Cracked Radiator, what other ar radiator can fit?

God another problem, let's start from the beginning last week I resolved the overheating Problem by purging the coolant and adding head gasket, radiator and block seal and after cleaning put new coolant, so yesterday I noticed coolant under my car like a couple of teaspoons I checked it and the radiator it's cracked from the top going down on driver side near the battery like 2" and I tried to fix it with crazy glue and a high temp glue ( it's crazy I know) :screwy: but today it leaked like 1/2 cup I went to pep boys and it cost $200 to replace it went radiator.com $140 and $160 but they said that my car radiator it's tricky that's why that price and no returns so my ???? are.

1: Why did it cracked in the first place ? could it be because I replace the cap with one of 16LB (The other read 15LB, but I replaced it like a month ago).

2: I'm going to the "pick your part place or ebay" but i need to know what other radiator can fit like grand am or any other, don't want to waste my time and monney ( not now).

forgot 89 2.8 FI

Radiators do fail from time to time and with the plastic radiators they can fail for any reason at any time. Try car-part.com and you should be able to locate a radiator and it will give you a host of cars that have the same radiator as your car. I believe one from a Regal, Lumina or another Grand Prix and a few others will work. Good Luck!

I bought a new radiator for $100 with 1 year warranty I think it'll be better in the long run. Thanks Anyways GTP_Dad
