10-14 Vehicle Care How to Add Coolant to the Recovery Tank Checking Coolant The vehicle must be on a level surface when checking the coolant level. Check to see if coolant is visible in the coolant recovery tank. If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. If coolant is visible but the coolant level is not at or above the FULL COLD mark or the FULL COLD ISO symbol mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant recovery tank, but be sure the cooling system is cool before this is done. See Engine Overheating on page 10-16. The coolant recovery tank cap has this symbol on it. When the engine is cold, the coolant level should be at or above the FULL COLD mark or the FULL COLD ISO symbol mark on the recovery tank. When the engine is hot, the level could be higher than the FULL COLD mark or the FULL COLD ISO symbol mark. If the coolant is below the FULL COLD mark or the FULL COLD ISO symbol mark when the engine is hot, there could be a leak in the cooling system. If the coolant is low, add the coolant or take the vehicle to a dealer for service. { Warning You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. { Caution This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause the engine to overheat and be severely damaged. If recovery tank is empty, check the coolant level in the radiator before adding coolant to the recovery tank or take the vehicle to the dealer for service. See "How to Add Coolant to the Radiator" later in this section.
