Just wondering, I've recently got a P5 with 228k on the original rad and after reading a thread or two I saw that our temperature gauges aren't reliable, after doing some unrelated troubleshooting I crossed the two electric plugs for the intake valves and the car ran like crap (big dummie ) I remembered reading that about the coolant and opened torque to check if maybe I was getting too hot and even after fixing that and getting the new solenoids in, when I climb a steeper grade at about 55 the coolant gets up to 210 (before cleaning the rad it would get to 224) I am reasonably experienced mechanically and before I go and try a new t'stat or look into the water pump impeller being erroded away I thought I would ask and see if y'all have any data on the "normal" temps. The biggest reason I ask is in the cars I have ever looked at the ect they all never got above 200 on that same hill most never got even above 196.
A little extra info...
Hot idle w/o AC: 198-203, fan on at 203-205
Hot idle w/AC : 186 to 194
Hill climb w clean rad at about 86 ambient 208 max reported temp
