I have just picked up a Trico MD-1200 single line solenoid controlled coolant on ebay and have a couple of questions.

I have noticed that the inside of the unit is liberally coated in coolant oil, that there is some coolant leaking from the top of the reservoir and there seems to be a small amount of coolant moving down the walls of the larger of the two tubes running to the nozzle.

Is this normal?

Thanks
