Coolant Leak Location?

2002 Disco2. Coolant leaks back of the engine so that it drips on the passenger side catalytic converter. I can't seem to be able to trace where it is leaking from. Only leaks when it gets up to running temperature. In fact, it didn't leak until I switched on the AC. Any idea?

I hate to say it, but that sounds a great deal like an external head gasket leak. Mine P38 (same engine) had the very same symptoms.

Get the coolant dye and it will be pretty obvious.

Is it coming from the valley? Are you sure it isn't the heater hoses?

How can I tell if it's coming from the heater hoses?

get the dye for the coolant and it will be pretty obvious. You have fluorescent trails wherever coolant escaped.

Pressure testing the cooling system should show you where the leak is.
