What causes air locks in cooling system?
The most common cause of radiator air lock is a failure to maintain pressure. 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. Air can also enter the system, causing air pockets to be caught inside.
What causes vacuum in cooling system?
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. As the engine cools, if fluid cannot return to the tank, this will also cause a vacuum. Additionally, it is possible that your radiator is clogged or dirty, but if that’s the case, you’re likely to have some overheating.
What happens if there’s air in your coolant system?
When you have air in your coolant system, it causes steam pockets in the line which act almost like plugs preventing the coolant from continuing to flow. That’s why you end up with your engine overheating, because the coolant isn’t allowed to continue through or it moves very slowly.

Why do I have air pockets in my cooling system?
Air trapped in the lines of your cooling system can make a perfectly healthy system run as though it’s malfunctioning. These air pockets accumulate over time and can cause overheating by impeding the flow of coolant through the system. They also make the coolant level appear to be high when in fact it is just air pushing the coolant level up.
Where is the air lock in a heater?
Here is a brief description on the two most common air locks experienced and how to try rid your cooling system of air.

However, allowing air to get trapped in the cooling system can have negative effects on the overall performance of your cooling system. On occasion Evans Cooling Systems have received feedback from customers, that after installing Evans, they have noticed a coolant temperature increase of well over 15C…….this is not normal!
