Step 1: Disconnect heater hoses from under the hood Step 2: Remove the (6) 9/32" screws securing the heater box cover to the bottom of the heater box. Note: (2) of them are hidden so make sure you get them all. Step 3: Remove the heater box cover. Step 4: Locate the (1) 9/32" screw that holds the heater core to the housing. Step 5: Gently pull the heater core from the housing and remove. Installation is the reverse of disassembly.

Drain the water from your 1990 Chevy Corsica cooling system. Remove the heater core water supply hoses. Remove the heater core retaining bolts. Reverse the process to install the new heater core.

If your 1990 Chevy silverado is a short bed (6 foot), 350 cu. in. V8, and you're using the rear bumper to tow from, then the capacity is 4000 pounds. The tongue weight is 400 pounds.
