Product Description

Improve cooling efficiency and help manage engine temperatures on your C7 Corvette with the Mishimoto Racing Thermostat. Designed specifically for the 2014–2019 Chevrolet Corvette LT1/LT4, this performance thermostat lowers the coolant activation temperature compared to the factory unit, allowing coolant circulation to begin earlier and helping modified engines maintain more consistent operating temperatures during demanding driving conditions.

Mishimoto thermostats are a popular upgrade for C7 owners running increased power, forced induction, aggressive tuning, track setups, or vehicles that regularly see high-load conditions. By reducing thermal stress and improving coolant flow earlier in the heat cycle, this thermostat helps support improved reliability and temperature control.

Why Upgrade?

The factory C7 Corvette thermostat is designed around emissions, fuel economy, and everyday drivability—not maximum performance under repeated high-load conditions. As horsepower increases or track use becomes more frequent, maintaining stable temperatures becomes increasingly important.

The Mishimoto Racing Thermostat is a simple but effective cooling upgrade that complements other performance modifications such as superchargers, headers, exhaust systems, intake upgrades, and ECU tuning. By allowing coolant flow earlier, it helps provide additional thermal headroom for enthusiasts pushing their LT-powered Corvette harder.
