Engine will warm up to normal operating temperature of 165°F (74°C) more quickly if engine is under a load condition such as driving. • Vehicle performance, including heater/defroster, will be reduced when engine operating temperature is between 100°F to 165°F (38°C to 74°C). Avoid conditions requiring maximum performance until engine reaches 165°F (74°C). (11) Operate engine at idle (750 rpm) to warm-up engine until WATER TEMP gage (11) reaches a minimum of 100°F (38°C) to begin driving or normal operating temperature of 165°F (74°C). NOTE Perform step (12) in outside temperatures of 32°F to -25°F (0°C to -32°C), if extreme or unusual conditions exist such as heavy windshield frost or when it is difficult to achieve normal operating temperature of 165°F (74°C). (12) Perform Rapid Engine Warm-Up (para 2-70). (13) Check that WATER TEMP gage (11) reads between 100°F to 230°F (38°C to 110°C).
