Where to start with an air problem

[Ralph L. Fullenwider]

Morning John:

Not sure if you have an air drier in your year of Coach. If so, then try
removing the 1/4 inch line from the fitting going into the pressure relief
valve, if air starts to build then the relief valve needs a re build kit.
If no air drier then open the dog house and on the curb side of the CAT
toward the front, you will see your air compressor. Behind the air
compressor is where the air governor is mounted. Check the 2 1/4 rubber
hoses for air leaks there. If nothing found, replacing the governor is no
big thing and the cost should be around $20.00 at any truck repair shop,
for the part. Then check for an air leak on the spring break valve under
the right side of the dash by your knee. Just some ideas for you.

Safe travels,
