OK my girlfriend has a grand am that for some reason or another loves to overheat sporadically and i mean SPORADICALLY. This thing will be fine for 2 or 3 weeks and then all of a sudden it will spike to red hot temps, shut the car off and sometimes its fine but other times it isnt. It has been to the mechanics three times now and each time they find something else to replace which is beginning to make me think they are incompetent and/or taking her to the bank. I refuse to let her take it back to them and will prbably have her take it to my mechanic from now on (hers has been a family mechanic and her parents take offense for her switching or it would have been done sooner) anyway it has a new headgasket, new water pump, new seals, the only other thing i can think of is simply a thermostat if they did not do it. I am just wondering if a sensor like the thermo or the something is wrong. Any other ideas would be greatly appreciated however if this is yet another mystery problem she might just buy my Xterra and I will come back to either the Supra/350Z crowd or join possibly the Evo world
either way its win win for me hehe
