Engine cooling is crucial to your engine's reliability and long life. Running your engine too hot, or starving it of coolant will certainly lead to engine failure. Having a reliable, properly functioning thermostat, and a thermostat housing that doesn?t impede coolant flow, or leak fluid, is the surest way to keep your vehicle's powerplant in good working order.

Trans-Dapt waternecks are available for most popular classic American Chevy, Ford, MOPAR, Oldsmobile and Pontiac cars and trucks. Many models are available in a variety of materials and finishes. Choose between steel (Chrome, Black, Chevy Orange or Ford Blue), or aluminum (polished or black) construction.

All Trans-Dapt water necks include mounting hardware and either a gasket or o-ring, depending upon the housing style.
