mixed P‑OAT formula) also prevents internal corrosion, protects seals and the water pump, and lifts the boil-over margin, so the big wagon doesn’t get cranky when worked hard.

Servicing-wise, Toyota’s schedule for SLLC typically calls for the first replacement at around 160,000 km or 10 years, then every 80,000 km or 5 years thereafter. Sticking with Toyota Genuine SLLC (Pink) matters—mixing colours or generic types can dilute inhibitor chemistry and shorten component life. If a non‑Toyota top‑up happens in an emergency, plan a proper flush and refill with the correct coolant as soon as practicable.

• Check the coolant level only when the engine is cold, the level should sit between the reservoir marks.
• Never open the radiator cap hot—wait until it’s cool to avoid a scalding mess.
• Use only Toyota Genuine SLLC (Pink). It’s pre‑mixed, don’t add plain water unless stranded, and then only demineralised water in a small amount.
• Inspect hoses, clamps, the water pump area and the radiator for leaks, staining or crusty residue.
• After any coolant service, bleed air correctly per the workshop procedure to avoid hot spots and heater issues.
• Dispose of old coolant responsibly—it's toxic to pets and the environment.

Signs it needs attention include rising temps under load, sweet smells, visible leaks, brown/murky coolant or the low‑level warning. A trusted workshop with the correct Toyota spec coolant and bleeding process will keep the LC300’s cooling system rock‑solid for the long haul.

What coolant type does a 2022 Land Cruiser use?

Toyota specifies Toyota Genuine Super Long Life Coolant (Pink), a pre‑mixed P‑OAT formula. It’s silicate, borate and amine‑free, matched to Toyota alloys and sealing materials. Sticking with the genuine pink coolant avoids chemical clashes and protects the water pump, radiator and heater core.

How often should the coolant be changed on an LC300?

Per Toyota’s guidance for SLLC, the first change is typically at around 160,000 km or 10 years, then every 80,000 km or 5 years. Severe duty—towing, heavy sand work or frequent high‑heat use—makes interim inspections smart, even if the interval hasn’t elapsed.

Can different coolant colours be mixed in an emergency?

It’s best not to. If there’s no choice, a small top‑up with demineralised water can get the vehicle home, but plan a full flush and refill with Toyota SLLC (Pink) promptly. Mixing coolant chemistries can reduce corrosion protection and shorten component life.
