Replaced 3 radiator hoses and followed your process to refill, but now have leak from driver's side of engine. Removed battery box for visibility, attached a pressure tester & pumped up to rated psi. Can't see anything leaking, or even dripping under car, but pressure gauge bleeds down in ~ 10 seconds. Any ideas?

Grab a mirror and inspect the area. There may be a seal or gasket leaking. Check if the cooling blocking plate or elbow for coolant pump on the crankcase are leaking.
