hey IA, i have noticed that my if i take a short trip my overflow resevior will be full of coolant, and it will be boiling. so i swaped the engine thinking it could be a bad head gasket, and its still doing the same thing!!! the temp gauge seems to be working, and it never goes pass the half way mark. ive noticed that my radiator fans turns on for a short period of time then turns back off. i dont think im loosing any coolant. but one thing to note, is that i have the bypass on the thermostat plugged off because everything else was already connected (b16 head)
what else could it be? do i need a new temp sensor? a new thermostat? a new radiator?a new reservoir? hopefully not a head gasket? thanks for reading and for any help!
