**NEW PURPLE VITON VERSION**
Oil cooler seal for the oil cooler on the OM642 motor. Engines built before 2010 used a non-viton, orange seal that starts leaking after just 50,000 miles. This new version, which is purple and is a viton material, holds up much longer.
Replacement of these seals can take 10+ hours, so be sure to use this new version of the seal so you don't have to do it again! Replacing this seal requires removing many components on the engine, which each have seals of their own that must be replaced. We strongly recomment purchasing the full OM642 Oil Cooler Seal Kit instead of the individual seals.
Fits all OM642 engines except on the W166/X166 Mercedes ML & GL, respectively.
There are two seals on the engine. Order two!
