Help me understand which cooler is which

Nathan79 · October 28, 2015

I recently purchased a new 2015 Sierra 2500 with the 6.0. I've been poking around the hood, seeing the differences between my previous 5.3. Are there any diagrams that show which front cooler is which? I'm going to assume the one in the front, on the bottom by the license plate and open to the air flow is the ATF cooler? How about the one just above it that is black with what looks like wire loops coming out of the tubes? Oil cooler, PS cooler,....

Just trying to learn what is what.

The loofa/sponge looking one is the power steering. Transmission aux. cooler is the one you can see right through the bumper opening. Behind that is the condenser, then the radiator. Engine oil cooler is on the left side of the radiator assembly. Transmission flows through the main radiator then to the aux. cooler.

Thanks! That's what I wanted to know.
