My alternator cooling mod.. With Pics.

[futureSVT]

alright ive seen some ducting done before to the intake but i decided to give the alternator some cool air..

I found this air duct hose at orileys. its a gates hose #23848 it sells for 6.48 ish a foot but my local store decided to sell me the full 6 feet for the price of one. :banana:

I had to cut a hole in the plastic divider that goes between the alternator and the wheel well. I think it turned out well. I know the hose looks like its just sitting on the edge but its zipped tied good.

with the left over hose i decided to duct the passenger side but i decided not to let the hose sit right up on the air filter. as i dont want it to throw off the maf counts its about 6-8 inches away..

I know the pics arent great.. ill get some better ones with my camera later

Nice improvisation work.

Doing the same but with my spare brake ducting. I will attach to the HE screen next to my Fluidyne HE as my brake duct provisions in the stock bumper cover are already being used. I'll post pics as well. Using a 4" alt. pulley which has holes in it just like an idler, hoping it runs cooler.

sweet....notice any difference, by chance? or just mainly a preventative safety measure?

I would consider integrating a screen to protect the belt and the alternator. Some serious debris comes through my brake cooling ducts.

Good tip!

op, thanks for the part number! I have been looking for some decent black ducting to do both sides on my car for awhile now. I just didn't want the cheap dryer type duct like they sell at home centers. I'm going to see if my local Napa carries this, since they carry Gates belts, and hoses already.

Let me know if you get a napa listing on that, as there are no orileys around me

Thanks everyone.. i havent yet drove the car and datalogged it but its more of a safety thing since (knock on wood) my alternator is still kickin.

Good idea about the screen ill have to fab something up. Also i put some small holes in the hose at the lowest point in case some water got in. the car isnt my DD and i try not to get stuck driving in the rain..

Came out pretty nice. A few people have done this mod over the past year or so due to the number of alternators failing (in part due to excessive heat). Hopefully yours will give your alternator a nice increase in its life.

Nice job, looks good. Keep us posted on if it made a difference?
