Description
Description
This is a genuine OEM GM Duramax Diesel L5P Max-Flow Engine Oil Cooler Assembly that comes on the 2020+ L5P trucks which had a siugnificant towing capacity increase.
The Duramax engine oil cooler is not normally a component that goes bad, however, it should be replaced after any catastrophic engine failure or during any performance engine builds and is a great upgrade for 01-19 trucks!
The factory oil cooler has a stack plate design which makes cleaning any debris out nearly impossible. This is the reason we always recommend replacing the oil cooler. A defective engine oil cooler is also a major source for coolant/oil cross contamination. Check your coolant degas bottle for a layer of oil. If any appears, it is often defective oil cooler.
Replaces OEM Part Numbers: 12717102, 12728248, 12734217, 12735508
This coolers massive 31%+ increase in cooling capacity makes it a great upgrade for 2001-2019 trucks.
