I've been having the issues with my coolant temps for the last two weeks. First the heater core hose blew, simple fix on the side of the road...I thought.
After replacing the hose, topping of the coolant, I had high temp problems. I was in the 210-215 range cruising. I figured that I didn't tighten everything down, re-checked it fine. I checked the radiator hoses, not as hard as normal. I got a pressure tester, It was loosing a lb per 3 min. Not that bad. Checked everything, looped the heater hoses, and turbo, still loosing pressure. Found the TB hoses were hard as rocks.
I ended up replacing the heater hoses, TB hoses, Turbo hoses, and radiator hoses. I have correct pressure, but now my temps are all over the ####ing place.
Tonight its about 65* out. I was at 80 on the interstate, 192*. It would randomly jump to 204-208*. NO difference in load. Just cruising.
It has been getting as high as 218* randomly. I would be cruising, then spike. If I floor it rpms go up, temp goes down.

All new hoses, new cap, thermostat, flush. Currently running distilled water and water wetter only. Temps all over the place. RPM's go up, temp will drop 90% of the time.
