Engine issues inevitably cause problems in the cooling system, and vice versa.

The most important function of the coolant in your cooling system is to transfer heat from the hot metal surfaces to the radiator. If the metal surfaces suffer any type of contamination this ability is reduced, putting excess strain on oil and engine components and ultimately resulting in premature failures.

Whether it is rust or other types of corrosion, oil or fuel contamination, or even scale from using poor quality water, Cummins Filtration has cleaning agents for your cooling system that will restore it to like new condition.

Our Restore and Restore Plus products are designed to treat specific kinds of contamination issues and are effective in assisting your cooling system to operate at peak efficiency.

Simple to use and effective, Restore and Restore Plus will bring your cooling system back to life without harming metal surfaces, gaskets, hoses or plastic parts.

FAQS

What is the proper chemical SCA (supplemental coolant additive) concentration for my engine?

For PG Plus, a chemical concentration of 0.3 – 0.8 UPL (units* per litre) should be maintained in your cooling system at all times. Or 3 – 8% by volume. (1 unit = approx 100ml of liquid additive.)


Is your SCA DCA4 inhibitor compatible with Nalcool/Penray additive?

Cummins Filtration's SCA is compatible with Nalcool/Penray chemicals. When testing a mixed coolant for SCA content, always use Cummins Filtration's CC2602 test kit for proper chemical concentration measurement.


What is the difference between DCA2 and DCA4?

The difference between the two forms of DCA is the chemical makeup. DCA2 is a borate/nitrite-based additive. DCA4 is a phosphate, nitrite and molybdate-based additive. DCA4 is recommended by many OE manufacturers, including Cummins, Navistar, Ford, John Deere, and others.


My cooling system is contaminated with rust, scale, oil or grease. What is the solution for these problems?

Cummins Filtration's cleaner Restore Plus eliminates rust, scale, oil and grease with its special acid-based formula.


​How much DCA4 should be added at service intervals?

It depends on system capacity. If no test results are available, use 1% to 2% of liquid additive or 0.1 to 0.2 units per litre of coolant.
 

What is the probable cause of nitrite leaving the coolant while molybdate remains at normal level?

This condition is caused by excessive exhaust gas leakage into the coolant and/or topping off the additive package with some other nitrite-free additive.


My cooling system is contaminated with silicate gel. Can I remove this with plain water?

No. Cummins Filtration recommends using its alkaline-chelating cleaner Restore.
