Signs the radiator vent valve is faulty

• Coolant spills out when the engine is running.

• The temperature light comes on or the engine temperature rises abnormally.

• Air bubbles in the radiator, or the level in the expansion tank fluctuates sharply.

• Loss of cooling system pressure, causing the engine to heat up quickly.
