I'm running a 14 inch hayden i got at the local oriellys works great no problems on my end and it fits great on the engine side of the rad

im running a probe fan

Ive seen quite a few people on s10forum use ford taurus fans, not sure how big they are though.

flex-a-lite 13 inch pull thru.works great.bj

im only running a b1800 and i have a fan out of a sprint.. and rad for that matter.. old rad wouldnt fit through the fram like i needed.. ran a cooler thermostate and away we go. i simpply hooked it up to a hidden switch that also controls my fuel pump for security reasons...

would something like this work?
or

think im going to go with this one...
