Hi my name is Robert...

Want to cover some items first. Normally you would use a Fleetguard test strip or refractometer to test the coolant. IF the SCA levels are not correct then you can add an additive to bring that back. IF the freeze point is not at the proper level then the coolant should be replaced. Below is some info for you to look at for the type of coolant and it explains the SCA. Some RV'S will have a coolant filter on the side of the engine block, there is a valve on top of the housing that you shut before you remove the valve, on others there is no filter and you have to add the additive. So one type the coolant filter provides the additives, that filter is almost always drivers side mid engine you have to look up from the bottom to see the filter.

The last Cummins shop we would just drain the radiator at the bottom hose it gets most of it out, then add coolant run the engine so the T-stat opens up and then top off. I would say it is going to take between 10 and 12 gallons... Hope this helps... Robert

The dealer is taking it to Cummins today for a diagnostic. It is a substantial purchase for us and with this issue I am looking for ways to insure I am not getting a lemon. the unit only has 36,000 miles. I know Cummins has a good name and I have negotiated a good price. Just wondering what I can do to insure the motor is RIGHT when the deal goes through.
