Mercedes Water Pump - Saleri 2722000901

Your modern engine needs a functioning water pump regardless of the make or model. Engines make intense heat, and the water pump is the main component working to keep them cool. Mercedes’ M272 V6 was one of their most popular engines about a decade ago, and they’re a common find on the used market in many models. Replacing the water pump is the best way to prevent overheating, especially if its last replacement date is unknown. 

Mercedes M272 V6 Water Pump Failure

Your Mercedes V6 needs to operate at a safe temperature; otherwise, it’ll experience significant damage. The water pump circulates engine coolant throughout the cooling system, ensuring the engine temperature never exceeds 230 degrees Fahrenheit. Above that, head gaskets can fail, bearings can seize, and cylinders can warp. Preventing that involves ensuring your Mercedes water pump is in good health and replaced on time. Typical Mercedes water pumps will last around 80,000-100,000 miles before needing to be replaced. However, that isn’t always the case. 

Symptoms of a failing Mercedes M272 Water Pump:

• Slow coolant leak, due to coolant leaking from water pump weep hole

• A gradual disappearance of coolant, “low coolant” light on the instrument cluster

• Squeaking/bearing-type rattle from the pump at idle

• Play in water pump pulley

• Overheating condition

Any one of these conditions can mean your water pump is due for replacement as soon as possible, but the best check you can make is a physical one. Shut the vehicle off, wait for it to cool, and remove the belt from the accessory system to closely examine the water pump. Wiggling up or down on the pulley (to determine if the bearings have play) or spinning the water pump by hand can help to determine its bearings’ wear, as a notchy/noisy pump or a pulley wiggling up and down is an indicator of bearing failure. Alternatively, spinning the other accessory system components by hand with the belt removed will help determine if the engine bay rattle is NOT the water pump. Idler pulleys are a common source of bearing noise on the M272 accessory system.

Mercedes M272 V6 Water Pump Replacement

Once you’ve determined that the pump needs to be replaced, you have to grab the correct one for your Mercedes M272. Due to an updated timing cover design, early and late M272 engines use different water pumps. If uncertain whether this part fits your vehicle, enter your VIN into a Mercedes VIN Decoder to locate your M272 Engine Serial Number. Comparing your engine serial to the fitment information on this page will help to determine the right water pump for your vehicle.

This Saleri water pump is for the later, more common, M272 timing cover. Saleri is a Mercedes OEM, so while they didn’t manufacture the original pump, they do provide Mercedes with parts and are a trusted manufacturer. Their Mercedes Engine Water Pump replacement is designed and built to Mercedes’ exact standards, delivering the same performance and reliability at a fraction of the cost of a Genuine replacement pump.
