Pioneer Cables 612551 Engine Mount - Front or Front Right

Engine Mount for Cadillac, Buick, Oldsmobile and Pontiac

Pioneer Cables 612551 is an engine mount replacement for select Cadillac, Buick, Oldsmobile, and Pontiac applications. It is built for direct-fit service on vehicles that use front or front right hydraulic mounting positions, including several 1985-1993 GM full-size models.

Key Features

• Hydraulic engine mount construction for vibration isolation
• High-grade metal housing with corrosion-resistant coating or pure aluminum housing, depending on application
• Bonded rubber compound matched to the specific vehicle application
• Sure-Fit System application testing for vehicle-specific fitment
• Direct replacement for select front and front right mount locations

Detailed Description

Pioneer Cables 612551 is engineered as a replacement engine mount for select Cadillac DeVille, Cadillac Fleetwood, Cadillac 60 Special, Buick LeSabre, Oldsmobile Delta 88, Oldsmobile 98, and Pontiac Bonneville models. The hydraulic design helps absorb engine vibration and reduce movement at the mount point, supporting smoother operation in the front or front right position where specified. This part cross-references Anchor 2552 for the same application.

The mount housing is manufactured from durable metal or cast aluminum, then paired with a blended rubber compound tailored to the application. Pioneer’s Sure-Fit System uses vehicle-specific testing to help ensure the mount matches the intended installation point. Part number 612551 is a practical choice when replacing a worn hydraulic engine mount on GM rear-wheel-drive platforms from the mid-1980s through early 1990s.

Verify the vehicle’s year, make, model, and design revision against the existing mount before installation. For best results, inspect adjacent engine support components for wear while replacing the mount.
