Radiator - Cooling System Test
It is recommended to have a radiator and cooling system test normally once every two years.
Radiator - Cooling System Tests include:
1. Pressure test the radiator cap – ensures that the cap releases coolant back-pressure at the appropriate pressure.
2. Thermostat test – verifies proper flow of the coolant at the required temperature.
3. Fan test – checks if the engine fan including other fans are operating properly and are in good condition.
4. Pressure test on the system – this test inspects if there are any leaks formed when the cooling system is put under pressure.
If your mechanically inclined and would like to do the testing yourself, here’s a list of Radiator Pressure Testers available to help with the job.
