(cont)Step 4.Check for poor compressor cooling (compressor runs hot). Check coolant flow and temperature throughcompressor. Install suitable flow meter and temperature gage between compressor coolant outlet andengine block (Figure 6-1). Start engine. Flow through compressor should be at least 2.5 gpm. Coolanttemperature should not exceed 200 degrees F. Stop engine.If flow is not at least 2.5 gpm, check coolant lines and fittings for scales, kinks or restrictions. If coolanttemperature exceeds 200 degrees F., refer to Cooling System Troubleshooting.Step 5. Check air system reservoir for build-up of dirt and water.Drain reservoir. Refer to TM 5-3805-261-10.Step 6. Check if air compressor runs loaded an excessive amount of time. Measure air system leakage. Installsuitable air pressure gage in air system (Figure 6-1). Start engine and let air pressure build up andstabilize. Observe air pressure gage. System leakage should not exceed 1 psi pressure drop per minutewithout brakes applied and 3 psi pressure drop with brakes applied. If leakage is excessive, look forsystem leaks. Stop engine.Repair system leaks, if necessary. Refer to paragraphs 6-9 and 6-11.Figure 6-1.6-3
