How are the belts and water pump?

Have you added Pag Oil to the a/c compressor and/or bumped the Freon?
I had the AC system serviced back in the spring, I think I have a grounding issue someplace I'm also trying to track down.

I have dye in the system, I just need to get under the UV light and check for leaks.

Picked up my trailer from servicing and headed for the freeway. 97 degrees outside. After 12 miles of driving over moderate hills the trans temp hit 185. Then I looked at my engine temp and it was 230.
I turned around to head home and had to get off the freeway because of an accident. I had 25 minutes of stop and go traffic and the temp hit 201 once. The trans temp problem is looking good but now I have to diagnose the high coolant Temps. I know the drivers side fan has a high speed but does the passenger side fan step up also? I have never heard it. I think I need to go back and check the threads for info on my fans.
Looking at your photos (# D48AC) what did you use for “standoffs” and the other hardware on the top mount of the cooler where it connects to the frame?
You guys have got me all ***kerd’ up with the cooler adjustment down to the lower grille. I’m prob going to fab new mounts and buy hardware for the lower grille area just in case.

I never even had a lower grill option. ‍♂️
Thinking I'm going to try and put it horizontal (parallel with the ground) between the bumper and "skid plate"

I used some of those metal spring loaded Y adapters like you would use for drywall, the sleeve's were just some misc metal pieces I had in my junk cabinet, I think I used 3/8" and had to throw on a couple washers so the bolt would not bottom outPXL_20210703_032531398.jpg

If the truck has the K5L code it’s the 700w motors. If not it’s the 500.
In the middle of putting everything back together with the new water pump, just check the glove box, I do have k5l. I guess I don't need to worry about the motors.
But I do only have the five blade fans. Are the seven or nine rimmed blades better?

The ones you have now are just fine and not worth changing out

I cut some EMT at an angle so the cooler bracket would sit flush to the spacer. 3/8” toggle bolts and washers hold everything together. Someone mentioned they used hinges on their Derale install. I think that was a good idea and would have done that also if I had read it before I started.
