either the thermostat or the fan is no good. You would need to locate the thermostat and see if its stuck open or closed!
try checking your cooloing fan. make sure it is running There is no air getting to your radiator as you are not moving! Or there is a problem elsewhere in your cooling system!
Its prob the radiator fan. Or you are out of coolant.
The radiator cooling fan is most likely not working.
You need to check the operation of the radiator fan.
Check coolant level Cooling fan working? Dirt or clogged radiator? Defective radiator cap?
Effectively all the fuel that it burns while idling. You are getting 0 miles per gallon while idling.
If the electric cooling fan(s) are not coming on that may be the problem.
In park or neutral, no.
A bad fan clutch, low on coolant, missing fan shroud, bad thermostat or a plugged up radiator.
A likely cause is an internally restricted radiator.
May have an answer already, but be sure that the radiator is full of coolant.
Check to see if the area between the radiator and the ac condensor is plugged up with whatever. It may be hard to see without taking the radiator out but it could be loaded with leaves or what have you.
