| | This genuine TRD High Performance thermostat from TRD Japan will really help your cooling system reach its peak potential! Your stock Toyota thermostat opens at 180°F, which is good for everyday driving. TRD Japan's High Performance thermostat opens at 160°F, though, for quicker cooling when your engine is working hard. Running without a thermostat can be hazardous to your cooling system. Install one of these quality TRD Japan thermostats when you need the right balance of cooling effectiveness. A new Toyota gasket is also included. |
