Thanks for the replies. No oil/coolant contamination visible on the dip stick or in the coolant. Will follow up on the air compressor suggestion.

Just picked up a 91 dump truck that has been sitting a while. After about 10 seconds of running, it started leaking coolant from the resevoir cap. Shut the engine down and upon removal of the cap, the system spewed about 1/2 gallon of fluid under high pressure. Engine was stone cold. Any help trouble shooting this would be appreciated. Engine is an EM7-300.
