OM642 Oil Cooler Leak: The Basics
If you own a Sprinter manufactured sometime between 2007 and 2010, it’s fairly likely you’ll encounter a leak with the oil cooler unit. Oil coolers are typical of machines that are intended for heavy usage. You may not find them on standard production automobiles, but in the case of a Sprinter diesel van, a vehicle that generates an exceptional amount of heat, they’re there to prevent damage to your engine.
Many Sprinter models from 2007 through 2010 were equipped with a Mercedes-Benz BlueTEC OM642 V6 diesel engine, a model that was outfitted with faulty oil cooler seals. The rubber that these seals were manufactured from degraded quickly, causing oil to escape the unit and spread throughout the engine bay.
As you can imagine, this issue is not only problematic due to the loss of oil your vehicle experiences, but also because of possible damages to your car from oil seepage. This problematic OM642 oil cooler unit is located in a hard-to-access area of your engine bay, so we recommend you entrust the repairs to a professional who is experienced in Mercedes-Benz repairs. Taking your Sprinter to a non-Mercedes mechanic runs the risk of misdiagnosis and repairing parts that may not necessarily need repair.
Though the Sprinter oil cooler leak repair cost isn’t insignificant, it’s worthwhile for a number of reasons. First, the Viton replacement seals your OM642 will be equipped with will ensure oil retention far better than their faulty counterparts. Next, you’ll help prevent premature breakdown for your Sprinter van, especially if it’s used frequently for business purposes. Finally, you’ll help extend the life of your Sprinter van, obtaining better value from it in the long run.
