I have a stock 92 civic ex. The temp gauge keeps going to hot but not over heating. Just replace themostat, didnt fix. I can rev up the engine and the temp gauge goes down. Any help please??

 

you might have a little air in your block, try letting your car warm up with the radiator car off and your heat on high.

 

The heater core is bypassed.

Try draining the coolant, refilling it and bleeding it.

 

does your rad. fan turn on? if not, it could be dued to faulty fan sensor located on thermostat housing..If it is then rebleed your cooling system and make sure you have the right mixture... Also check your fuses...

 

My fan comes on but only for a few seconds. You would think if its that hot it should dtay on for a while..

 

I hot wired the fan to run all the time. But it still wants to over heat. help please. How do i bleed the system of air bubbles?

Worked for my brother's DA.

 

i cant run the heat, the heat core was bypassed.

 

There should be a bleeder screw by the top radiator hose(im not sure on D series). You can fill the radiator to the highest it can go then crack the bleeder screw till you get a constant flow of coolant. That might take all the air out.

 

when i fill the radiator to the top, do I put the cap back on and start the car ?

 

yeah but you dont have too

 

just start it and let it warm up a bit to build pressure( with the cap on) and open and close the bleeder screw
