You might as well give up on your "efans suck" argument Bob, If the new Chevy's have them on their 1500's with towing packages, don't you think they are good enough? Don't you think that if they were not reliable they would have been put on cars for YEARS?

So if my fan clutch gets frozen and my fan runs 24/7 your telling me that my water pump will be fine? Sorry dude. I know a lot of people that will disagree with you on that. Even running properly there is stress on the water pump from the fan. If there wasn't then there would be no power loss when the fan clutch is engaged.

YUP, what do you think the fan clutch does when it get's HOT......not a problem!!! And think about it, the power to run the fan comes from the belt, NOT the water pump!!

Matter of fact, for many, many years, cars and trucks run with a huge metal fan without a clutch at all!!

Chevy......that says a lot!!!! Remember, it was GM that tried to convert a gasoline engine to a diesel!!!

Why doesn't Chevy use a e-fan on their Duramax????? HUH????????

bob your comparing apples to oranges. you should know better.

i have been running a electric fan for over 3 years now on my truck with no problems. even hauled my mustang on a full size car trailer.

i have a superior products shift correction package in my trans and it has a thermo by pass valve that allows fluid to flow through the cooler at all times, my transmission runs at 130 degrees and never gets above 160 on the highway. i have never had a controller or relay/fuse problem.

I never said the power comes from the water pump. It has been proven time after time that a locked up clutch will destroy a water pump. Ask and 2nd gen RX7 guys. Yes I know it locks when its hot but the fan was never meant to run full time.

Yes for many years there was no fan clutch but why all of a sudden is every car with a mechanical fan coming with a clutch? I really don't think you know what your talking about.

For efficiency, not because of water pump failure! Same reason newer vehicles have EFI, instead of carbs, same reason there is electronic ignition instead of points!

Lets see some!!!!


You have to do better than water pump failure!!!!!

All I know (I'm a simple guy) is my testing with my products...(yes I should just get a taurus efan...

efan (transmission temps 210, engine overheating)
stock fan (transmission 165, engine not overheating)

Same conditions..towing 2500-3000 pounds coming off the highway onramp. I take the same path everytime, and I only go 60-65 every time!

Maybe the taurus fan would work, but I'm getting 15mpg and I can't get much better than that right now, I did the elec fan b/c of MPG increase, but I'm not going to sacrifice my engine for it.

I don't think so. It worked perfectly when I wasn't towing a trailer. It just can't keep up with towing.

I was told by several of the 'custom builders' around here not to even try to run an efan on a truck. They said cars...'ok'. 'But a truck, if your going to use it like a truck, leave the cooling stock.'

Just incase anyone missed it...the fan worked PERfECTLY and kept my engine moderately cool (or col enough not to peg the stock gauge), when I WASN"T TOWING.

The minute I put a trailer on and pulled away, the ENGINE started to heat up before the trans.

I would definetly give the taurus fan a try, but I don't want to drop all the $ on it to have it fail..I had about 40 into my efan, wiring it and bolts, etc, just for it to crap out on me!

edit: Maybe it's the HEAT or the altitude. My theory is that it's not broken with the stock fan...so I'm not going to fix it :) But I'd definetly try the taurus one if I could find one cheap enough.

How much did you tow?

How often?

City/Hwy?

Temp/Season/Time of year?

I tow about 3k pounds almost every weekend if not 2x a week

I tow about 10 miles city, 30hwy every time

The last time I overheated it was 94*F, Spring, with about 70% humidity. Nothing CRAZY for a FL day, and I still overheated.

Ricky, I think part of your problem might have been from how you mounted the fan in the shroud with that gap between the fan and it. If you ever reinstall it i think you would be much better off doing it like this guy did.

The last thing I towed something over a long distances with my Ranger was a U-Haul trailer with 2 ATV's on it from Indianapolis, IN to Charlestown, IN (about 140 miles). It was late fall last year.

last summer I pulled a car trailer with a tempo on it from one side of the county to the other. Never got above 190* on the trans temp gauge. That was all city stop and go driving.

The big thing I think is the ambient temp difference. I don't know much about any of that stuff, but in the morning pulling the trailer to the riding spot, I was fine, and pulling it back, it overheated (I pulled back at 4pm, left at 6am).

I checked to make sure it was working still...everything was fine, just couldn't cool properly.

Exactly right! e-fans don't have the cooling capacity of the mechanical fan/clutch assembly, and that's why you won't see an e-fan (only) on Ford, Dodge, or GM diesel pickups!!!

not all e-fans are the same. they are not always better. at another car forum i am on, they look down on e-fans cause they just aren't efficient enough compared to the stock ones. and this is coming from pretty much all the people with highly tuned engines.

I thought about getting one but due to the Texas heat IDK if it would keep up on a hot summer day.

This is a troubleshoot not a report of a problem.


Whats broken: The Electric Cooling Fan control unit’s metal cover may not have the specified corrosion protection. Should this be the case the metal cover will experience an accelerated corrosion process, which may lead to moisture ingress and electrical malfunction.

This is not a problem with electronics. The main reason the problem occurs is because the case rusts then it makes it's way to the electronics. Not the electronics failing on their own.

More troubleshooting.

Why publish articles on troubleshooting a problem, if there wasn't a problem???

Still waiting on your PROOF that a locked up fan clutch destroys water pumps!!!

If you notice there is troubleshooting for mechanical fans too.

Wait all you want. I'll take my time now.

Ambiant temps have nothing to do with it Ricky. I think you have a fan that doesn't have the CFM needed. There are numerous members who run efans that live in teh Arizona desert area.

Bob, diesel and gas engines are 2 totally different things, please stop comparing a gas engines cooling to a diesel engine. Oh BTW, there is kits on the market that are for diesel engines.

You still wont agree that Chevy puts them on their towing package 1500 and 2500; even though a member on TRS said his 2500 Chevy with a towing package came stock with an efan? What an idiot.

Ambient temps have everything to do with it!

If it's 50* out, your efan (with controller) will kick on barely ever, even while your sitting at a light for a couple minutes.

If it's 100 out, your efan WILL be on most the time even when your driving.

That fan is the Jusnes Modified Efan. It supposibly is more than adequate.

I'm not running another efan unless i'm just doing a "review" on a taurus, and if I like it, I'll keep it.

I can't see taking the reliability out...theres no argument there. The efan is WAY less reliable.

Look at beard for example, he was towing a trailer and said he blew a fuse, pegged both gauges...then the hwole fan seized!!!

If my mech fan "locks up", the worst it will do is spin all the time, I can definelty make it home!

YUP, they are different alright! A diesel requires a lot more cooling capacity than a gas, and that's why they don't use an e-fan!! I've explained this to you many times, so you either have a reading comprehension problem, or bad memory retention.......
