MAHLE Victor Reinz (MAHLE Original gasket line) B33757. OE-quality sealing component/set for diesel engine service.
Are you replacing a worn oil cooler gasket? The MAHLE Oil Cooler Gasket Set is a direct-fit OE replacement designed to seal the engine oil cooler assembly and prevent oil from leaking between the cooler and engine components. A failing oil cooler gasket can lead to oil loss, contamination, and reduced engine reliability. Replacing the gasket set during maintenance or oil cooler service helps restore proper sealing, maintain oil pressure, and ensure the lubrication system continues operating efficiently under demanding driving conditions. Manufactured to meet or exceed original equipment specifications, the MAHLE gasket set is produced using durable sealing materials engineered to withstand engine heat, pressure, and continuous exposure to engine oil. The precision-formed gaskets are designed to maintain a consistent seal between the oil cooler and mounting surfaces while resisting shrink
Notes: Follow MAHLE torque/installation specs. Replace one-time-use fasteners as required. Preserve factory emissions equipment; this listing is not an EGR delete or block-off kit.
