WTF thermostat! I did an emissions removal a little bit ago and while i was taking off the manifold I just thought I'd replace the thermo too. Well it started overheating QUICK once i threw everything back together. I took out the thermo and ran it, Temps were fine system bleed out nicely. So I got a thermo from Nissan Installed it and BAM! overheating, the thermo refuses to open, nothing coming out of the blurp hole, hot air, bleeding the system correctly, losened the upper heater core hose. NOTHING the damn coolant WONT FLOW. This is really starting to piss me off. I did this a little bit ago with no air problems. Im thinking there is only air hitting the thermo and not coolant?! HOw do i get the damn coolant to flow to the thermo?! Any help would be appreciated, tips & tricks??

Where you running a thermostat before you changed it?

Maybe you got a bad thermostat, get another one.

Did you put the juggle valve on top when you installed the thermo(s)?

i would use a radiator testor thing.just replaces where your rad cap goes, then while the fluid is in start to pump the radiator with pressure and see how high it gets.

a way u can test thermo is to boil some water on the stove and throw in the thermo and see if it opens, if not then theres ur problem. if it does open, then ur SOL lol
