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 surge tank. If the coolant inside the coolant surge 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, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant surge tank, but be sure the cooling system is cool before this is done.

The coolant surge tank is located in the engine compartment on the passenger

The coolant surge tank is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview   for more information on location.

The coolant level should be at or above the FULL COLD mark. If it is not, the vehicle may have a leak in the cooling system.
