1991 monteo ,uh oh ! overheats at idle


have a 91 montero,LS,only overheats at idle. what to do.


clutch fan




Well this is a sympton of a failed fan. When the car is in motion the air rushing through the radiator cools the engine, but at a stop with no fan to cool the radiator it will start to overheat. If the fan is working correctly we can look to the next possibility.


thank you ! will check the fan.



It could also be low coolant, bad water pump a clogged coolant hose or even air in the system.
