Keeping coolant and transmission temps under control when towing in the summer heat

[Tallpaulboise2]

It's audible, but not from inside the truck so it's not as loud as the main cooling fans by any means. I'll pretty much guarantee your Tru-cool will be plenty to keep your trans temps below 230, even towing up a 7% grade for miles, as long as it has good airflow through that lower bumper fascia. It's so much more effective than the factory cooler.

As for pics, if I'm using a computer, I take a screenshot of the image and paste it into my post in the browser. If I''m using my mobile phone, I use the insert picture feature on the forum and select them from my camera roll.

Please do keep us posted on what you learn!

flip the fan the right direction there is a arrow showing which direction the airflow should go

I was holding it the right way while I was blowing into it

at low intermittent speed mine gives goofy readings and/or if it is turned the wrong direction. I thought that was the reading you had off of your fans
I checked mine again and it still gives me high 2300's, on the ac vent in the truck I get about 1500 or so

I'll try it on the actual fans tomorrow. It's too late to be messing with it tonight.

Just curious though, where did you get the 10.76 square feet figure to use for the duct area?

lol, it's a magical number I have no idea, must have just created it when I turned it on the first time
if my math is correct then it should be around 4.35 (34"=2.83 X 18.5"=1.54)

Great information in here. Thankfully my PPV has zero towing duties, highest trans temp I hit was 151* while running it hard. Running up through the mountains last month it was running between 111-129*

I have the Trucooler 40k after the OEM transcooler, B&M deep pan (2 extra qts) and a Circle D 3200 billet stall converter.

I'm looking at upgrading the radiator to the Mishi and doing the cooling fan upgrade; I careless about noise.

So what I have read (all 25 pages) for the fan upgrade for a non RPO K5L I will need the following parts to swap the drivers side fan?:

2090 3474 - fan motor
2089 7351 - fan blade

Sounds like you and I are in the same boat with a few of our upgrades. Do we get a BB Tune combo deal? Ha!

I'm already tuned but I need to get a refresh

Honestly my only reason for doing this is in hopes to get/keep that AC nice and cold. My alternator is near its life expectancy so I might as well do that when I'm in there.

How are the belts and water pump?

Have you added Pag Oil to the a/c compressor and/or bumped the Freon?

I’m on my iPad on a plane so those part links aren’t working for me, but as long at you have the correct motors and fan blades for your year of truck, per a good parts configurator, then that’s probably right. There are different part numbers for the 700w motors and fans for my 2007 vs my 2012, so the parts I listed were for a 2012.
