Description
Replace your leaking or worn thermostat housing gasket with this Genuine OEM GM 97223686 Coolant Thermostat Housing Gasket, designed for 2001–2016 Silverado and Sierra 2500HD/3500HD Duramax diesel engines.
This gasket seals the front coolant crossover (thermostat housing) to the cylinder head, preventing coolant leaks and ensuring proper cooling system performance. Each Duramax engine uses two gaskets — one per cylinder head — so be sure to order two if you’re servicing both sides.
Features & Benefits:
- Genuine OEM GM part – not aftermarket
- Ensures proper seal between thermostat housing and cylinder head
- Prevents coolant leaks and overheating
- High-quality material for long-lasting durability
- Easy to install, direct-fit replacement
Fitment: 2001-2016 Chevy/GMC Duramax Diesel 6.6L LB7 / LLY / LBZ / LMM / LML
