 Subject: Electric fan questions
IP: Logged
Message:
I was thinkin about the electric fan today, and decided I want one too. I was going to get rid of the stock clutch fan and clutch, then mount the fan just a little bit inside the stock fan shroud, where it would be completly surrounded by the shroud. I know which one I want, but don't understand why it needs to be a pusher fan. When your sitting at a stoplight in city traffic, why do you want hot air from the engine compartment being pushed through your cores. Isnt it easier to have the colder air from the outside being SUCKED in through the cores.
IDK, I just get confused on a lot of stuff.

I think it's supposed to be a puller not a pusher... maybe I'm wrong, but that's what I've been thinking. My reasoning...if it were a pusher, it'd have to do a hell of a lot of pushing when you're going 65 mph (let's assume we all drive the speedlimit...lol) down the interstate just to get that air moved.

Ok here is the way this works. If you put a fan in front of your
radiator (just behind the bumper) it is blowing at the
radiator. This is called a pusher fan because it is pushing
outside air at the radiator. If you put a fan behind your radiator
(in your engine compartment) then it is a puller, because it is
pulling outside air through the radiator into the engine
compartment. Pullers are more efficient than pushers when
used as the main fan. Sometimes vehicles have a pusher fan in
addition to a puller. But the puller type fan is the workhorse.
The stock mechanical fan typically found on our vehicles is a
puller.
