Detailed Description

The Standard Ignition PVS108 is designed for vehicles that use a ported vacuum switch to manage vacuum signals within the emissions system. Its brass and heat-resistant plastic housing supports durability in underhood conditions, while the thermal design helps maintain consistent switching behavior. This part is a direct-fit style replacement for a range of late-1970s and early-1980s GM vehicles, including Cadillac, Chevrolet Camaro, Buick Regal, Oldsmobile Cutlass, and Pontiac Grand Prix applications. This part cross-references 2-29156 and 7P1035 for the same application.

What It Is Used For

Restoring proper vacuum signal control in emissions systems
Replacing a cracked, leaking, or heat-damaged vacuum switch

Supporting accurate vacuum switching on compatible Cadillac, Chevrolet, Buick, Oldsmobile, and Pontiac models

Installation Notes and Tips

Verify the thread size, hose connector count, and vehicle application before installation. Confirm the original switch color and port layout match the existing part, especially on 1979-1984 GM vehicles. Use the vehicle service information to route vacuum hoses correctly and ensure the replacement is installed in the proper emissions-system location.
