Operate the engine to activate the air compressor.

With the air compressor pumping between 550 to 690 kPa [80 to 100 psi], use a solution of soapy water to check for air leaks in the following areas:

  • Air compressor head gasket
  • Air compressor cover gasket
  • Hose and fitting leaks.

If air leaks are found, verify that the air compressor head and cover bolts are torqued properly. Make sure hoses and fittings are tight. Replace if necessary.
