2011-2016 Duramax Engine Oil Cooler Assembly (12732979)

Even though the engine oil cooler usually holds up, it's wise to swap it out after any major engine catastrophic failure. Any time that metal is pumped through the engine from internal failure that crud can pile up in the cooler. Due to the stack plate design of the oil cooler, cleaning out that debris can be nearly impossible. Save yourself the trouble and protect a new engine by getting a fresh cooler.

• Even though the engine oil cooler usually holds up, it's wise to swap it out after any major engine catastrophic failure. It can also be the source of coolant/oil cross contamination. If you have a layer of oil in your coolant bottle, carefully check the engine oil cooler for issues.
• An easy way to test the oil cooler is to remove the oil filter and pressure test the cooling system. Any air escaping from the area on the oil cooler where the oil filter screws on is an indication of it leaking internally. This should be replaced.
