Thermostat Housing GM LS w/ 1-1/2 - Clear

The Thermostat Housing GM LS w/ 1-1/2 - Clear from CVR Performance is a precision cooling system component designed for LS engine builders and street performance enthusiasts. This billet aluminum housing replaces the factory plastic unit, which can fail under high-heat conditions or aggressive tuning scenarios. It is suitable for stock LS engines, modified street engines, or dedicated track builds, providing improved reliability and visibility into coolant flow dynamics.

Constructed from high-quality billet aluminum, this thermostat housing features a clear sight window that allows real-time monitoring of coolant condition and flow without disassembly. The clear window helps diagnose cooling issues by allowing immediate visibility of air pockets, contamination, or insufficient circulation. The compact footprint (5.5 x 2.65 x 8.45 inches) maintains clean engine bay aesthetics while integrating seamlessly into most LS swap configurations.

This housing is ideal for LS engine swaps, supercharged or turbocharged builds, and any application where thermal management and system diagnostics are crucial. Installation is straightforward for anyone familiar with basic coolant system work, and the 1-1/2-inch port accommodates standard fittings, making it a versatile choice for performance enthusiasts.
