Detailed Product Overview

This Dorman exhaust manifold, part number 674-155, is designed for Ford Bronco, Econoline, and F-Series vehicles from the 1983-1987 model years. The cast iron body supports exhaust heat and long-term service, while the OE-style layout helps restore proper exhaust routing on the left side. The part number 674-155 is also a practical match for repair work where the original manifold has cracked, warped, or developed leaks.

Common Repair Uses

• Exhaust manifold leak at the cylinder head
• Cracked or warped manifold casting
• Broken or missing mounting points on the original manifold
• Exhaust noise from a failed manifold gasket seal
• Damaged downpipe connection on the left side

Installation Notes

Verify engine configuration and emissions equipment before installation, especially on vehicles listed with exhaust control valve or A.I.R. notes. Confirm left-side placement and compare the port shape, gasket surface, and hardware layout to the original manifold before assembly. The included gasket and mounting hardware support a more complete repair, but the mating surfaces should be cleaned and inspected carefully for best sealing.

Quality Assurance

Dorman engineers this manifold to match the original fit and function on the listed vehicles. The cast iron construction and OE-style design support a repair that follows the factory configuration for the specified Ford Bronco, Econoline, and F-Series applications.
