If you register a FREE account with Cummins QuickServe Online you can register your Engine Serial Number and have access to all the documentation for your engine. This includes what fluids to use, part numbers, service manuals, TSBs, etc.

Just choose the FREE $0.00 option.

While the Cummins Quickserve system is something I would recommend everyone get access to, it won't give you the quantity of coolant needed for your system. They only provide the engine and do not know what the entire coolant system is.

My experience is that Freightliner doesn't necessarily know either, which is unfortunate since they do install virtually all of the coolant system except the front dash heater core. Newmar just cuts the heater loop and installs the core or connects to the Oasis, neither of which would add significant volume..

In my case (which will likely not be yours) Cummins material said 4 gallons. Freightliner said 11 gallons total with the engine and all they install. Actual total system is 15.5 gallons. Interesting that the Cummins and Freightliner numbers add to basically the correct total....coincidence?

Net, your chassis manufacturer would be a better source for volume, but that may still be inaccurate.

Go visit and make friends with the parts guy at a nearby truck shop that services Cummins. Cummins makes pre mixed coolant that is good for 300k or 500k miles. I changed mine out when I bought our coach because I wanted to make sure I knew the status of all fluids. I'd check to see if it has coolant in it and then decide if you really need to change it.

In my opinion, it is vital to find out the specific type of coolant you need for your engine. If you have a "wet sleeve" diesel then you will need something specific for that engine type.
