The Dorman 902-846 Engine Coolant Water Outlet is a direct-fit replacement part engineered to restore proper coolant flow and sealing on compatible Chevrolet and Buick 4-cylinder engines.

If your vehicle's water outlet shows signs of leakage, cracking, or corrosion, replacing it with a correctly fitted aftermarket unit prevents overheating and preserves cooling-system performance. Dorman designs this outlet to match original dimensions and mounting points while using materials chosen to resist thermal stress and corrosion for longer service life.

How does this water outlet match the original equipment?

• Engineered to the same mounting geometry as the stock outlet
• Compatible hose fittings and thermostat housing interface
• Prepares for standard gaskets or O-rings used on the original assembly

Will it withstand the heat and pressure inside the cooling system?

The 902-846 uses materials and construction aimed at resisting repeated temperature cycles and coolant exposure that can cause cracking or warping. While no part is immune to extreme abuse, this outlet is built to tolerate normal operating temperatures and pressures typical of small-displacement gasoline engines.
