Was overheating replaced t-stat now wont put out heat

Usually means the head gasket is leaking pressure into the cooling system, or the radiator cap is faulty.

You need to get a hotter stat for winter....plus you need to reduce air flow into radiator. You can reduce flow by installing a piece of cardboard in front of radiator. Please only cover partially as complete coverage coyld cause overheating. You are only teying to reduce not elim
A thumbs up would be greatly appreciated if this answer is helpful to you.

Two different issues. The vents and hot air is caused my a cold air mixture door motor gone bad, it's very common. Replace the blend door motor to fix that issue. Overheating could be caused by many things including non working coolant fan, bad t-stat, bad water pump, low or leaking coolant or excessive buildup in coolant system.

If it overheated i would replace the thermostant and gasket, also make sure its full of coolant, after replacing the thermostat you may have air in system so let it run until stat opens it may boil over a little until stat opens then it will **** coolant into block when that happens fill with coolant, you will need to let it idle for a while before new stat opens, hope this helps, good luck, i think the stat went bad the first time it overheated.

sounds like air pocket in system. try running it with radiator cap off until it hats up and thermo stat opens . might burp it out. Don't drive it , just let it heat up sitting in driveway.

stuck thermostat, replace stat

Do you have heat while driving? If you do, it sounds like air is in the system. 1st check the coolant level to make sure it's correct, as low level will cause no heat at idle, and eventually no heat at all along w/ engine overheating.

are you sure that you put the t stat in the right way??is there anything blocking the rad mud ect ect???did you put more coolant in it after changeing the t stat?...is the water pump working proper?...the head gasket may be leaking..this should help solve your issues

Put in a t-stat. No thermostat can act like a bad thermostat, causing over heating, i too have a 94, it was clacking eradically, turns out it was the t-stat opening and closing about 60 times a minute, so i took it out, it got hot, put a new one in, and no more issues.

I took thermal stat off car again,place it in hot water till the stat open(to see if working).Place stat back in and not put the housing back on,disconnect the top hose,pored anti freeze into hose.Anti freeze started to drip out of thermal stat,as I was filling head the air was being pushed out.I could hear like a whistle,when whistle sound stopped put thermal stat housing on,hooked hoses up.did not over heat and have heat in my car now
