Dorman 674-869 Exhaust Manifold
Dorman Exhaust Manifold 674-869
This Dorman exhaust manifold is an OE FIX replacement for select 2008-2009 Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, and 2008 Isuzu Ascender applications. Built from high-grade ductile iron, it addresses the cracking and warping issues commonly associated with lower-grade original manifolds.
Key Features
- Cast iron exhaust manifold construction with a natural finish
- High-grade ductile iron design for improved heat and stress resistance
- Irregular port shape for the listed vehicle applications
- Gasket or seal included for installation support
- Heat shield included
- Mounting hardware included
- Direct replacement part number 674-869 for select GM and Saab platforms
Detailed Description
Dorman 674-869 is engineered as a replacement exhaust manifold for vehicles that commonly experience manifold cracking or distortion from thermal cycling. The ductile iron construction is selected to better tolerate exhaust heat and engine stress than lower-grade OE castings, helping maintain a secure seal at the cylinder head and exhaust flange. This part is a practical choice for 2008-2009 Chevrolet Trailblazer and GMC Envoy owners, as well as Saab 9-7x and 2008 Isuzu Ascender applications that need a durable exhaust manifold replacement. This part cross-references ATP 101466 for the same application.
Common Problems This Part Can Address
- Exhaust leaks caused by a cracked manifold
- Warping at the manifold sealing surface
- Ticking or puffing noises from the exhaust side of the engine
- Failed manifold gasket sealing at the head or flange
- Heat-related deterioration of the original exhaust manifold
Installation Notes and Tips
Verify engine and vehicle fitment before installation, especially on 2008-2009 Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, and 2008 Isuzu Ascender applications. Inspect the cylinder head surface, flange surface, and fasteners for damage or corrosion before assembly. Use the included gasket and hardware as specified by the service procedure, and confirm proper alignment of the heat shield during installation. The part number 674-869 should be matched to the vehicle’s exhaust configuration before final fitment.
Quality Assurance
Dorman positions this OE FIX manifold as an upgraded replacement for original manifolds that are prone to heat-related failure. The cast iron construction, included gasket set, heat shield, and mounting hardware support a complete repair for the listed applications.
