Fel-Pro Chevrolet Colorado ES 73486 Engine Cylinder Head Bolt Set

If you're rebuilding the top end of your Chevrolet Colorado, or another compatible GM vehicle, you'll need a fresh set of cylinder head bolts. This set from Fel-Pro, part number ES73486, is designed to meet or exceed original equipment specifications, ensuring a reliable seal when you reassemble your engine. It's important to replace Torque-To-Yield (TTY) head bolts rather than reusing them, as they can stretch during the initial torquing process and may not hold proper clamping force if reused, leading to potential leaks or other engine issues.

Fel-Pro builds these bolt sets with the repair environment in mind, meaning they're made to work even if your sealing surfaces aren't perfectly flat. This application-specific design means they fit right and function as intended, giving you confidence during installation and after the engine is running. You can count on Fel-Pro for sealing solutions that handle real-world repair challenges.

This set is designed for a range of GM vehicles, including popular models like the Chevrolet Camaro, GMC Canyon, and Cadillac ATS, among others. Always refer to the manufacturer's installation instructions for proper torque specifications and sequence when installing these head bolts.
