Overheating HELP!!!

[s13drift_89]

i have a problem w my car overheating. it started when i saw some coolant smoke coming out from underneath the hood. i did a visual inspection and saw that the radiator was cracked. i tried to do a quick fix by using some of that radiator patch but that only lasted like3 days so i replaced the radiator. ever since then the cars has been overheating irratically and the heater isnt as hot as before. people had told me to flush the radiator again so i did but it still overheats sometimes. is it possible that while the radiator was cracked lack to the head caused it to warp??I did change the thermostat to. when i drive it for a while the heat works and gauge goes back to the middle/

a little help??

Sounds to me like you still have air in the system somewhere. Sombish's are a pain to get the air out of. There's a pretty good write-up around here on how to get a majority of the air out the first go around.

what radiator patch did you use? If its that liquid one that you pour into your radiator that's supposed to seal up cracks or what not, that may be the problem. If anything, I'm thinking that crap got its way to your water pump.

if it's overheating AND your heater isn't working, i'm voting for air in your system and a bad thermostat.

try replacing your radiator cap!

I changed the thermostat. How do u get air out cause I left my car on for about 30-45 min without the cap and still does it. I was told thats how to do it.

FSM FTW.

there's a bolt on the upper water neck. 10mm. you take it out and fill the radiator until water comes out. then put the bolt back in to stop the water coming out.

then fill the radiator. start the car with the heat turned to the "Hot" position.

let it run to operating temperature. continue to monitor fluid level.

fill coolant overflow. when engine is warm and coolant is flowing (upper and lower hoses warm/hot), top off the radiator and install radiator cap.

let engine cool, if there is any air in the system, the overflow should compensate and "bleed" the system.

but it's all in the FSM. think it says something about racing the motor IIRC.
