I am going to buy a mid ninties PSD and would like any input on what to looking for as far as the PSD. I have heard about cavitation and know how to check the coolant, but what about any maintenance prior to the current coolant . I'm a little apprehensive about buying one due to the fact that I don't know that much about the PSD and this truck is going to have to last quite a while. As far as checking the coolant what else should I be looking for?

Any advise greatly appreciated.
