Toyota Yaris: Owner Maintenance / Engine Coolant

Toyota Yaris XP210 (2020-2025) Owner's Manual / Maintenance and Care / Owner Maintenance / Engine Coolant

Inspecting Coolant Level

Inspect the antifreeze protection and coolant level in the coolant reservoir at least once a year—at the beginning of the winter season—and before traveling where temperatures may drop below freezing.

Inspect the condition and connections of all cooling system and heater hoses.

Replace any that are swollen or deteriorated.

The coolant should be at full in the radiator and between the F and L marks on the coolant reservoir when the engine is cool.

If it is at or near L, add enough coolant to the coolant reservoir to pro- vide freezing and corrosion protection and to bring the level to F.

Securely tighten the coolant reservoir tank cap after adding coolant.

If the coolant reservoir is empty or new coolant is required frequently, consult your Toyota dealer.

Changing the coolant should be done by your Toyota dealer.

WARNING

Do not use a match or live flame in the engine compartment. DO NOT ADD COOLANT WHEN THE ENGINE IS HOT

A hot engine is dangerous. If the engine has been running, parts of the engine compartment can become very hot. You could be burned. Carefully inspect the engine coolant in the coolant reservoir, but do not open it.

Pull over to a safe location, then switch the ignition to off and make sure the fan is not running before attempting to work near the cooling fan

Working near the cooling fan when it is running is dangerous. The fan could continue running indefinitely even if the engine has stopped and the engine compartment temperature is high. You could be hit by the fan and seriously injured.

Do not remove either cooling system cap when the engine and radiator are hot

When the engine and radiator are hot, scalding coolant and steam may shoot out under pressure and cause serious injury.

NOTICE

Radiator coolant will damage paint. Rinse it off quickly if spilled.

Use only soft (deionized) water in the coolant mixture. Water that contains minerals will cut down on the coolant’s effectiveness.

Do not add only water. Always add a proper coolant mixture.

The engine has aluminum parts and must be protected by an ethylene-glycol-based coolant to prevent corrosion and freezing.

DO NOT USE coolants Containing Alcohol, methanol, Borate or Silicate. These coolants could damage the cooling system.

DO NOT MIX alcohol or methanol with the coolant. This could damage the cooling system.

Do not use a solution that contains more than 60% antifreeze. This would reduce effectiveness.

Use of engine coolant specifically designed for the YARIS/YARIS HATCHBACK is required when replacing engine coolant. Using engine coolant that is not specifically designed for this vehicle may cause serious damage to the engine and cooling system. For questions on how to obtain this specially designed coolant, contact your Toyota dealer.
