180° High-Flow Thermostat – GM LS-Series

A high-flow 180-degree thermostat engineered for consistent operation on GM LS engines. Its brass and copper construction resists corrosion and prevents temperature cycling, especially in stop-and-go driving. Designed to open at 180° regardless of RPM, it provides improved cooling control for performance applications. Includes the correct rubber O-ring seal and features an integrated pressure relief valve. Made for use with Mr. Gasket water necks 2670, 2671, or 2672.
