Theres a big rack of them at pepboys with different temperatures written on them(200, 195, 180, etc). Just get one thats the same diameter and the lowest temperature. I Didnt even match them up, i just did it by eye, And it works fine. You just have to make sure that rubber gasket can go around it.

update
 

no bhg (yet haha), just a water pump starting to go bad (and i could see it get worst everyday). funny thing, when i removed it it still seemed to spin alright like the new one. but, no overheating problems anymore! and my car is even a little quieter now. thanks for all your help guys.

See! lol. glad ya fixed it. Overheating problems are always a PITA

[QUOTE=Burn N' Up]Other wise im gonna try cutting a few fan blades out of the flexalite and promote more movement there. I guess i'll find out soon enough. QUOTE]

Do that and sure enough the fans will be in an unbalanced condition and they will crap out shortly when the bearings go. Take a home desktop fan, break off a blade, turn the switch on and watch what happens. It almost sounds like the fans are running all the time which will impede airflow at highway speeds, maybe you should adjust the fan thermostat up a little.

Im here in kuwait and in the summer its usually over 120 degrees, heavy traffic conditions etc.
The way I got mine to run cool was to have a custom radiator made for my car with one more row in it. Ive had it like this for about a year and a half and its never gone over 1/3 temp no matter what conditions here and Im still using the stock fan. I was thinking of getting a perma cool to get some extra horses for the engine though but havn't done it yet.

There isnt a big difference without the fan. I drove my car from my house to my friends with no fan on it and it still felt pretty much the same. Didnt overheat either, But it was a short drive. Ive actually had every belt off my motor except the alternator/water pump, and it still didnt feel much different. Id have to get it checked out on a dyno or something tho lol.
