Don't over pressurize. One of WAZOO car had a blown heater core which MAY have been the result of over pressurizing at the dealer service looking for coolant leak.
Heater core is not fun to replace.

Another possible leak area is radiator plastic tank (assuming you still have OEM radiator). These typically crack about 1/3 way down from the top.
