Re: 99 tahoe Cant figure out the problem
Well could be acouple of things right off top off the coolant and see if it over heats again
at idle if it over heats at idle and goes away while driving and radiator is full then you have a fan/ air flow issuse at idle, second thing is if you are low on coolant it will over heat at idle and cool down when the water pump start moving more water, sound like you need to have the system pressure tested to check for leaks and go from there
