How This Clamp Works

This exhaust manifold to cylinder head repair clamp creates a seal at the manifold-to-head joint when an exhaust manifold bolt has broken off. Instead of extracting the broken stud and removing the cylinder head, the clamp bridges the damaged area and restores clamping force at the leak point. It is a focused repair solution for vehicles such as Chevrolet Silverado 1500, GMC Sierra 2500 HD, Cadillac Escalade, and Chevrolet Camaro applications listed in the fitment data. The Dorman 917-142 is built for front left and rear right positions where the exhaust manifold connection is serviced on the affected side.

Installation Notes and Tips

Inspect the manifold flange, cylinder head surface, and surrounding fasteners before installation. Clean the sealing area thoroughly so the clamp can seat evenly, and verify that the repair location matches the front left or rear right application listed for your vehicle. For GM truck and SUV platforms, confirm engine-side access before starting the repair, especially on Chevrolet Silverado 1500, GMC Sierra 2500 HD, and Cadillac Escalade applications.
