Hoses

The top radiator hose carries coolant to the radiator for cooling.

The bottom radiator hose returns the cooled fluid to the water pump, through the thermostat, and then into the engine.

The bypass hose transports cooled fluid directly from the water pump to the engine, bypassing the thermostat.

The heater hose circulates hot coolant to the passenger compartment heating system.

Serpentine Belt

Your Mercedes’s systems may be controlled by a series of v-belts or a single serpentine belt.

These belts power the water pump, alternator, cooling fans, and power steering system.

A belt failure would almost certainly cause the vehicle to break down, and repairs could be costly.

Visually inspect these belts for splits or cracks, excess grease or a glazed appearance, and wear or damage along the edges.

Also listen for a squealing noise, especially during acceleration.

Timing Belt

The timing belt is responsible for keeping the camshaft and crankshaft synced up.

A failure will likely cause major engine damage, which may require a full engine replacement.

The timing belt must be replaced as scheduled by the manufacturer due to natural degradation over time.
