PS> Radiators weren't meant to last for 25 years without being flushed... apparently this was the original radiator, original thermostat and original fluid. I almost threw up when I drained it... mud started pouring out and it smelled like a porta-potty at a Buffet show in August!! It actually fell apart in my hands when I yanked it out. Also, all the heater hoses were cracked... not leaking fluid out of them mind you, only allowing air to seep in... PITA trying to figure out why I couldn't burp the system! It kept burping and running hot until those were replaced. Then things were a lot better. New thermostat allowed it to open right at 195 and run right at 210 and then dip down.
