I'm looking for an electric fan for my car. I was looking through E-bay and I found this very affordable Procomp kit
http://cgi.ebay.com/ebaymotors/PROCOMP- ... 35a6372a4a

It is a 16" diameter and 2500 cfm fan. I think this is more than enough for a 10:1 SCR engine.

I remember reading about someone running on Procom fan on this forum.

I have several questions:
- does anyone know about this fans? Are they quality products?
- Since my car has the narrow early A body engine bay I'm concern about clearance between the fan and the water pump pulley. All the engines tend to move forward when braking, what do you think should be the safe clearance between water pump pulley and electric fan?
- Now I'm running on stock 38AMP alternator, so it's a must to move up and I was thinking about this:

Do you think this electric fan might do the trick? or should i look for something else?

My limited experience with electric fans would tell me your on the right track here. The electric fan will give you more flow than an engine driven fan, while sitting in traffic. Once your moving at any speed the movement of the car pretty much takes over anyway.
As to spacing. I would use the stock fans spacing from the radiator as a guide. Stands to reason that if the factory fan isn't kissing the radiator, that should be sufficient for water pump/ electric fan spacing.
Alternator from most any A/C equipped Chrysler product should be more than enough output.

The only thing not to like about electric fans is the lack of a proper shroud and mounting arrangement--generally "universal" fans have those silly plastic tab things that hold the fan on. Weak if you ask me. That said, a few hours in a junk yard can usually produce a close match for a shroud or fan. You can fabricate a shroud or adapt an existing shroud as well. Finally, use a temperature sensor that is in the cylinder head and throw away the silly contact sensor that gets jammed into the radiator cooling fins. They make work but they just plain look awful!

Take the time to execute a proper electric fan installation and you won't be disappointed. A case can be made for installing a twin pack fan for reliability's sake.

I have a Procomp electric water pump and have seen some Procomp products. They are inexpensive. They seem well thought out. ......but its not hard to figure out this is not high quality hardware. My waterpump works fine .....but it always leaks a teeny bit.

I ended up mounting my electric fan in front of my rad (early A) to get enough room. There it freewheeled itself to death over a couple of long winters. I never turned it on. The engine side of the rad is very tight.

"ProComp" = another pretend-brand slapped on cheap crap from China by an American marketer. It starts out "only a little bit broken" (see Sandy's leaky water pump) but can probably be made to work OK until it breaks the rest of the way. You can do much better and you don't necessarily have to spend a lot of money to do it. A lot of people have successfully adapted electric fan assemblies from wrecked cars originally equipped with electric fans. The controls can easily be bought aftermarket. Here, for example, is a photo-illustrated method of adapting a cheap, good, and plentiful (in North America) GM electric fan to a Volvo 240 radiator. The principles and techniques are universal (and the size of that fan is worth looking at). And here on the same site is a diagram for an easy-to-put-together electric fan control circuit.

Thanks for your answers here.

Even without seen one in hand, I already know that Procomp is a "wannabe" brand, I know I can do much better here, but since it looked inexpensive ...

If you can point me out some quality electric fan brands that will be a lot of help for me (since I'm from abroad). Right awsay I thought that a 16" fan over 2500 cfm will be plenty enough.
Wich of this fans do you think is worth to buy?

I took some messures and I think that the fan should be mounted in front of the radiator (pusher), an 60amp alternator should be enough, the electrical part should be easy, the only issue is where to mount the temperature sensor ... I need to figure that out.

Thanks again!

I've had the summit branded 16" fan in my truck for the last 6.25 years without any problems........ (got it on a sale too)


If you make it a pusher, make sure you flip the blade over.

And I think you have to reverse wire it too.

Polara1974,

This is the fan that has been in my car the last 4 years. It is very thin and fits fine wired as a puller. The Derale thermostat did not last long, maybe 3 weeks. Check my post on Ted's electrical fan schematic. I added a better and more reliable GM temp sensor, circuit breaker, under the dash light, arming and over ride switches. The schematic is about as simple as I could make it and uses a standard 30-40 amp relay and circuit breaker.
It has worked flawlessly for 4 years since I installed the electrical modifications referenced on the schematic.

With a stock 35 amp alternator it keeps up with out any problems. I know other fans have a much higher current draw and the alternator would not keep up. This particular fan has worked very well with out putting an added strain on the electrical system and cools the radiator and engine very efficiently.

You can click on the red link below my name to check out the pictures.
