quote Originally posted by jrr: I am looking to replace my original 16" Puller coolant fan with an aftermarket high CFM 2000 + fan or just the motor. I have mine out. It does work but I am trying to get the engine cooler since I am in S. Florida. Any suggestions for an easy swap? Would like to keep the same plug if possible.

Hi JRR... just wanted to add a few things.

I used to live in the Plantation / Davie / Cooper City area of South Florida. When I used to drive my Fiero regularly, it ran so cool that the radiator fan would never actually come on. In the dead of summer, I could have the car parked (in the shade) with the engine running, and the car would sit at a cool 180 degrees without the fan turning on. I only say that since I want to emphasize that a larger fan is just a bandaid. If your car is stock, and it's running well, it shouldn't really need a bigger fan.

Check to make sure your under-body coolant lines aren't crimped or bent (shops liked to use them as jack points back in the day because they're morons). If your coolant hasn't been flushed and changed out in a while, I recommend that also.

I use Rodney's lower temp thermostat, which I think Patrick above mentioned. But I also use a 180 degree thermostat in the car, since... yeah, it is South Florida.


I go with a 50/50 mix, and add in a bottle of Redline Water-Wetter (which really does work and is scientifically proven). You want to go with the green stuff. If you go to AutoZone, you'll use the Peak stuff that says it's meant for Older Asian vehicles. They consider 80s American vehicles to be SO incredibly old now that it doesn't even fit in their category... but that's the one that you want to use... especially if you haven't rebuilt the engine and anything on the motor might potentially be original (freeze plugs, some coolant hoses, etc.). The Fiero's cooling system has in some cases, double the capacity of some other cars, so it should run really cool when everything is optimal.

You know, if i'm looking at this image... it almost looks like you could remove the factory fan, and actually modify the shroud to accept the new Proform fan?
