Dmwelljr, I'd stick with the belt driven water pump, my set up has no water pump fan, just a big noisy electric one (most CFM) in front of the radiator. the radiator is a howe from wh or bgy, I can't remember it's been so long since purchase. I run a 200 degree therm, and a 210 on and 185 off switch for the fan. I live in tucson and this summer, I had no heating problems, just the fan noise. I run these temps for the fuel inj. during max day temp this summer the temp never got higher than 205. the fan runs constant at idle or crawing but goes off when you get the speed up to around 25-30 plus. And that's with no mechanical fan!
