New thermostat, wont open ?

[corey240]

I installed the new thermo, I picked up the more expensive one from advanced, it works fine in my friends ser. So it will work fine in my det until I get my nismo. I installed up, hole up. Put the fluid in. It got warm, up to temp. I was waiting for the radiator fluid to get lower like it shold, but it never did. So i drove it up the street, I got on it once and it got hot as shit.

So I went home, no pressur ein the lines, so I opened the cap. Its like the thermo isnt opening? Im not shore. I dontknow trhermos, and I know how to bleed a system. So would my thermo be stuck closed?

try another one.

maybe its just bad luck that you got a shitty one. Thermo's tend to do that.

or

did you have any overheating problems prior to this? if so that's a different story.

No problems befor, its just cold and I need heat in my car. Im gona try it againa nd see if its not gona work. Theres no reason it shouldnt work.

make sure you have all the air out of your cooling system. its sounds like you might be air locked. run it on a driveway with the cap off and add as needed.

this should do the trick. otherwise you have a faulty thermostat

I drove it again, now the temp nedle sitsw slightly below the high line. When I drive it, it gets hotter. It wont hold a low temp. The fluid isnt moving inside the radiator. Should it be safe to say its a bad thermo?

I went to advanced, they were closed. So I tested it per fsm. Now, my thermometter wouldnt read the temp right, but the thermostat did open. Not too long after the water formed bubbles on the bottom of the pan. So, if the thermo opens, then what could be the problem? Im gona reistall it soon, in the 13 degree werather.

ive beend riving it for a couple days now. After a couple minutes it starts to read really hot. I turn the heat on, doesnt make a difference. I am taking the thermo off now, butm when I opened the drain plug on the radiator, directly after driving, the fluid was pretty cold. Im gona drill 2 more holes in the thermo and make the one bigger. If it doesnt work. Im taking it back. I tested it, and it opens, it seems to open and work on my car. It warms up and holds proper termperature until I drive it a few miles, then it creeps on me.

It's really starting to sound like the problem isn't your thermo :/

take your thermostat out and put it in a pot of boilin water. see if it opens if it doesnt it defected.

my friend got a nismo one and it worked fine for a couple of months but then his car started overheating and the thermostat wasnt opening up all the way so we ended up taking it out and puttin one in from autozone

I thought the same for a minute, and then wondered. Why is this problem happening now? Only after I put on a thermo? It was fine without it. I have dual flexalites, and was only running one, but plugged the other in. Needless to say ti didnt help. What els could my problem be, if this isnt it? I moreso believe theres a serious air pocket hiding somwhere. The motor and stuff isnt even really hot when It says it is. Which leads me to believe there is a pocket of air throwing an error reading on the sensor, which I recently replaced.

bleed that ho, and see what you come up with.

look in FSM for proper bleeding procedure, I already posted it up in another thread in the tech section, but somehow the other picture of the next page is missing...

I drilled 2 more holes at the top near the weap hole, made the weep hole bigger, and installed it. Its beter, I think there is a little air in there but it didnt creep up, I just couldnt tell if the needle moved or not. Since I expect it to go up I tihnk it is. So far, problem solved. Cut the weep valve, drill the hole out bigger, add 2 more holes beside it. Fixed.
