Detailed Description

ATP Parts 101403 is an OE-style exhaust manifold engineered for vehicles that need a direct replacement after manifold damage or leakage. When an exhaust manifold cracks or warps, exhaust gases can escape before reaching the exhaust system, which can create noise, odor, and heat-related concerns under the hood. This manifold is designed to restore the exhaust system’s sealing and routing on applications including the Chevrolet Trailblazer, GMC Envoy, and Buick Rainier. It also cross-references Monroe Shocks & Struts 674777 for the same application.

Common Issues This Part Can Address

• Exhaust leak at the manifold
• Ticking or puffing noise from the engine area
• Warped or cracked original manifold
• Exhaust odor entering the cabin
• Heat escaping into the engine compartment

Installation Notes and Tips

Verify engine and vehicle fitment before installation. Inspect the exhaust flange, gasket surfaces, and fasteners for wear or damage during service. Proper sealing at the manifold is important to prevent repeat leaks and to maintain correct exhaust flow. Fits 2004-2005 Buick Rainier, N/A. Fits 2002-2005 Chevrolet Trailblazer, N/A.
