The Story
05-10 Chevrolet Cobalt/HHR Aluminum Exhaust Header Gasket
Aluminum construction seals your header-to-manifold joint without warping or blowout. Engineered to handle repeated heat cycles on stock and modified engines. Direct fit for your platform's factory mounting points.
Key Features
- Aluminum core material - Resists thermal warping better than composite gaskets under sustained exhaust heat
- Factory bolt pattern - Seats at OEM mounting points with no drilling or modification required
- Single-piece design - Eliminates multi-layer failure points that cause exhaust leaks
Specs
- Material: Aluminum
- Configuration: Single gasket
- Condition: New
What's Included
- Exhaust header gasket (1)
Frequently Asked Questions
Do I need to clean the header and manifold surfaces before install?
Yes. Scrape off old gasket material and carbon buildup with a gasket scraper or wire brush. Wipe both surfaces clean with a rag to ensure a proper seal.
Will this gasket work with a stock manifold or only headers?
This gasket is designed for the header-to-manifold interface on your engine. Confirm your setup matches the factory bolt pattern before ordering.
What torque spec should I use when bolting it down?
Refer to your vehicle's service manual for the correct fastener torque sequence. Over-tightening can crush the aluminum and cause leaks; under-tightening will result in exhaust seepage.
