Product Description
Michigan Motorsports 180 Degree Thermostat for LS Engines
High-Flow Replacement Thermostat | Replaces LS1 / LS2 OEM Thermostat
The Michigan Motorsports 180 Degree Thermostat is a high-quality replacement designed for LS1, LS2, and pre-2008 LS-based engines that use a separate thermostat and water neck. This thermostat opens consistently at 180°F, regardless of engine RPM, helping maintain stable operating temperatures and improved cooling performance.
Featuring a high-flow design with durable brass and copper construction, this thermostat reduces the harmful effects of temperature cycling commonly experienced in stop-and-go traffic. It’s an excellent upgrade for both stock and performance LS applications looking for more consistent coolant control.
