What Are You Doing To/With Your Car Today?

Yesterday put 1/4 cup of dish soap in the radiator and drove it some here and there.
Dropped that out this morning and refilled with 2 gallons of vinegar, warmed up to 190 and let that soak for a couple of hours.
Drained that and water/air backflushed the radiator and block and refilled with new coolant.
It looked like it really didn't need it, but what the hell.:D
