On the baffles, I made mine from scratch from black coroplast sheet, and used zip ties to hold them in place.


Where did you find this space aged material??? I looked on amazon, but there were so many
f'n choices !!!! 4 mil thick, etc ????
I'm going to update my baffles since you had good luck with it.. Mine are still there but not in the best of shape. so i figure I'll try this

This is the stuff I bought: RATIVE Coroplast Correx Poster... https://www.amazon.com/dp/B07BPVP1KB?ref=ppx_pop_mob_ap_share

The only difference between his and mine is that I installed mine in front of the radiator instead of behind it, to promote better sealing. I’m sure either would work just fine.

So you’re saying I could go steal some housing development signs and accomplish this? Lol

Also I thought I blew her up yesterday driving up to Genesee park to return the trailer. On the steepest part we got a flashing check engine light and started losing power quickly. I was able to make it to the side of the road and checked codes. Found cylinder 4 misfire and cleared it. I started it back up and it instantly gave me issues. I shut it down and checked codes again and same thing. I cleared them again and started it up and heard a ticking noise. I thought oh crap….. so I looked around and saw cylinder 4’s plug wire arcing to the header. ‍ So I grabbed some zip ties and pulled it up and away from the header. Cleared the codes one last time and we continued on the road.

I have a 2011 Yukon Denali that had high trans temps when pulling my new trailer. Installed the TruCool and no more trans overheating. Now the engine temps are rising to 225 as soon as I get going down the highway. I thought the higher wattage fans were to be used for in town cooling. Mine are fine in town and cool right down when I get my speed down or get off the highway. What kind of restriction do I need in the radiator hose or should I just purchase a OEM item? I purchased this vehicle a few months ago, didn’t find a trans replacement on the Car Fax but it does have a 2020 sticker on it.
