LOOKINFORSPL? Posted December 27, 2010 Report Share Posted December 27, 2010 (edited) thermostat is probably stuck shut not to mention there might be an air pocket in the system causing it to overheat. This^^ The thermostat is only about 6 bucks with the gasket and is usually the problem, also check to see if the thermostat housing has a bleeder screw to bleed air out of the system. If im not mistaken an airbound water pump will decrease water flow. someone correct me if im wrong. Edited December 27, 2010 by LOOKINFORSPL?

dyeagain15 Posted December 27, 2010 Report Share Posted December 27, 2010 Is called doing a pressure test. theres a special attachment that you put on to screw the cap on to it. You pump it up to the psi it says on the cap, if the needle drops the cap is bad. Then you screw the end on the resevoir. Pump it up to the same psi, and if the needle drops theres a leak in the system. Just look for coolant. Good luck to ya, hope its not the head gasket.

crispy_chick3n Posted December 29, 2010 Report Share Posted December 29, 2010 (edited) ok my question is this, how bad was it overheating? if it was overheating to the point where the temp guage needle was pinned on the hot for a while that could have caused internal damage to the engine, mainly scoring to the piston walls, which can cause a loss of compression, excessive blowby, and the one thing everyone is concerned about, reduced gas mileage. anyway back to the cooling system, one thing to do is when the car is cold take the radiator cap off, start the car and let it warm up to normal operating temp (usualy around 210F) at that point you should be able to shine a light into the radiator and see the coolant flowing. if it isnt flowing at around 210 degrees f your thermostat is stuck shut, that isnt too bad, the thermostat isnt expensive at all. im almost positive that from what you are describing your thermostat is to blame.

Thanks man that is what i am thinking to. As far as getting the radiator cap off that is a challenge in itself. Quote Link to comment Share on other sites More sharing options...
Gotloud555 Posted December 30, 2010 Report Share Posted December 30, 2010 Problem in general. Could be water pump or thermostat not working properly. The Radiator fan must come on to keep the car engine cool. Quote Link to comment Share on other sites More sharing options...
crispy_chick3n Posted December 30, 2010 Report Share Posted December 30, 2010 (edited) The Radiator fan must come on to keep the car engine cool. this is not 100% true, it is but a myth, as long as you are moving forward in direction air is passing through the radiator, cooling the coolant. all the fan does is help pull air through the radiator when you arnt moving, or if the car is realy hot. other than that the fan up front is useless and a waste of valuable power.
