I need some help identifying what these two coolers are, the photo might be side ways. But I took the photo from under the truck facing up so the one that's really damaged is the driver's side. I'm not sure what they are whether Transmission, A/C?

Hi,

The one on the right appears to be the power steering fluid cooler. Is it leaking?

If you look below, I attached the directions for replacing it. When you do this, closely inspect all the other PS lines/hoses. They can rust in spots and fail.

Just fyi: The transmission is cooled via the radiator. On the passenger side, you will see two steel lines going into the radiator tank.

The other cooler on the left of your picture appears to be an engine oil cooler.

I hope this helps. Let me know if you have other questions or if there is anything I can do to help.

Take care,

Joe

Hello,

The one on the left is the auxiliary transmission cooler and the one on the right is the power steering cooler.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
