Thermostat Housing GM LS w/16AN - Clear

The CVR Performance Thermostat Housing GM LS w/16AN in clear anodize is designed for LS engine builders and performance mechanics who require precise cooling management in high-output applications. This aftermarket housing replaces the factory thermostat location with a durable billet-aluminum design that features 16AN inlet and outlet ports for flexible coolant line routing.

CNC-machined from 6061-T6 aluminum and finished in clear anodize, the TSH5ACL housing maintains structural integrity under pressure while providing visibility of internal coolant flow. The 16AN port standard accommodates industry-standard braided stainless steel or silicone hose with corresponding fittings, ensuring leak-free connections and the ability to run larger-diameter coolant lines that enhance heat transfer efficiency.

This thermostat housing is particularly beneficial for LS swappers, drag racers, and street performance enthusiasts when paired with a high-flow radiator and a quality thermostat valve rated for their target operating temperature. Its compact footprint fits within typical LS engine bay constraints, making installation straightforward for experienced builders.
