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

[Doubeleive]

So far Dropping the Tru cool to the lower grill area there are holes on the inside back of the front bumper and they line up pretty well with the Tru cool mounting tabs, so do the 2 top bolts of the splash guard/skid plate, I just need some 1 1/2" metal to make the last 2 brackets

as long as I don't run over anymore stop signs I should be fine

Some progress, not exactly happy with this so far but not many other options

I wanted to check the cfm of both the 7/9 rimmed 700w and dual 5 blade 700w to see which one moves more air (or if they are the same), I don't care about the noise I have a nice stereo to turn up lol

I really can't hear the fans that much from inside, but from outside they are loud.

I might get one if those anemometers and see what mine fans do.

Decided to leave a piece in the center for support

I made a 500 mile trip on Sunday, I have the tru-cool mounted in front of the radiator as pictured above, since my transmission was rebuilt with extra clutches and etc, it seems to run a bit warmer than it used to, at 7-8000ft elevation and 90deg's ambient, ac going and moving at about 75-80mph transmission heated up to 193, that was not the issue, the issue is this made the coolant heat up to 230deg. turning the ac off seemed to help a smidge and coolant temps were then up and down to around 220-225, so I am planning on moving the tru-cool down to the bottom grill and doing like others have and opening up the lower grill holes, just have to figure out some kind of mount. not sure how much air flow it will get at that lower grill or if will effect any other cooling I am thinking probably not because the lower part is below the center of the bumper cover that should be splitting the air 50/50? up/down

Just add a bottle of DEI radiator relief or run Evans waterless coolant.

I am 99.99% sure it is only because of the tru-cool being in front of both the ac condenser and radiator, I almost have it all back together I just have to go grab a new ambient temp sensor when I went to move mine back where it should be the plastic clip is all brittle and broke, $6 part so may as well just replace it.

All wrapped up, test drive around the area trans ran about 150, after I warmed it up real good and let it sit and idle it sat at 165 with no fan, its about 95degs outside

Better turn that top righthand bolt in on the bracket, if you haven't already.

The original bolt was stripped they strip easily so I just stuck a larger bolt in it for now I need to find a shorter one

That’s where I got my hood louvers. I didn’t see anything like that, but will look again.

thanks

Awesome!

I searched eBay backwards and forwards for skid plates a while back and only came up with factory Z71 ($$$$) or one from RCI meant to pair with their 6” lift.

This set up is so much better than in front of the AC condenser/radiator.

hopefully, I haven't had chance to really see how it does yet. might be taking a little road trip in another week or so which would put me thru some mountains about 6500 feet

Looking forward to you observations after the road trip. How was the coolant temp during your test drive? My trans temps have been low after the tru cool but coolant creeps up to 230 on big grades; we have a lot of those here in Idaho. I’m going to drop mine this weekend. Nothing else to do since it’s going to be 105 outside.

Do you have a fan behind the newly relocated trans cooler? What do the temps get like when you're sitting in traffic, or just idling through a drive thru?

no fan, just idling a bit and driving slow in the local area it hung around 165 this afternoon and it was probably 90 deg ambient, I haven't even put 5 miles on it yet like this so hard to say what it's going to do, I drove it up and down the road yesterday to heat it up and it idled around 165 as well. When I get a chance I will try and give it a good work out and report back, maybe tomorrow or tuesday
