I have a 2013 Vertical Doosan DNM500 that has thru coolant capabilities. A floor guy noticed coolant dripping out from around the covers of the spindle and I took the covers off expecting to see a busted hose. There's nothing busted, and while running thru coolant nothing leaks. As soon as you shut the thru coolant off, coolant gradually starts leaking out of a bunch of different places (can't really tell where the actual leaks are). Any body else ever run into something like this? Can't seem to find the schematic of the spindle and the lines going to it.
