Specs At A Glance

Good To Know

Q: Does this housing come with a thermostat or gasket? A: This listing covers the swivel thermostat housing itself, so a thermostat and gasket are typically sourced separately. Check the listing contents before buying if you need those parts.

Q: Can the outlet be rotated after installation? A: The swivel design lets you set the outlet angle to match your radiator hose, then tighten it down. Position the neck before final tightening to avoid leaks.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
