trimster Posted December 31, 2015 Report Share Posted December 31, 2015 On my Int. 4800 dt466, I don't have air pressure. The truck has been setting for 2 weeks, block heater plugged in, but it's been cold here in Utah. Teens most nights, 32 during the day. Fired it up and let it idle for 20+ min. Air pressure gauge says '0'. Where do I start looking, tinkering, to get this fixed? I can't drive it because the frame drops onto the top of the rear tires with no system pressure. I could jack it up and put blocks back there to keep the frame a few inches off the tires if needs be, for an emergency run to a shop. Where is the air compressor located on this engine?

skp51443 Posted December 31, 2015 Report Share Posted December 31, 2015 The air compressor should be on the driver's side bottom, front of the engine. You may well have ice in your air lines or tank which is an easy fix, having the compressor die is a lot less likely. If you didn't have antifreeze in the coolant it could have cracked though, it doesn't see a lot of heat from the block heater. You can crack the fitting at the pump to air line connection and check to see if you are getting air out, if you are it is likely ice. Melting it out if it is in a line is easy with a hair dryer, just toast any low spots and see if you make air. If it is in the tank it takes a bit more time and heat, a 1500 watt heater under the tank and maybe a bit of wind-break should do the trick in a couple hours. Worst case grab the AC air compressor and use it to run your tank up to 120 PSI and that should be good to drive several miles as long as you have hydraulic brakes.

trimster Posted January 1, 2016 Author Report Share Posted January 1, 2016 Thanks and happy new year. It's a toasty 3 degrees here in Utah. I have one of those 50,000 btu blaster heaters I use to heat the garage. I'll put that under the truck aimed to the back and let it blast away for a while. Got to love the cold weather...NOT.

trimster Posted January 1, 2016 Author Report Share Posted January 1, 2016 Success! Put the big blaster under the front aimed back for 30 min. Fired the truck up and captain, we have pressure. Pulled the tank drain valve a bunch of time to blow out water from there and the lines leading to it. Pushed the bag dump for the rear to clean that out a bit. So it's a toasty 17 degrees and life is good.

skp51443 Posted January 1, 2016 Report Share Posted January 1, 2016 Good to hear the cheap fix was all it took! We learned to dump the air daily in cold weather, only takes a moment if you have an electric dump or a pull-cable on your dump valve so you don't have to get under the truck.
