Answers
Answer:
What is radiator airlock? Simply put, it is the presence of air bubbles inside the cooling system. Even a small amount can create air pockets which prevents proper circulation of coolant. Signs and symptoms of radiator airlock include: Overheating during normal driving.
Answer:
An air lock (or vapor lock) is a restriction of, or complete stoppage of liquid flow caused by vapour trapped in a high point of a liquid-filled pipe system.
The most common cause of radiator air lock is a failure to maintain pressure. This can often involve the radiator cap. The cap not only makes sure there is no coolant spillage, but maintains the pressure in the system. If this fails at high temperature, air pockets can form.
The gas, being less dense than the liquid, rises to any high points. Air bubbles in a fuel line can lead to stalling, hiccuping or refusal to start.
