Seal the Leak: Thermostat Housings & Water Outlets
Is your classic car leaking coolant right at the top of the engine? The Thermostat Housing (also known as a Water Outlet or Water Neck) is one of the most prone-to-failure cooling parts. Over decades, electrolysis and corrosion eat away at the metal, causing deep pits on the gasket surface that no amount of sealant can fix.
At Old Car Parts NW, we stock authentic NORS (New Old Replacement Stock) and high-quality replacement housings to restore a leak-free seal.
Why Replace Your Old Housing?
Eliminate Pitting: Once the mating surface is corroded, the gasket cannot seal properly. A fresh casting is the only permanent fix.
Avoid "Cheap Chrome": Many budget aftermarket chrome housings are made of thin metal that warps instantly when tightened. Our inventory focuses on robust cast iron and heavy-aluminum units designed to OEM specifications.
Correct Hose Angles: Don't struggle with kinked radiator hoses. We carry housings with the specific 45°, 90°, or straight angles required for your Ford, Chevy, Mopar, or AMC engine.
Inventory Highlights:
Cast Iron Housings: Essential for factory-correct restorations.
Aluminum Water Necks: High-quality replacements for intake manifolds.
Gaskets & Hardware: Don't forget the matching thermostat gasket for a perfect seal.
