Fixed it, thanks for everyones help

was bleeding coolant wrong (down hill slope and not jacked up)


reversed parked on a hill and jacked it up and used both coolant bleed valves

 

You should have put in a new thermostat<-----

 

Got your PM. Yeah I would look toward the t-stat. I did the cooling mods when I was in Vegas, including the t-stat, fan switch, rad cap, hondata manifold gasket & water wetter. The t-stat was easy to get to when we did the manifold gasket, but I'm not sure how accessible it'll be with everything in the way - we'll see.

I'll send you a PM if you wanna connect.

^ yeah plz do


but
juss curious why my car ddnt really overheat taht much b4 i changd my radiator but after i change it it overheats a lot easier / faster

 

check your head gasket. Same thing happened to a friend of mine. Replaced radiator, thermostat, waterpump and still overheating and fan not turning on. Then finaly replaced head gasket and everything back to normal operations.

 

crosses fingers and hopes its not my head gasket

 

I would first try giving it a good bleed. This car is harder to bleed than most. I jacked up the front of the car until the radiator was the highest point in the system. Then I ran the car and used the bleeder valve on the firewall to get rid of any excess air until the fans cycled 2 times. With the crack in your radiator it could have sucked in some air and made it so your thermostat would not open. And even now if not properly bled your thermostat won't open. Really couldn't hurt to try bleeding it again seeing as it costs you nothing. Make sure you have your heater on all the way inside the car as well.

 

I had this same problem on my old Z28 and it was the fuse that was linked to the fan.

 

for sure bleed it. what is happening is that you probably have an air bubble in the pump, and its not moving fluid. this would be the equivalent of not having any coolant in it at all.

the fact that you are not getting heat out of your heater, coupled with the superfast overheat, leads me to belive this is your problem.

i had the same problem with my ol' rx7. someb*$#@ was a pain to bleed too. had to do it 3 or 4 times before i got all the air out.


i suggest bleeding it, drive it up and down the street untill it gets to regular temp. park it, let it cool down. bleed it. and repeat untill she dosent overheat anymore.

good luck

 

agree on the head gasket, friend just had this issue on a teg, they have tests you can get at the auto store that test for CO2 in the coolant, a good indicator of a head gasket issue. If this is the case radiator replacement won't fix it and it might crack again.

If this test shows its fine check thermostat.
