Toyota Thermostats

The thermostat of an engine acts as the auto-regulating valve between the inflow of coolant to the radiator. It is very important that the radiator be allowed to reach a certain temperature before the inflow of coolant. This is because without the radiator reaching a certain critical heat level, the car will not warm up properly and the ignition will not catch. This is often observed in cool weather where a care becomes difficult to start. The thermostat controls the amount of coolant going to the radiator and makes it run efficiently, so it's definitely not a part to take lightly.
