How does coolant get into an engine?
The coolant in an engine is passed through tubes inside the radiator, where heat it has absorbed from the engine is dissipated into the atmosphere , before the coolant returns to the engine. Coolant enters the pipes in an overheated state, causing it to become highly pressurised (aided by turbulence inside the radiator pipes).

What to do if you can't see a leak in coolant?
If you cannot see a leak but you are losing coolant, you may need to perform a coolant pressure test. A pressure tester is a hand-held tool that allows you to gauge the pressure inside your cooling system. If you have low pressure, you probably have a leak somewhere.
How to find a coolant leak?
To locate a coolant leak, first look for puddles of coolant beneath your vehicle. If you see any, you probably have fluid dripping from somewhere in the system. With the car’s engine running, look under the hood to see if you notice any fluid flowing out. If you do, trace the fluid to its source.
