electric fan???

found this from another tacoma owner thinking of doing this.

 

Your stock fan doesn't work?

 

frees up a little power

 

^^^^ which would be really good for the 2.7

 

Here's a link to the electric fan DIY writeup:

i like electric fans. not so much for the power gain...there really isn't that much, but it makes the engine run a little less noisey

it also free's up space at the front of the engine which allows easy access to accessories. plus belts are easier to change.

my expierience was on an older chevy small block.

 

Had one on the 82 when it was a lowered convertible street machine.

 

You don't even need the shroud but it helps brace the fan if you do it right. DO IT. It makes a huge difference on the 2.7L.

 

Why would you not need the shroud? It's essential to ensure it pulls air through the radiator at stopped/slow speeds.

Anyway, I've thought about doing it myself. Cleaner, easier to work with, don't run the risk of burning the fan clutch out and getting stranded on the side of the road, and it's safer to work around.

 

you run the risk of bad wiring. my wire burned or broke did something. anyways...it highway speed, it didn't need the fan to keep cool. at a stop tho, the temp would shoot right up and i could only stay stopped for a couple of minutes

as for a big shroud, it's really that important, since the can comes semi shrouded. anything more than what comes with the fan isn't going to help much, or really be needed.

i was running the flexalite dual fan set up.

 

I put the Flex-a-lite kit on mine (bring $$$$$), mostly to try and help the AC system. I didn't notice any performance or milage gains, but start-up is sure quiet!

 

The one thing I don't like the flex-a-light fan is how the shround is smaller then the stock one. It looks so weird the way they designed it.

 

Keep the hood closed...

 

I want to put one on my 1st gen it makes a decent differnce in mpgs and helps with power a little.

 

Well the flexlight has a built in shroud. I thought you ment just attach an electric fan to it.... with no shroud. It would do very little. For example:


At speed, it's fine. Idle or traffic, I got it up to near 240F (sbc v8). Yea, that was bad... had to stop in downtown Portland (was only about 85F out) and let it cool for about an hour. Also, the transmission cooler has been relocated to the front since that pic so... in before someone notices I still need to fix the fan/shroud bit though...

 

what is that in? that's an big shroud. i was running a dual fan set up and the whole thing was only a an inch or two think.

i'm suprised it couldn't keep it cool at idle unless the air flow rating was too low

 

I'm thinking about doing this to mine, but I'm a little concerned about the heat problems described by kyouto42. Is that a result of the shroud mismatch, or more of a fundamental problem with electrics in Tacoma's? Maybe a low cfm fan problem?

 

Not sure if you were directing this at the Flex-a-lite kit, or the home fabbed one, but my Tacoma with Flex-a-lite kit has not had any cooling problem since it was installed last August.

 

Does anyone have any data to show what gains there are from this mod?

 

Besides post 11? Not the detail data you wanted, but it is my data.
