Electric Fans... push or pull??

OK... now I've gone through the search engine and read a good deal on the Electric fans.

My question is, what's best, a pusher fan or a puller fan? I've read that at hwy speeds the pusher fan can stall out, I've also read that the fan should cover the entire radiator surface...

I have a A/C auxilary fan that is a pusher that I was intending to mount at the front of the sami's radiator... now I'm begining to think that it may not do the job.

I've got a 16v engine with a new 3-pass radiator. Any helps??

Re: Electric Fans... push or pull??

maybe i'm thick, but what are you calling a pusher fan? a fan mounted in front of the rad pushing air backwards through it? if so, how would that stall out at highway speeds? moving air would only make it turn faster. or if you mean a fan that's turning the wrong direction, that's a bad idea in my opinion. two friends wired their fans to turn the wrong direction and both bought new rads soon thereafter (dodge rads are part plastic, and they exploded during overheating)

Re: Electric Fans... push or pull??

The AC booster fans are just that, boosters. You need a fan designed to pull or push enough air to
flow and cool the rad. If you get a good puller fan you could also run the AC pusher, but the AC
fan by itself is not enough.

Re: Electric Fans... push or pull??

I believe that a puller is more efficient than a pusher fan. Check out the FAQ at Flex-a-Lite's site.....

Re: Electric Fans... push or pull??

Thanks Crow...

That's what I was looking for.

Did you remove your OE fan & clutch in favor of this 110 model?

What's your evaluation of the product?

Do you have it set up to the temp sensor so that it cycles automatically?

TIA

Re: Electric Fans... push or pull??

I run ac fan out af a 5th gen civic... I never had a heating problem once. Covers the radiator nicely and fits like it was meant to be there. I dont think that this is just a booster... you have to dissapate more heat when AC is on... I wouldn't put a fan this size in a 502 caddy... but it works perfectly in the Sammy. And the can be gotten easily for 5-15 bucks...

Re: Electric Fans... push or pull??

i run a puller electric fan on my good zuk. never had a cooling issue. i am using the universal mount version made for v-8 engines. the same fan kept my friend's amc 304 cool too.

most common cooling issues up here are corroded or pluged radiators. i went with the electric fan because i run a gti bottom end and gti water pumps are not made to mount a fan clutch to them.

Re: Electric Fans... push or pull??

Are you having overheating problems using the stock fan? A 16v engine should cool fine with the stock 1.3 radiator and fan unless there's a problem or the air flow is being blocked.

No... that's not what I'm after... I'm looking to gain that extra hp &amp; mpg's...

My personal goal is to get somewhere around the 120hp mark outta the 16v without a whole lot of mods to the engine. I'm thinking that the port &amp; polish with the high flow 2" exhaust system, K&amp;N filter along with the aux fan should get me purdy darn close. If that doesn't do it, Schneider cams is right down the street from work... maybe I can get them to grind one. [img]images/graemlins/laugh.gif[/img]
