Granatelli14-20 GM LT Billet Thermostat Housing w/180 Deg Thermostat

If you're looking to get a better handle on your GM LT engine's operating temperature, especially after modifications or for track use, this billet thermostat housing from Granatelli Motor Sports is a solid option. It replaces the factory plastic housing with a much stronger, well-built aluminum piece, and it comes pre-installed with a 180-degree thermostat, which helps keep your engine running cooler than the stock unit.

This housing is machined from solid billet aluminum, making it significantly more durable than the original plastic part, which can become brittle over time or warp under high heat. The included 180-degree thermostat is designed to open sooner, allowing coolant to circulate through the radiator at a lower temperature. This can be beneficial for engines that run hotter than stock, helping to prevent overheating and maintain consistent performance. It's a direct replacement for many popular GM LT-powered vehicles, including models like the Chevrolet Corvette, Camaro, and Cadillac Escalade.

When installing this, you'll want to make sure you have fresh coolant on hand. It's a good idea to check the condition of your radiator hoses at the same time, as they can also degrade over time. This housing is a straightforward upgrade that offers improved durability and better temperature management for your LT engine.
