My dash gauge is extremely accurate between the 170 and 210 mark compared with my V2, the temperature will drop from 200 exiting the freeway and by the time I stop it will be at 180 degrees in less than one minute...
Quote:
The Chevrolet LBZ trucks block a good majority of airflow to the radiator and blocks the transmission cooler completely.
I enlarged the holes at the bumper, removed some tabs on the bumper and frame horn massaged the plastic liner in the picture below and a new transmission cooler.
At idle the AC works better and hovers per my V2 180-185 degrees sitting still and the dash gauge doesn't peg the 210 mark on the freeway and drops 20 degrees after exiting the freeway, the transmission stays at 150 degrees so far, I'll know more in August if it was worth-the-while...

As soon as I come up with a way to trim the plastic cover I'm gonna cut some a holes in the 2" body/bumper raise that blocks direct flow to the transmission cooler (Found that idea on DieselPlace)..., or rotate it 180 degrees...

I removed part of the tab at the bumper and frame horn and heated and massaged the plastic panel down. I'm going to replace the stock bottom panel with some Coroplast and make some vertical panels also. If I sell some more equipment to pay for my medical bills I'll embezzle a little bit of it for some fender vents to allow more air to escape from the dog house......
See the horizontal bar just below the cooler, it has holes in it but still blocks about the lower 2" of the radiator and no air flow makes it to the extreme right or left sides. After removing the tabs at the bumper and frame horn I can place a flat panel all the way across.....

Found a good example of how much the bumper blocks the stack or the transmission cooler.
