I never did get around to doing the citric acid flush on my SD, seeing as how as soon as my sore back got better I made it even worse than before, putting up cabinets in my kitchen.
HOWEVER, I did today decide to pull the thermostat (3 mos. old) and see what difference it might make. HUGE difference, went from running at ~100 to actually running a little under normal, just over 80, only hits 85-90 on the highway (70 mph). QUESTION 1: what have I learned here? Anything? QUESTION 2: I now have a slight leak at the mating surfaces of the T-stat housing. Will this just be a case of pulling it apart again and cleaning it up with sandpaper?
