Adding Coolant If more coolant is needed, add the proper DEX-COOL® coolant mixture at the surge tank, but only when the engine is cool. Coolant Surge Tank Pressure Cap Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. The coolant surge tank pressure cap must be fully installed on the coolant surge tank. See Engine Compartment Overview on page 5-12 for more information on location. {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. When replacing the pressure cap, make sure it is hand-tight and fully seated. Engine Overheating There are two engine hot messages that could be displayed in the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-53 for more information. If the engine is overheating, then you will find a coolant temperature gage and a coolant warning light on the instrument panel. See Engine Coolant Temperature Gage on page 3-40 and Engine Coolant Temperature Warning Light on page 3-40 for more information. 5-26
