I have a 95 z28 that keeps overheating. I've already taken the thermostat out,got the fan running direct from the battery, and it still keeps on overheating need help, anyone got any advice it's my first camaro. What should i check or do next?

 

have u blead the air out?

 

does it overheat in the city or highway? open the rad cap and turn on the car. look if water flows good threw the fins. it might be blocked up wit junk. had the same prob.

 

yeah I already bled the air. Are you suppose to have the car running or off when bleeding the air? Don't know if i did it the right way.

 

When I run it,it shows that it's fine but once i stop the needle goes up and i run it mainly in the city. Know when you see the radiator the water is circulating but does the lbs. on the radiator cap make a difference? It has a 18lbs. cap on it . Is it the right cap? Do you know how many lbs. radiator cap suppose to be? Also, how can u tell when the water pump goes out?

 

ok the car needs to be on to bleed it. leave the cap off and the car running and just kepp filling it up as it goes down. it works alot better if u park on a hill or a inclined drive pointing the nose up. the water should always be circulating no matter wut unless u have a thermo in it, since u dont u should see it moving all the time. the cap psi is like 15 or soewhere close to that from factory. the psi means for every 1psi it reduces the temp by 2 degrees. when the water pump fails the most common way to know is it will be leaking alot of water from it. but if the water is flowing then ur pump is good. ok now u say u wired the fan to be direct did u hook it up the right way? even if u reverse the wires itl still come but in "pushing mode". meaning the fan is going in the wrong direction. turn it on and stick ur hand behind it. itll either push or suck ur hand. check that and let me know.

 

It is pushing you can feel it pushing towards the motor. Is it on the right way?

 

ya thats the right way. do u still have the little plastic air dam underneath ur car. is ur timing correct? are u running str8 water?

 

^^^^add to that,, what condition is the radiator in. are all the finns between the water pasages still there? have u flushed the radiator? any noticable increase in steam coming from the exhaust? water in the oil? oil in the water?

 

air dam is still on, should i take it off? it's running straight water. how can you tell when the timing is off?
