The easiest way to check for cooling system leaks is with a pressure test. Regulated pressure is applied to the cooling system and any leaks would appear.
A visual inspection can be carried out whereby you look for signs of coolant spilled onto engine components. If no coolant leaks are visible, the most likely place would be the gheater core. Look under the carpets to see if they are damp or soaked.
