Unhappy Radiator Replacement


I just replaced the radiator in my girlfriends 94 Corolla. The job (I thought) was fairly simple. Just removed the connected hoses, pulled the old one out, put the new one in and reconnected the hoses. Now....The car runs a little bit hot! Did I miss something? Was there some preliminary check that I should've done prior to changing or after changing? Are there instructions online somewhere that I can read?

Any help would be great!!

Smile engine hot

Try bleeding all the air out of the system. Jack up the car under the frame on the side where the radiator fill cap is and allow the engine to warm up to insure the thermostat is open. Look to see if any air bubbles are coming out filler cap hole in radiator. You could aslo help get air out by squeezing top hose to force out any air.

Why were you replacing the radiator?? Overheating?? Did you replace the thermostat, flush the cooling system, those should have come first???

If the engine overheated, there is a good possibility that the head is now warped and possibly leaking, which will lead to more overheating and eventual engine distruction. Sorry for the bad news.

The car wasn't over heating.

I replaced the Radiator because...it was old I guess. My girlfriend told me that she had to put Anti Freeze in the car just about every day. When I looked at the radiator, I could see where the anti-freeze seemed to be seeping through the top of the radiator. After I pulled it, it looks as though it has never been changed...did I mention the car is 13 years?

I just drove the car a few miles and it didn't over heat. So it looks as though it's going to be ok.
