Ok i a while back my car ( 92 dodge stealth es ) was over heating and i brought it to a mechanic and they told me it needed a new radiator so me and my dad put a replacment one in, and everything is hooked up normal and right! .... but for some reason my car is still over heating and i have no idea why? it seems like no coolent is circling through the engine! and a lot of air pressure is coming out when i release the air pressure ...... why is my car STILL over heating??

 

it is possible that the water pump is going out or bad thermostat. Also check if your fans turn on when the motor is starting to get hot.

 

it could be the temp sensor located at the bottom of the radiator. it controls the cooling fans, my sons failed, the car overheated

PSSSSSt ,, if u havent replaced the waterpump yet, do it!

 

1) See if the big fan runs when it start to go hot. Make sure its not intermittent. That means a bad connection by the 4 pin connector from the Fan and to the Fuse box. Also check the fuse.
2) Check the relays. Plug and unplug, make sure you don't brake them.
3) Touch the top radiator hose, if its cool the thermostat is stuck in close position. The bottom hose will be very very hot.
4) If your temperature gage works then your sensor is fine.

I had all these problems. Never had the water pump problem.
