What could cause 99 subaru impreza to overheat the radiator is fine?
water pump might have broken.
i have this problem now, the radiator is full of antifreeze, but since water pump is not circling it around, the engine keeps overheating.
dont wait till your engine stucks, fix the problem as soon, as possible.
its cheaper than buying a new engine/car.
The Mercury Villager and Nissan Quest are basically the same vehicle. The radiator is cooled by an electric fan and thermostat. If either of these are malfuntioning, that could be the cause. Otherwise, all of the normal things such as low coolant, bad water pump, clogged radiator, bad radiator hoses, bad thermostat,and incorrect timing could all cause the engine to overheat.
to add to this, a big YES,on the radiator cap .the radiator cap needs to be specific pressure rating. radiator caps do wear out. also the cheapest fix to start It is doubtful a radiator cap would cause a car to overheat. Common overheating causes are insufficient coolant, leaking coolant (into or out of your engine), faulty thermostat, blown cooling fan fuse, faulty fan temperature switch ( sender ), faulty fan, or a faulty fan…
