Hello all, I again am back to diagnosing coolant issues with my D6b. Yesterday I fired the ole girl up for a few property repairs, after full checks, Fuel, Oil, Coolant, and gear oils. The machine fired up instantly after sitting for a year and a half and I made progress for about 45 minutes when I notice fluid on the hood near the radiator cap, and instantly I instinctively looked at the temperature gauge noticing it was running about 220-230 degrees F. I immediately lugged the machine to it's parking place and shut it down. I noticed coolant inside the front portion of the engine bay, outside the front of grill, on hood and dripping down to the ground. I instantly thought, check the oil and breather for coolant and contamination. None was found. only in the places first noticed. I put a brand new thermostat in year before after doing head work on the machine. For the first year after the head work the radiator stayed completely full until today when I had to add 2 gallons of coolant. I'm not certain I have a head issue but the situation didn't occur until I began running higher RPMs while pushing brush and trees across the property. I've looked back through all my diesel mechanic books but never experience this before with a diesel. Reminds me of a car on a long family trip the starts boiling over like a thermostat stuck. Any other ideas?
