Keeping coolant temperatures down is vital for turbocharged motors. GrimmSpeed's 160 degree thermostat keeps coolant temperatures consistant and in most cases 20-30 degrees cooler than the factory unit. On the off chance that this thermostat would fail, it will never fail closed causing your motor to overheat. This is ideal for Genesis Coupes that see a lot of track time as coolant temperatures can peak and cause damage to your motor.
