For 30 years, diesel engine users have been told that cooling system problems caused at least 50% of all premature engine failures. Now, suppliers and users alike are concerned and generally in the dark on the exact changes in methods necessary for engines and cooling systems to meet 2002 and beyond emissions regulations as well as retrofit requirements possibly back to 1986 models.

Most major engine manufactures are expected to use Exhaust Gas Recirculation (EGR) systems on diesel engines to help them meet stricter EPA emissions effective in 2002. EGR will affect oil, oil drain intervals, filtration, etc. because of additional heat loads. That additional heat must be controlled by coolants and the cooling system. If not, premature engine failure will increase dramatically more than the old 50% number. No matter what new products or methods are used there is one irrefutable fact that stands out: cooling systems must be clean and kept clean to do their job effectively. The old adage is still correct - Good Cleaning means Effective Cooling - and without effective cooling, no engine will stand up under the new EPA regulations.

The patented closed system cleaner formula is converted from a powder to a pellet form and enclosed in the cooling system cleaner/filter by the Enviro-Cool^TM manufacturing process. The Enviro-Cool^TM Cleaner/Filter is a spin-on filter that is installed in place of the inhibitor filter which allows the pelletized cleaner to dissolve and enter the coolant slowly...
