How to Add Coolant to the Recovery Tank
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.
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.
