Hi lreddy,
Thank you for the donation.
If you are losing coolant both at recovery tank and radiator, there is a leakage somewhere and if it is a mini leak, pressure testing might not be conclusive.
Reason is that the leak might happen only when hot ot when cold. Usual areas for leaks would be hose joints, water pump, radiator cap and radiator drain plug.
When the radiator drain plug leaks, it is always difficult to diagnose and often missed out.
One way of sourcing for leaks is to note the presence of coolant.
