Cooling system
To prevent carbon build-up on the turbine shaft in the turbocharger, an auxiliary water pump provides
additional water circulation for up to 15 minutes after the hot engine is shut off. The pump transports the
lower-temperature coolant against the direction of flow. The coolant, which is taken in by the auxiliary water
pump, flows from the radiator through the turbocharger to the engine block and back to the cooler to
dissipate stored heat.
