New thermostat overheating!!

[B-Boy DuB-L]

So i replaced my thermostat. it is sealed good and everything. when i go to open the air relief valve the head of the bolt breaks off. So im like ok, ill just have to shake the car and wait it out for the air bubbles to escape. Idling the car will not overheat but when im driving after alil less then 5 minutes it will. So i leave the radiator cap off and start the car. I see bubbles coming out and i get excited. But now there is not really any bubbles coming out just the coolant is overflowing massively. It gets so bad that i have to turn my car off because it starts smoking.I need help!!!! fast. I need to go somewhere tomorro and i was working on it from 130pm till 815pm i cant ****ing bleed this ****. i just want to throw my car out

[Gabes13]

did you put it in backwards

[B-Boy DuB-L]

No i made sure the jiggle valve **** was on top and it was facing the right way. I mean i did get it from pepboys, idk if that has anything to do with it?

[B-Boy DuB-L]

And I did all of this in my school parking lot FTL btw

run without a thermostat and see if you still have the problem.

i put a "new" thermostat in my girls coupe and it was bad.

[B-Boy DuB-L]

dam ima need more coolant then

[Flicktitty]

dam ima need more coolant then

try water FOR NOW. no need to waste the money if thats not the fix.

[B-Boy DuB-L]

the thing is i did use water to flush it. i ran it and no signs of overheating so i thought it was good and it was with the new thermostat.

i would take the thermostat back and go to nissan. i have had nothing but problems with aftermarket thermostats. take the ****ing thing out for now and go buy one from nissan.

can i drive my car without a themrostat?

[n240sxfnatic]

can i drive my car without a themrostat?

Yes you can

[B-Boy DuB-L]

then what is the point of the thermostat being in the car for the first place. Is it to control the temperature and therefore control the emissions?

[n240sxfnatic]

google it a lot of ppl dont run thermostats as it can give a lower water temp. If you live in a cold climate you should run one as your car will take forever to warm up if you dont. A thermostat just controls at what temp more coolant is circulated through the engine so without on it would just constantly.

[slyedog240sx]

just cap the thing off and still see if it get's hot. If it gets hot then shut it back down. If you broke the bleeder screw in the intake off seal it with some expoxy in a tube that you knead to activate.Looks like playdough. You are turning the heater on high before bleeding it i hope.See if both the upper and lower hoses are getting hot.If the lower isn't then the thermostat isn't working.

[B-Boy DuB-L]

Yea i have the heater on high. The top rad hose is getting hot. I didnt check the lower rad hose. I would assume its hot if the top one is. It stays at normal operating temperature while it is at idle. But after i drive for a little bit it starts to go up slowly. so idk what the problem is. I think i'm going to jack the car up at let it run. The only problem i get is that the coolant overflows and starts smoking

[slyedog240sx]

overflows from where? The neck?

[IDRFT95S14]

it starts to smoke? what color smoke?

[B-Boy DuB-L]

Yea from where the cap goes. And sometimes it like squirts out, kinda like a waterfall. I was thinking that something was blocking it and thats what is causing the overflow, that would be from the thermostat.

[B-Boy DuB-L]

its just white smoke from the engine bay where the coolant spilled out of

[jismo]

i have a spill saver coolant funnel that i got off that MAC tool truck that i use to burp the system when i think theres air present. it mounts to the rad, and i pour a little coolant in and squeeze the upper rad hose to push the air out and watch for bubbles in the funnel.the only time my car has overheated is when i didnt add enough coolant in the rad.

[IDRFT95S14]

this overheating issues are hard dude it could be any damn thing thermostat, water pump, any rad leaks or on hoses but im sure you already checked for leaks

[jismo]

or the pellet in the themostat my be bad.aftermarket right. try takeing it out and heating it up to see if it opens up fully.

[B-Boy DuB-L]

yea i already checked for leaks. Of course thats like the first thing you check wen u are done with everything during the bleeding process. this really pisses me off though. I just did everything and now i have to redo it cuz of a faulty thermo and have to buy more coolant.

[jismo]

how old is your rad cap?

[B-Boy DuB-L]

i have no clue ima say 2 years-ish but even with the rad cap off the coolant like jumped out

[slyedog240sx]

just check the lower hose like i said.

[B-Boy DuB-L]

and if is not hot then the thermostat sucks right?

[slyedog240sx]

it means no circulation as in therm ,or wp, or blockage
