Coolant change on 96 Monaco Exec Cummins M11

[vacuumbed]

Hello everyone,

Has anyone attempted this at home? I changed my coolant filter once, but I have never done the coolant. I am not able to tell what the capacity is or where the drain plug is.

This is a 96 Monaco Executive diesel pusher with the Cummins M11.

Thanks in advance.

*Update*

I found the drain plug on the side radiator. It is on the tank closest to the front of the RV.

I bought Fleetguard coolant. They sold me the blue stuff and said it is okay to mix it with my old green coolant.

You may have to pull a hose for draining and I only use CAT coolant with mine. Cummins surely has one or compatible, also.

Not a difficult job. Yes, you do need to determine total system capacity and make sure you have a diesel-compatible coolant.

If you want the step by step instructions, let us know.
