Radiator Flush Cleaner
Good day fellow IRV2'ers,
I am planning to flush the radiator on my 2008 Newmar Kountry Star with the ISL400 HP diesel engine. I have seen several post on how to perform it, but do not see any mention on the radiator flush cleaner/chemical used - i.e. like Prestone Flush and Cleaner. Any recommendations for this to be used on a diesel side radiator?
