What to do if my HydraMaster CTS 403 Flex Cleaning Equipment engine overheats?
- BBrittney FarleyAug 23, 2025
If your HydraMaster Cleaning Equipment engine overheats, several factors could be the cause. First, ensure proper ventilation by opening all van doors or installing a roof vent. Remove any dividers or objects impeding airflow around the truckmount. Check the oil level and fill as necessary, as low oil can severely damage the engine and require inspection by a technician. Verify the engine RPM and adjust it to 3,150 RPM under a vacuum load of 0” Hg if it's too high. Inspect the heat exchanger for blockages, cleaning or replacing it if necessary.
