Is there a break in time on the new fan clutch? I never liked the noise my fan made while I was driving.
I jumped on the E-fan bandwagon and I have only had one regret. Not getting a better battery first.

Just thought I'd toss in my $ .02

 

Get an electric fan from a late 80's camarom very easy swap and works great. Some of the after market clutches disengage the clutch at different rpm;s

I would actually prefer to go with an electric fan if I can. I was looking at electric fan kits at several different auto stores and all of them recommend these fans as a secondary cooling fan but not for use as a primary. If I knew exactly what to get, perhaps I'd join you on that E-fan bandwagon.

992drjimmy,

If I knew exactly what to get I would.

I'd need a list of components and are these electric conversion able to keep the engine well cooled?

Thanks again.

 

Do a search for e-fan and there is a long but very informative thread about it. You can fab your own set up, or U can but a ready made kit.

Would you happen to know the link? I did a search but it was pretty long and most of what I got was people using fans from 80's camaros and ford taurus's. Not much about installing though. I'll keep looking.

thanks

Edit: my tauaus fan keeps my motor cooled on 90* days on the low speed in traffic no problem. Voltage drops at idle though, some of the kits like the flexalite and permacool pull less amps than the tauraus fan.

 

I've been fighting for days to get my 2000 S10 4.3 fan clutch off.
I even rented a removal kit from Autozone but i don't think they gave me the proper tools...the guy even said when i brought it back that they always have issues with GM removal tools there...

I got a 15 inch cresent...that can grab the bolt pretty good...
And i tried to use 1/8 alum bar stock and drill a hole in it and put a pully bolt through it and brace it with the frame from the bottom when i turn the clutch bolt clockwise...and the bar stock bent...and ripped the aluminum at the bolt...
I'm catching hell on this thing...
I looked at the HTML provided above...and it didn't show me how to get that friggin thing off....just said he used a 13mm wrench braced and it wasn't a good idea...( can see why ) any other tricks anybody knows?

help!

 

I usualy use a large cressent wrench, and i try to wedge a screwdriver on the small bolts that hold the pulley on. Leave the belt on the vehicle. Or use a strap wrench to hold the waterpump pulley.

Make sure you are turning it the right way too. I think it is standard threads(counter clockwise to get it off). It should come off if you turn it in the direction that it turns normaly when the engine is on.

 

I use a 1 7/16" end wrench to remove the fan clutch from the waterpump. Don't try to muscle it loose. Use a BFH and whack it. A couple judicious hits and it should break loose. Then it will spin off by hand.

I ended up buying a really long blade for my sawzall and hacked the thing off. It only took about 60 seconds but I had to by a new fan clutch which is what lead me here. Now the new one is noisy and working too much..

Im still looking in to the electric conversion. I'll probably go that way once I have all of the information and am satisfied that I can make it look professional and feel confident it will be reliable. I have no intentions on ever selling the truck.

Now I like the sound of that.

 

Here is the original thread from the S-10CREWCAB.COM - LT1 Electric Cooling Fans

For those who do not feel comfortable with the modifications required , or unable to find a used fan set-
Flex-a-lite website

Flex-a-lite #210 Dual 12" fans with control-$235.88

Low profile, big output.

Flex-a-lite low-profile electric fans have the lowest profile available, yet flow up to 2,500 cfm. They have lightweight nylon shrouds with full-contact rubber seals, and some even offer several choices of shroud color. There's also an optional, adjustable thermostat and air conditioning relay, as well as a manual override switch to shut down the fan for mud racing or water crossings. A wiring diagram and installation instructions in English, Spanish, and French are included.

There are a couple people using this fan set for the increased clearances, and all in one "kit" appeal. I guess it works, since one of those guys is running an LS1.

 

crap.......double post...next one better stated....

Check!
15 inch cressent in hand.

Make sure you are turning it the right way too. I think it is standard threads(counter clockwise to get it off). It should come off if you turn it in the direction that it turns normaly when the engine is on.

You sure?
I have read a few places its backwards threaded .... to turn it clockwise to get the nut off....
Can anybody clear this up for me? (although what you said makes sense) looks like i've been trying to turn the damn thing the wrong way if so........which would be a relief actually.

The Chevys with the serpentine belt have a reverse rotation water pump. The nut is turned counter clock wise while facing the waterpump. "Lefty Loosey" . It is right hand threads. Standard threaded.

It will be seated tightly. Give the wrench a whack to break it loose. No amount of muscle will push it loose easily.

Ford's do use left hand threads and turn off the wrong way.

ya....found that before i posted...
But...it didn't tell me which way to turn it...and how to brace the pulley....
And since i was under the assumption that I had to turn wrong and brace pulley.....i was doing the ass clown dance....that thread told me neither...(now I know why)

 

When you get the system filled up loosen the radiator cap, or flip the lever if you have one. Squeeze the upper radiator hose to purge the air to the expansion tank. Do this several times.
Make sure that the expansion tank is filled to the full hot mark, and check the level after a good warm-up cool down cycle.

Good luck

 

i updated the picture to show that, thanx for letting me know

Nice... Much appreciated.

 

I appreciate the info. Looks like I will go with the E-Fan kit. Most likely the flex-a-lite kit as I would prefer to have a new setup. I think i'll throw in a secondary bypass switch just in case.

Thanks for all of the posts.

 

where do i put the sensor in the radiator?

which hose is the input hose?

Directions say put it very close in the radiator fins to the input.
