ok i can not finding how to add coolant or check it for the spindle its a old vmc40,1986 ive followed the to hoses from the pump/radiator box on the right bottom all the way to the top of the spindle and out the bottom and back its tottley closed??? isn't there sopost to be a coolent bottle?? and no in not confusing this with the flood coolant system. chips i know your mech is about the same year any idea??
if your looking strait at the mech an the right hand side on the bottom of the sheet metal is a box with a radiator facing down theres a small pump in there too, it thats your pump for the spindle maybe it was modifyed??
