Brad: there is a drain on the side of the block of the 8V92 series that will drain a few gallons once the radiator is drained.

There are two categories of coolant; standard and extended life. Given your circumstances I would suggest going with an extended life. Yes it will cost more but it will last long enough to save you the extra materials cost and labor cost. You need to look carefully at the Detroit Diesel spec's for coolant for your engine and then carefully compare with other brands. No one can tell you exactly what you should do, at best they can tell you what they have done, but their circumstances may differ from your own and make another solution more sensible for you.

I chose ES Compleat OAT as an extended life coolant that should last longer than I will given the miles I drive. Do not confuse that with a NOAT coolant which is unacceptable in our 2-stroke engines.

Do not pay any attention to color, green coolant is supplied according to a variety of spec's, only a few of which are acceptable in your engine. DO pay attention to the spec's. I personally am not comfortable with a coolant supplier claiming that their coolant is equivalent to a particular spec. In my mind, unless the container states it meets the necessary spec I'm not buying it. Others will feel comfortable buying one that claims it is equivalent, that doesn't make either them or me wrong. It is a matter of studying the subject and reaching a conclusion you are happy and confident with.
