What is a jiggle valve on a thermostat?
These thermostats are equipped with a jiggle pin valve in the flange. This valve prevents air lock from occurring in the cooling system by allowing trapped air to escape while also reducing coolant leakage through the flange. Air lock and leakage hinder the operation of a thermostat during engine warm up.
Why is my Toyota overheating?
Some causes of this would be a thermostat that won’t open when it should, mineral deposit blocking the radiator or a foreign object inside the radiator. A failed water pump is a common occurrence for a Toyota overheating, usually due to a bearing or impeller inside the pump wearing out.
