my 93 mazda rx7 twin turbo has many cooling problems first i had a broken water pump which i replaced myself then i replace the stock pulley on it with a indigo pulley system to bypass my air box however i am have extreme over heating probems by the pressure getting to high i have a 2nd generation conversion overflow in place as well as a pulley system my car runs hot and the cap is holding down alot of pressure but it is getting to hot and not cooling down the overflow popped out of the plastic tank due to the pressure and left steam rising out of the hood as a prelude with a extreme turbo drove by after i pushed the car home i realeazed the pressure in a most delicut manner and filled the radiator up i am running wetter water and tap water how can i get all the air out of the block after filling it up again it just overflowed back into my plastic resivour and back on the street i have put many hours in the car and now do not feel comfturable driveing it more then 10 miles do to the antifreeze bioling out and overheating the block leaveing hot spots which could cuase seriose damage

 

I just realized that there is no periods anywhere, this is one giant sentence bro, breathe!

 

and your spelling sucks...

how do you know its overheating? is the temp guage going past the middle? do you have an aftermarket temp guage? if your coolant seals are bad pressure from the combustion chamber will force coolant to overflow as well...... does the car burn coolant at all?? white smoke?

 

My temps went down by about 20+ degress by turning my fans on high and wiring them where they are always on when the keys are in the ignition.

 

I removed the thermostat and found it wasn't opening very far I removed it from the car. Due to it taking longer to get to running temp my vacume leak has caused for a very rough ride. When the car gets to temp it runs much smother. if you have any suggestions on finding my leak or getting rid of my stutter I would appreciate it. The car stutters around 4000 rpm.
