The vehicle was due for preventive maintenance and was also losing coolant near the engine block-heater location.
Inspection confirmed leakage at the block heater while the planned fuel-filter and rear differential services were being completed.
SnapFix replaced the diesel fuel filter, exchanged the rear differential fluid, and serviced the leaking block-heater area to address the coolant loss.
The vehicle received its scheduled maintenance and the discovered coolant-leak source was addressed during the same mobile-service appointment.
