FM reroute thermostat with gasket

These thermostats are specific to the NA-NB FM coolant reroutes. These do not fit in the original thermostat location, they're only for our reroutes. Choose between a standard 195° thermostat to replace a failed unit (stock Mazda temp) or you can select an alternative 180° thermostat (gives you a head start on cooling for especially problematic cars, can postpone warmup).
