2002 GP GT, few mods.

I seem to be having issues keeping my coolant temps down on hot days (90+).

Stock GT rad, 180 thermo, tight fan settings, etc.

I see ZZP's option but i'm not a fan of buying and shipping such a large item.

Other than the GTP rad, there seems to be the 1998 Monte rad as per: http://www.grandprixforums.net/radiator_upgrade.php

Locally all I can find is the 1" rad. (still an upgrade from my 5/8ths core)

Now with the trans cooler fittings my understanding is they'd be different thus requiring new ones.

Since my lines are starting to seep I was tossing around the idea of a standalone fluid cooler with SS lines and AN fittings and skipping the stock cooler.

Another option is to roll down the windows, turn off the a/c, turn the heater on max. That seems to work, at the cost of sweaty clothing.

Thoughts?
