Description
Routing the upper radiator hose from a Chevrolet V8 intake requires the correct thermostat-outlet angle. Proform 66209 offers a polished chrome-aluminum 45-degree water neck for compatible small-block and big-block engines.
The O-ring style flange and included fastening hardware make this a separate thermostat-housing accessory, not a complete cooling-system kit. Confirm the mounting pattern and thermostat arrangement on the engine before fitting.
