Detailed Description

ATP Parts 101089 is engineered as a direct replacement exhaust manifold for the left side on compatible Chevrolet Blazer, Chevrolet S10, GMC Jimmy, GMC Sonoma, Oldsmobile Bravada, and Isuzu Hombre applications. The manifold is intended to route burnt exhaust gases from the engine into the exhaust system, helping restore proper exhaust flow and sealing where the original part has failed. This part cross-references 674212 and M327188 for the same application.

Over time, exhaust manifolds can crack or warp from heat cycling and age. When that happens, exhaust leaks can create noise, reduce sealing performance, and allow hot gases to escape into the engine bay. ATP 101089 is a practical replacement for drivers searching for a left exhaust manifold for 1998-2001 Chevrolet Blazer 4.3L, 1998-2001 GMC Sonoma left side, or 1997-2000 Isuzu Hombre exhaust manifold applications.

Common Problems This Part Can Address

• Exhaust leak at the manifold or flange area
• Ticking or puffing noise from a cracked manifold
• Warped manifold sealing surface
• Hot exhaust gas entering the engine compartment
• Loss of exhaust system sealing on the left side

Installation Notes and Tips

Verify engine configuration, side, and emissions equipment before installation. This part is listed for left-side applications and notes w/o A.I.R. on several fitments.
