Drawbacks to installing e-fans?

[RMP91]

I'm leaning towards making the conversion, but I am concerned about the engine overheating if the e-fans fail to activate for whatever reason...

Is this a valid drawback to this mod?

Yes. You will have less money in your pocket.

LOL

Really bro all the new cars come with them from the factory now.

Only downside is you will need the bigger altenator. 185amp I think. I am getting ready to convert to them too, but I will be getting a 300amp altenator.

I think they say you will be fine with the 135amp... larger is better though

do it you wont regret it. just make sure that you all the connectors on the relay harness are tight.

Great mod!

to do the e fan mod other than the actual replacing of parts what do you need to do? thought you had to activate pins in the ecu to get the fans to work

My local stealership told me today that they are unable to simply "turn on" the pins. That they computer was not capable of supporting this. Even after arguing with the guy for 10 minutes AND pointing here to this forum for evidence that is in fact possible.

I had mine BB tuned so not a problem for me. However I spoke with 2 GM dealerships here and they both confirmed that they cannot do it. I spoke with the Service managers at both places. The problem is their scan tool can do it, They just dont know how.

Mine swore up and down that this was impossible to do. Said he called their tech line and no one there had ever heard of it being done and also said this mod was unsupportable with my comp.

Justin at BB can do just that if you like Im pretty sure. I think I have seen it on their website. It was much cheaper than the whole tune. May be worth looking at.

Justin can do it for sure, EFI live program is awesome!

 

[ponyexpress976]

Right now I'm looking at mods for mileage improvement. This truck is only going to be used as the kid hauler so a "partial" tune would be appropriate.

 

[YukonXLPerk]

It can be done, even if you have to by-pass your computer.

There are plenty of ways to do it. Do a little more research and find out how.

I love having an electric fan. Its like night and day!

Good luck on the conversion, and please post some picks. I would love to learn how to do it....even though I have no need. Cuz im a nerd

You need to find someone with HPTuners or EFI Live to enable the fan.

look on craigslist for ppl who use efi live or HP tuners in you area..
