10-14 Vehicle Care How to Add Coolant to the Recovery Tank How to Add Coolant to the Radiator { WARNING 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 line marked on the recovery tank. When the engine is hot, the level could be higher than the FULL COLD line. If the coolant is below the FULL COLD line 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. 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. Notice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause the engine to overheat and be severely damaged. If coolant is needed, add the proper DEX-COOL coolant mixture at the coolant recovery tank. { WARNING Steam and scalding liquids from a hot cooling system can blow out and burn you badly. Never turn the cap when the cooling system, including the surge tank pressure cap, is hot. Wait for the cooling system and surge tank pressure cap to cool. If coolant is needed, add the proper mixture directly to the radiator, but be sure the cooling system is cool before this is done.
