Dorman 674-340 Exhaust Manifold for Transit Vans
Dorman 674-340 is a standard replacement exhaust manifold engineered to match the fit and function of the original part on specified Ford Transit vans. Built from cast stainless steel with a metallic gray finish, it includes the outlet gasket needed for a complete exhaust manifold repair.
Key Features
- Cast stainless steel construction for exhaust durability
- Round port shape with a 1.1 collector port diameter
- Standard replacement grade for OE-style fit and function
- Includes gasket or seal for the outlet connection
- 12 mounting holes for the specified application
- No oxygen sensor port and no heat shield included
Detailed Description
This exhaust manifold is built for the left side of 2015-2025 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD models. It is engineered to replace the original manifold on these Ford Transit applications with the correct mounting layout and exhaust port configuration. Part number 674-340 is also referenced by interchange number BL3Z9431D for the same application.
For buyers searching for a Ford Transit-150 left exhaust manifold, Ford Transit-250 left exhaust manifold, or Ford Transit-350 HD left exhaust manifold, this Dorman replacement provides the core fitment and hardware interface needed for a direct repair. The cast stainless steel body and round-port design support a factory-style exhaust connection on the specified vehicles.
Common Repair Uses
- Cracked or leaking exhaust manifold on the left side
- Exhaust noise from a failed manifold-to-head seal
- Exhaust odor entering the cabin from manifold leakage
- Broken or warped manifold flange at the outlet connection
- Loss of exhaust sealing on high-mileage Ford Transit vans
Installation Notes
Verify left-side fitment before ordering and match the vehicle year, model, and exhaust layout to the listed applications. Inspect the cylinder head sealing surface, fasteners, and downpipe connection during installation so the new manifold can seal correctly. Because this manifold does not include an oxygen sensor port, confirm your original exhaust configuration matches this design before replacement.
Quality Assurance
Dorman manufactures this manifold as a standard replacement part to match original fit and function on the specified Ford Transit applications. Part number 674-340 is built for direct replacement use on 2015-2025 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD left-side applications.
