Mishimoto Low Temp Thermmostat

2005–2010 Scion tC / 2008–2015 Scion xB / 2008–2014 Scion xD

Part #: MMTS-TC-05L

Overview

The Mishimoto Low Temp Thermostat is a high-performance cooling component engineered specifically for select Scion models, including the 2005–2010 tC, 2008–2015 xB, and 2008–2014 xD. Designed to improve engine cooling efficiency, this thermostat activates at a lower temperature of 68°C (155°F) compared to the OEM thermostat’s 82°C. This earlier activation allows coolant to circulate sooner, helping to reduce and maintain optimal engine temperatures, especially under demanding driving conditions or when the engine has been modified for increased power.

Ideal for enthusiasts who have upgraded their Scion with turbochargers or other performance modifications, the Mishimoto Low Temp Thermostat helps prevent overheating and promotes consistent engine performance. By maintaining cooler operating temperatures, it supports engine longevity and reliability during spirited driving or track use.
