Inspection of the Air Compressor

1. Inspect the air compressor intake hoses and connections at the air intake at the air cleaner, the resonator, and the air compressor for physical damage or loose connections. If needed, change the hoses, and/or tighten or replace the connections.
2. Inspect the coolant supply and return lines for tight connections. Tighten the connections and replace the lines and fasteners if needed.
