97 Ch613 Coolant Leak

[msbulldog601]

My 97 Ch613 is leaking coolant I see it on the ground looked around and saw this threaded line wet and I’m sure it’s coolant that I see on the line. Can anyone identify this line for me so I can replace it? Thanks!

Yes you will. You need to drain the radiator be starting to replace the line

I think when I did mine I just disconnected that line from the compressor first and aimed it into a large catch pan and let it drain out that way until it stopped. Then disconnected the hose from the side of the block. It took a few minutes but this way I didn't have to drain out any more than I needed to. This was on a 94 RD. If I remember right the radiator drain / lower hose is still a good bit lower than where that hose runs into the block. Either way will work though.

Yep, there is a port on the compressor head, top right outer side, on a Bendix. Some of them have a 90 degree drain spout, takes a 9/16" deep socket to open it..  I think about 3-4 gallons is all that will drain.  Easy to do..
