I just changed my thermostat gasket for the 4 time now and its still leaking. what could be the ?you may have cracked the housing a little bit on it that will make it leak like that and you wont be able to see the crack it will be so small that the human eye sometimes wont spot it,id check that real close,that car should have a 3.8 in it and they was bad to crack if the thermostat wasn't installed exactly right in it,they crack real easy when they get old,any auto parts store sells new housings so replacing it wont be a problem,good luck and happy new years,I need help. I just changed my thermostat gasket for the 4 time now and its still leaking. what could be the ?you shouldn't have to use a permatex gasket with the thermostat. If the thermostat comes with a gasket than you should be fine. I would check over the housing and look for small cracks in the metal maybe its cracked from age or from over tightening. also make shore that all the mating surfaces are very clean and free from any type of sealant or dirt. The last thing that I can think of is that you have to tighten the bolts down in sequence meaning that they have to be tightened across from one another and also with equal turns because if one bolt is tighter than the other than this will cause the housing to not be able to sit flush against the block.I need help. I just changed my thermostat gasket for the 4 time now and its still leaking. what could be the ?First of all make sure the thermostat is fitted the correct way with the spring end to the engine side and not into the top hose.try using %26quot;instant gasket%26quot; (silicon sealer the type used on fish tanks) apply it to both sides of the gaskets . do not over tighten the thermostat housing bolts. If you torque the bolts to 6 ft/lbs with thread lock applied, this may do the trick. Good luckI need help. I just changed my thermostat gasket for the 4 time now and its still leaking. what could be the ?You have to scrape the old gasket off the block and spout connector for the top rad hose. DON'T use the cheap cardboard gaskets with the sticky backing. Use a rubber gasket and sealant. When tightening the two bolts where the gasket is dont tighten one all the way down try to do them evenly . If u tighten one all the way down u move all the sealant to one side and can make a air bubble.That will cause it to leak.I need help.
