Low Temp. Thermostat 180 Degree LS1 - LS3

The Low Temperature 180 Degree Thermostat for LS1–LS3 engines is a precision cooling system component designed to maintain optimal engine operating temperatures in GM's sixth and seventh-generation small-block architectures. This thermostat is specifically engineered for applications where fine-tuning of thermal management is necessary, particularly in modified engines or those operating in warmer climates.

The 180-degree opening temperature specification indicates that the thermostat begins to open at 180°F, facilitating increased coolant circulation as engine temperatures rise. This lower temperature rating compared to OEM specifications is beneficial for certain performance builds, as it helps prevent overheating and maintains oil viscosity, thereby enhancing component longevity.

This replacement thermostat is compatible with LS1, LS2, LS3, and other LS variants manufactured between 2006 and 2014, making it a versatile choice for street-driven vehicles and engine swaps. Whether addressing cooling issues in modified engines or replacing a failed original unit, this thermostat provides an effective solution for temperature-sensitive tuning.
