About This Product

Doing maintenance on a Detroit Diesel engine? You'll likely need these oil cooler gaskets! This is a custom bundle that includes both the INNER and OUTER oil cooler gaskets. The part numbers covered are 23501591, 5150155, and 8923223. These are genuine quality parts from brands like GM and Federal Mogul. They're brand new, made in the USA, and come in their original packaging. These gaskets are crucial for sealing the oil cooler to the engine block, preventing oil and coolant from mixing—a serious problem you want to avoid. Replacing these during a rebuild or coolant system service is cheap insurance.

A small part for a big engine!
