Yes make sure black tank is full and white tank a 1/2 inch above line. Replace radiator cap if it is 30 years old. After a plenum pull recently I filled it and then noticed temps higher than normal. It was down 2-3 pints.

Yes you must pull radiator every 50,000 miles to clean it. Here in FL sand jams in the fins from following other cars too closely. It is surprising how much it scoops up.
