Thermostat 180F

The Toyota 90916-03075 is a genuine OEM thermostat, engineered as a direct replacement for various Toyota models. It is designed to open at 180 degrees Fahrenheit and includes a jiggle valve for proper installation and operation. This thermostat is compatible with a wide range of Toyota vehicles, including the 4Runner (1996-2002), Camry (1988-1994), Celica (1990-1993), MR2 (1990-1995), T100 (1994-1998), Tacoma (1995-2004), and Tundra (2000-2005). Specific trim levels and engine options are detailed in the vehicle fitment list. When replacing a thermostat, it is recommended to first check the coolant level, drive belt tension, and temperature gauge. The replacement process involves detaching the battery's negative cable, draining the cooling system, and carefully removing the thermostat housing. After installing the new thermostat and housing, tighten the fasteners and refill the cooling system. It is important to note that driving a fuel-injected vehicle without a thermostat can cause the computer to remain in open loop, negatively impacting emissions and fuel economy. This part does not include a gasket or O-ring, which must be purchased separately.
