Coolant leaks can be annoying because they do not always leave a puddle. You top off the reservoir, everything looks fine for a week, and then the level is low again. A cooling system pressure test is one of the quickest ways to catch leaks that only show up under pressure, and it often finds problems before the engine ever overheats. It is a straightforward test, but it is effective because it recreates the conditions your cooling system sees when the engine is hot. Instead of guessing, it lets you see exactly where coolant is escaping.

The system is pumped to a specific pressure, usually close to the rating of the radiator cap. Once it is pressurized, the technician watches to see whether the pressure holds steady or drops.
