Pressure testing is the best

Pressure testing is the best way to find an illusive cooling system leak.

Have the system pressure tested
at a garage. This is not a major process, as a matter of fact the pressure test is hand held and operated. This tool allows the tech to put pressure on the cooling system, which forces water through any crack you may have, thus, revealing the leak (repair accordingly).

Make sure that the cooling system is full before pressure testing.
