The MB Express Repair team is highly trained in truck cooling system maintenance. The cooling system works by constantly passing coolant through channels in the engine block. Coolant, driven by a water pump, is pushed through the cylinder block. As the solution passes through these channels, it absorbs heat from the engine. This cooled coolant then flows back to the radiator, where it is cooled by the airflow passing through the radiator fins. MB Express Repair can service your truck's cooling system and keep your engine running at its best.
