Disconnect heater core inlet and outlet hoses - couple them together
You don't repair, you replace.
replace it. there is no repair
To replace your heater core on a 1993 caprice, you will need a screwdriver, a socket wrench, and a weather seal adhesive.
The dash must be completely removed in order to gain access to the heater box. Then the heater hoses are disconnected and the heater box is removed and opened up. That gains access to the heater core for relacement.

The PCU is inside the console up towards the front directly below the heater/AC controls.
It's tough for an amateur. The heater core is inside behind the console.
It'll cost around $1000
