FAQ

Will this fit my 5.9L 24-valve (1998.5+)?
This listing targets 1989–1997 12-valve applications. 24-valve ISB engines may use a different gasket. Verify by ESN and housing casting numbers before purchase.
Where does this gasket go?
It seals the joint from the oil cooler to the oil filter head on the right-hand side of the engine block (B-Series layout).
What else should I replace while I’m here?
Inspect the cooler core, O-rings, and the block-side cooler gasket (often referenced as 4932124 on many catalogs). Replace any hardened or damaged seals to prevent future leaks.
Do I need sealant on this joint?
Generally no—install the dry gasket on clean, flat surfaces. Use sealant only if the service manual calls for it for your ESN.
What torque spec should I use?
Follow the Cummins service manual for your exact model/ESN. Torque varies by housing and fastener size.
