Vehicle Service and Care 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 COLD 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 Coolant Engine Coolant for more information. The coolant reservoir is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 9-6 for more information on location. The coolant level should be at or above the top mark on the coolant reservoir dipstick. If it is not, you may have a leak in the cooling system. 9-17 How to Add Coolant to the Recovery Tank { CAUTION 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.
