Air Compressor Discharge Line

I have a Volvo D13. I don't own it. I just drive it. Does anyone by any chance have a picture of where the discharge line is connected to the compressor? Or maybe an idea of how I can spot it?

• For many years I've been pouring air line anti freeze into the glad hand between the tractor and the trailer but the alcohol seems to mess the grommets up. I was recently told that the ideal place is to take the line off the compressor and dump 1/2 cup in there. Is this true? And if so can you give me an idea of where this line is at?

I'm told that the best place to put your airline antifreeze is in the line that's going from the compressor to the air tank.

 

Man..... thankyou so much for all of that! I'm glad that I asked before turning a wrench. Makes a lot of sense, for sure.

 

Thanks. It sounds like from another member that I don't want to pour it in there anyway. Looks like I'll be pouring it in between the air dryer and the air tank on the tractor.

 

Roger that. Thankyou

 

I recently learned that I should put it past the air dryer between the air dryer and the air tank on the tractor. But thanks anyway.
