A customer says the coolant reservoir needs topping off about every week, but no puddles or wet spots are ever found under the vehicle. With the engine cold, the technician removes the cap, installs a cooling system pressure tester on the filler neck, and pumps the system up to the cap's rated pressure. The gauge holds steady for 15 minutes with no visible leaks anywhere.
Technician A says this proves there is no internal leak, so the technician should simply top off the coolant and tell the customer to monitor the level.
Technician B says a steady reading on a cold, static pressure test does not rule out an internal leak (such as a head gasket) that only shows up when the engine is hot and under load, and recommends further tests such as a combustion leak (block) test or cylinder leakage test before releasing the vehicle.
