Wait for results, before you do this, you might even ask the "Been there awhile, Mature, auto parts store feller", his opinion too, about the overheat issue. I always gather all the info I can, before I go wild with new parts.
I'm more in tune with older Jeep CJs and Ford vehicles, I answer in those forums the most, however most overheating issues are common factors found in old or new rigs.
Search for vacuum leaks also, this will make you run lean.
As far as an engine cleaning, I use Marvel Mystery Oil, substitute a quart of oil for a quart of MMO, at your next oil change, Run it until the next oil change! It will also free up tappets (hydraulic lifters) that make the annoying tapping/ rattle sound in an older engine. Like I said WAIT, till you get the overheat issue straightened out.
Is your rig still in good shape, or has it been modified and stuff disconnected over the years?
