This gets my vote for a sticky.

Nice work Shawn.

Thanks. Figured i'd hear more feedback. Oh well, surely this will help someone out there either being ready to do the job or know what there getting themselves into.

BTW, anyone interested in doing this upgrade, read this thread too... http://www.grandprixforums.net/f79/u...ally-3698.html

How much deeper into the engine bay does the radiator go? Will it push the fans too close to a set of headers?

[Iron Indian]

It'll push the fans a little bit more into the engine bay... approx 3/8" i'd guys. I have TOGs and there are no major clearance issues for me. The radiator didn't move the fans that much closer, but it is closer. I doubt you should have a problem with any headers I would think. Do some measuring, surely you have over a 1/2" space as is...

Have you had any issues since you posted this? I would imagine the coolant gauge hardly moves. I'm looking for that kind of dependability without a trans cooler. Thank you very much for the write up.
