Coolant shooting out of overflow reservoir.

thanks for all the input guys. so here's what the problem was. a combination of things (of course) seems to have been the problem. partially blocked radiator (from stop leak), a leaking thermostat housing gasket (standard gasket not working properly due to a worn out housing), and apparently a possessed thermostat (very aggravating since i have owned the car for a little over 2 years and have gone through 3 or 4 thermostats and not a one was worth a darned! so i have removed the thermostat out completely. sandwiched 2 gaskets for thermostat housing and used a little grey rtv. also had to tap the housing back into shape. no whacky heating issues and no coolant shooting out as far as i can tell.

I could have sworn you said you changed the thermostat already.

 

[Boost231]

he said he did 3 or 4 times.

I think he's wearing rose colored glasses but maybe not. Good luck, dude.

lol! the most recent thermostat i put in was about 6 months ago..... i will worry about another one come oct/nov. until then, hopefully i can actually enjoy this car....

Thermostats just dont go bad at the rate youre talking about but like I said, I hope it works out for you. Id be pulling the engine personally.

 

[84sithlord]

do you think stop leak will gum up a thermostat?

Anything is possible but given the symptoms, I still think its a HG.

I've seen 1 or 2 thermostat failures in my life on all cars I've worked on. They don't go bad too often. If you had 4 thermostats in there and the symptoms are repeatable it's time to pull it out as jay suggested.

 

[84sithlord]

roger that. thanks guys!

 

[Boost231]

you would think now that the t-stat is out it would show bubbles more and sooner? does it still bubble with the cap off?

 

[84sithlord]

no bubbling. everything seems to be flowing as it should. no coolant smell from exhaust. no exhaust smell in coolant.....no bouncing temps....im still a bit on edge though. lol!

I say run it till you see stuff coming out the overflow and keep a close eye on your dipstick to ensure you don't get any milkshake

 

[84sithlord]

will do! thank you!

 

[Boost231]

how about a cheap leakdown tester?

 

[84sithlord]

sure. can i get them at advance auto?

 

[Boost231]

harbor freight maybe.

 

[84sithlord]

cool. i will look into it. i know a couple of tool trucks come by my work twice a week. i will see what they have. i doubt it will be cheap though! lol

 

[84sithlord]

screw it! i'm gonna change the head gaskets...stupid car ran cool as a cucumber for 45 min while on the highway. as soon as i pull of the highway, within a half mile, i went from 160-235ish. i turned car off. notice fracking coolant has been overflowing. i opened up reservoir and see nice sized air bubbles coming up out of it.
