Dirt track Pontiacs are tough to cool, but this fan was recommended to me by the shop owner that I used to send all my radiator work to. I tried one, and was sold. Another nice thing is they are much lighter than a fan clutch assembly so easier of water pump bearings also. They aren't going to get you any fuel mileage improvements, but keeping the engine cool trumps fuel mileage. |
Oh wow, that's excellent, and that nylon fan is pretty cheap so it's definitely worth a try. I did a bit of poking around and I see that there is another one that is a re-branded version of the Flexa lite for a few bucks less and is called: Allstar Performance ALL30095. I think i will pick one up just to see how it compares to the Derale. Thanks for the tip!
