I have a 98 passport that keeps overheating. I have replaced the thermostat, radiator, and fan clutch. It doesn't run hot when idling but soon as I start driving it starts overheating. I don't have water in my oil and there's no white smoke so I don't think the head gasket is blown.
I have tried everything I can think of. Can the water pump be bad without the bearings being gone or leaking?
