Coolant service cost
Was thinking about having the coolant system flushed on my mh. Called the Cummins Diesel place locally and they told me it would be $1,200. I quickly said let me think about it. Has anyone had this do...

Brett Wolfe posted his change procedure a number of years ago and I'd highly recommend it. I had a 2008 Allegro Bus with a Cummins ISL that I changed out the coolant for one of the newer OAT types. My only difficulty was that the unit did NOT have a coolant drain, so I disconnected a lower radiator hose at a convenient location. First drained then replaced with tap water, Ran it until temps came up, pulled the hose again, refilled again with tap water, and drained again. Finally, put the correct amount of UNDILUTED OAT coolant in, and filled it to full with Walmart distilled water. I did have a bubble in it on the final fill, but when it worked it's way out, a fill to the full point with distilled water was all it took. Brett's procedure works.
