:flame: only from time to time.. i dive all day with ac on and its fine then suddenly starts to warm up... any suggestions i am leaning to the water pump... or radiator.. bc i know the radiators old. 154000+ miles on it. anyone know a ballpark range on a water pump replacement. and installation bc i am pretty sure you have to take off the timing belt cover and possibly the belt... thanks all. going out to take a test drive..
