Coolant leak on Cummings Diesel engine
We are sitting up in the north Georgia mountains and were preparing to head south, when we noticed a small coolant leak. We have a Cummins 370 ISL engine with a side radiator. The leak appears t...

Klueck, it sounds like the leak is rather small. As long as you have plenty of fluid in the coolant box, you should be fine.
We had a leak from the heater hose back in Sept. of 2012. Apparently, there was a shield that was missing and the hose rubbed against the engine causing a small hole that grew bigger. Amazing that it took just over 50,000 miles to appear. Anyway, we were 60 miles from Cummins Central Power in Kansas City, MO, heading back to TN. I went to Walmart and bought 10 gallons of antifreeze and put in 7 gallons.
We drove cautiously the 60 miles while I watch my temp gauge. It stayed at the correct temp the whole way. When we drove up to the Cummins facility, the tech came out and we had a steady stream dripping from the hose. We still had fluid in the coolant box.
They replaced the hose by splicing it (at least a 35 ft, hose) and I needed a new coolant box as it has lost it's 'pressure' feature. Cummins in Kansas City did a wonderful job and worked us in without an appointment. We stayed in their free lot with electric and water connections the day we arrived with an early morning appointment the next day. Since the job took until late afternoon, we stayed again the second night so we could leave fresh and early the next morning.
If fact, I had such good service from them that I planned my BIG 60,000 mile service this past Sept. (2013) when passing through Kansas City heading back to California (engine and genny service).
Safe travels,
MM.
