GM 2.7L Engine Notice
The GM 2.7L Gas Engine has a new Active Thermal Management Cooling System that controls the
coolant temperature and flow with an Engine Control Module (ECM). As a result, there is no coolant
flow available for the Bowie mobile clinics to tap into to provide heat for the water system and day
heater. If the unit is installed in a GM truck with the 2.7L gas engine, you will not be able to get coolant
flow to the unit, and there will be no hot water, or heat in the unit.
Bowie is evaluating solutions using electricity, rather than coolant, to provide heat for the water system
and day heater. We will provide updates as things progress.
