Detailed Description

Fel-Pro 35656 is an engine water pump gasket for lower water pump-to-block sealing points. The premium construction, black finish, and 0.218 thickness are selected to support a precise seal where coolant passages and mounting surfaces must align correctly. This gasket is a direct fit for a wide range of GM vehicles, including Buick Lucerne, Cadillac DTS, Cadillac DeVille, Pontiac Bonneville, Oldsmobile Aurora, Cadillac Seville, Cadillac Eldorado, and Cadillac Allante applications.

This part cross-references OE-style numbers such as 123301 and 1647295 for the same application. If you are replacing a leaking water pump gasket on a 2006-2011 Buick Lucerne or a 1994-2005 Cadillac DeVille, Fel-Pro 35656 provides the correct lower, to-block sealing profile.

What It Helps Fix

• Coolant seepage at the water pump-to-block joint
• External coolant leaks around the lower water pump area
• Sealing issues caused by worn or compressed gasket material
• Improper sealing after water pump service
• Fitment problems when replacing an OE-style lower gasket

Installation Notes

Clean both mating surfaces thoroughly before installation and verify the lower, to-block orientation matches the original part. Check the water pump and block surfaces for corrosion, pitting, or residue that could affect sealing. Confirm the gasket aligns with the 2 mounting holes and the application-specific shape before final assembly.

Quality Assurance

Fel-Pro gaskets are built around vehicle-specific sealing materials and application-focused design to support reliable sealing performance in professional repair work.
