I have a manual 2000 Honda civic that is acting up. When I drive it after about 15mins it gets really hot. Then right before I pull over it starts to cool off if I have the heat pumping . It also seem to over heat when ever I am sitting idle .
I replaced the radiator and thermostat but I’m still having the problem. Looking for help since I honestly don’t know but my father always told me it was better try and fix something yourself but don’t be afraid to ask for help.
