Keep your classic Chevy's cooling system running the way it should with the Motorad CH4820 engine coolant water outlet. Built from steel and finished in silver, this standard-type outlet is designed for a 1.61 in (40.89 mm) outside diameter and features two mounting holes for a secure fit. A gasket is included, so you can install it without hunting down a separate seal, though mounting hardware is sold separately. Motorad has been supplying cooling system components since long before many of these classic Chevrolet models rolled off the line, and the CH4820 covers a wide range of Bel Air, Impala, Corvette, El Camino, and pickup applications from 1955 through 1967. Whether you're maintaining a daily driver classic or restoring a project car, this outlet gives you a straightforward, factory-style replacement for your cooling system.
Features
- Steel construction offers durable, corrosion-resistant service for a factory-style repair.
- Included gasket saves time and a separate parts trip during installation.
- Two mounting holes support a secure, stable fit to your engine.
- 1.61 in outlet diameter matches original coolant outlet sizing for proper hose fit.
- Broad 1955-1967 Chevrolet coverage spans Bel Air, Impala, Corvette, and pickup models.
