I have a 97 passport 4wd that keeps overheating. The radiator was flushed out a week ago then the thermostat replaced, then the fan clutch was replaced. I put a shop rag in front of the radiator and it sucked it in, so that works. The water pump was cycling when we were replacing everything, but it overheated this morning on my way to work (a 10 mile drive--no stop and go traffic). Any solutions to what may be the cause now? What should I look for if it is the water pump, a cracked head, or a bad radiator? Thanks for your help in advance!!
