Grade 9 Carbon Steel Intake Manifold Bolt, 98.5 mm, M8 x 1.25 Thread for 1994-2011 GM Vehicles
Dorman 03426 is a direct-replacement intake manifold bolt for many GM V6 engines used in Buick, Chevrolet, Oldsmobile, Pontiac, and Saturn vehicles. It replaces missing, fatigued, or damaged original manifold hardware so the intake can be secured correctly during gasket service or engine repair. Its Grade 9 carbon steel construction, hex head, and OE-style M8 x 1.25 thread help match the factory fastening point without guesswork.
Dorman 03426 Installation Notes:
- M8 x 1.25 medium thread and 98.5 mm length are specified for OE-style intake manifold fastening on covered GM V6 applications.
- Grade 9 carbon steel construction provides the strength needed for the clamping loads and heat cycles found around the intake manifold.
- Standard hex head drive supports straightforward removal and installation with common shop tools.
- Red and silver finish helps resist corrosion and makes the replacement hardware easier to identify during future service.
- Designed to match the fit, form, and function of the original intake manifold bolt for a dependable repair when factory hardware is missing or failed.
Apply RTV sealant to the threads during installation because this bolt location can pass into an engine coolant passage. Proper thread sealing helps prevent coolant leaks after intake manifold service.
