Ok, update on Radiator tests i did this evening.
I started the motor and let it idle for 10 mins, checked gauge and it was just under 210. steady. Used IR temp gun and on input it was 190 on the hose where it enters radiator and 172 where it exited the radiator on the hose. it was pretty constant around the radiator (at least were i could hit which was not a huge spot.)
Next i pressed the gas and held it about 2k rpms for about 2-3 mins and the temp started going up, it went half way from 210-and the red. Temp readings at the input to radiator was now 220 and exit was 205.
I didnt get to drive it and test, but thats what i got so far.
Also yes the electric fan was running, and yes the clutch fan kicked in when started warming up.
My guess, and only my guess, is that the radiator is cooling, but may be clogged and not letting enough water flow threw the engine? am i close?
What should i try next to test. Looks likes it going to be a pain to remove radiator so dont want to do that except for last case.
I am planning a trip cross country in late July to Colorado, so need to get this fix up. I appreciate each and everyone of your thoughts and ideas.
I have been on many forums on many different things, and the RV and Boat forums always have the best people and most help, RV.net is great.
