Additions:
Coolant was leaking from the drain. bypassed the heater core with the heater hoses to confirm. Replacement of the part requires several hours labor, so not a good time to scrimp on parts, don't want to do it again, so selected OEM part. I ordered the heater core from Rock Auto. I came in 2 days and fit just like the original.
What came in the box? Were additional nuts, bolts, sealant, etc. needed for the repair?
