My 2011 - Sk170 has 2800 hrs and started a hydraulic pulsing this morning. I checked the tank and it was way over full and had a green tint to the fluid. This started explaining the coolant loss I've been experiencing for a year or so with no explanation, puddles, or smell in the exhaust. Has anyone with a similar Kobelco had an issue with a radiator which i assume cools hydro fluid as well, and can tell me how they remedied the issue of coolant getting the hydro system? I appreciate any help or advice. Thank you.
Can you add a picture of what you were seeing and also your serial number
