Problem 2 : Overheating
(1) Items to be checked for ahead
Overheating might also be caused by abnormal operating conditions. If the engine is over-
heating but its cooling system is not cont-
ributing to this trouble, it is necessary to check the difference between the ambient temper-
ature when the engine is in normal operation
(with the thermostat fully open). If the ambient temperature is higher than the normal
coolant temperature by more than 140 F(108 C), investigate other items than those related to the
engine cooling system.
• Insufficient coolant and exterior coolant leaks
• Loose fan belt
• Radiator core openings plugged with dirt
