I have a D6C ( ser#10K7399) has been running fine. Usually the temp gauge barely gets into the green. Went to use it a couple days ago and after running it for 30 mins noticed it was running hot.
I shut it down and let it cool off overnight. Next morning I took the radiator cap off to add coolant, noticed a little oil film on the cap. Added a gallon of
coolant to fill it. Started it up and within 15 minutes it was getting hot again! This time when I shut it down I had some watery oil spurting out the overflow tube.
So ... I am assuming I have a bad oil cooler and that is how oil is getting into radiator?! No water in crankcase.
But... would the oil cooler cause the overheating so fast ? I'm going to get a new thermostat for it and also wondering if the water pump went to hell ?
Any thoughts ?
