my 1998 dodge grand caravan overheats when it is idling but is fine when i drive. what could cause this? i have driven four hours straight and temperature does not go above normal but after idling for twenty minutes it overheats
Do the cooling fans turn on when the temperature reached about 220 degrees?
The electric cooling fans cool the engine when the vehicle is not going fast enough for the air to go through the radiator. When the engine reaches the preset temperature the fans will engage.
The fans will also engage when the A/C is turned on. Does this happen?
Check the fuses and relays related to the cooling fan circuit. If current is going to the fan then the fan may be at fault.
Let us know how you make out.
