I have not been able to find the extreme simple green mentioned above anywhere. Can anyone tell me to find it. Thanks

I buy mine from Pep Boys, I have seen it at Home Depot and it is available on Amazon, I usually buy two spray bottles and dump them into my sprayer for routine maintenance, anything heavy get a gallon.

Smitty, good story! That would have set me off as well, long before I was an RV owner!

My cooling stack consists of a multi-core rad, CAC, Xmission cooler, AC condenser. Side mount ISM. My concern on using any kind of cleaning solution might create an undisolved dried gummy soup in areas that cannot be adequitely flushed. Especially after letting it sit for awhile. Since the idea is to open up air flow, I just use plain water from both sides.

I sent an email to Cummins questioning the normal operating temperature on my 400 ISL This is what I received, " The maximum coolant temperature (operating temperature) is 225 degrees Fahrenheit." Doesn't really address my question, but does state the upper limit.
