GMC Power Steering Cooler
Received the unit from Kansas. The box that it arrived in was crushed at one end. The unit appeared to be OK. Unit should have been put in another box to protect the item inside the original carton. The carton had pieces of foam around the cooler to keep the unit from floating in the box but no other paper or material to keep the box from crushing.

Not that I know of but YouTube could be a good bet.
Richard S October 19, 2017
Yes there is. But it doesnt go into a hole lot of detail. Youll find the video on YouTube like I have. Once I found the video I followed what o could get out of it, and did the work my self it was very easy to do, and I had no difficulty what so ever. Once you see how to do the work needed you shouldnt have any issues. Take care and best of luck. Sincerely Jimmy.
