2001 On-Line Cooling System Cleaner

Penray 2001 On-Line Cooling System Cleaner cleans diesel engine cooling systems while they remain in service. This liquid product is an excellent alternative to in-shop cleaning for engines having only light scale and limited corrosion product formation. 2001 Cleaner is ideal for periodic on-the-road cleaning, as it removes harmful mineral scale and oxide deposits. For engines with green slime, excessive scaling, or heavy oil deposits, Penray recommends the 2015 Twin Pac.

One half gallon of 2001 Cleaner treats eight gallons.
