My 1st try was wired correct. It was a cheap fan off of eBay ($54.00) THEY said it was a 3000 cfm but I have my doubts. It's was installed directly to the radiator and with the stock shroud.

The new one has a adjustable thermostat so it might be that the old one was backing up the air on the freeway, ( going slower than the air coming in) because it never turned off as far as I could tell.

Another member had good luck with this fan set up curing his over heating also but he had a relay go out a year later and went to the updated stock set up. But it was noisy.
