I added the water wetter. It might have helped a little. I have used it on most of my cars.

It cools great while running down the road, (yesterday it was at 168 deg) but when you stop it's another story.

You have that fan wired in the "High" mode only? I might wire this thing to a switch and run it when I need it in the warmer months. Up until this month I haven't had such high temps.

I found a Mr. Gasket # 1988 on Summit that is reversible. It pushes 2000cfm and should make a good pusher if it'll fit.
