Froozen up.

Is it the air dryer or a main line freeze up? Is the air noise coming from compressor or dryer? You could Take the supply line off the compressor and fill it with air line anti freeze. Then put the line back on and start it up.

Might not be the best way, but you don't have many options.

 

When was the last time the air dryer dessicant was changed?

 

Leave it run till the engine builds some heat, sometimes the valves in the comp stick, I just dealt with this issue last week at -35*C

 

You can destroy the air compressor if there is ice in the lines. Pull the main line off on both ends to see if there is ice in the line. Then add air line antifreeze into the air compressor end of the line after hooking air tank end up first. Then I would use a hair dryer to around check valves to wet tank to ensure if the valves are frozen they will thaw out. Then hook up the air compressor line and start truck.

 

He is probably hearing the pressure protection valve on compressor poping off. The airdryer is probably froze up and the heater element is bad. The airline antifeeze will work. I knew a guy once that couldn't get any airline antifreeze he was in the middle of nowhere he used jack danials and it worked. Nucessity is the mother of all inventions.

 

yep works on all of them trucks .

 

i wonder where the guy got a bottle of jack in the middle of nowhere..lol

 

Is there a intake and outtake on the compressor? which one should I put brake antifreeze in? How to find which is in or out?

Thank you
