Adding Coolant If you need more coolant, add the proper DEX-COOL@ coolant mixture at the surge tank, but only when the engine is cool. Engine Overheating You will find an engine coolant temperature gage on the instrument panel cluster and a COOLANT OVER TEMP message on the Driver Information Center (DIC). See Engine Coolant Temperature Gage on page 3-38 and DlC Warnings and Messages on page3-53. r 5-26 Youcan bc urnedyou I- I coolantonhot I engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don't spill coolant on a hot engine. Overheated Engine Protection Operating Mode If an overheated engine condition exists and the messages COOLANT OVER TEMP and REDUCED ENGINE POWER are displayed, along with the Check Engine light, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an emergency; you may drive up to 50 miles (80 km). Notice: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life system. See "Engine Oil" in the Index. When replacing the pressure cap, make sure it is hand-tight. Coolant Surge Tank Pressure Cap Notice: Your pressure cap is a pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. See "Capacities and Specifications" for more information. See Engine Compartment Overview on page 5-12 for information on location.
