PGPlus has provided superior heavy duty cooling system protection in every type of engine application and industry for the past 15 years.

PGPlus is the coolant of choice for many major fleet owners. It has extended the life of countless engines across a variety of industries.

PGPlus uses propylene glycol as the antifreeze/anti boil base. Propylene glycol is regarded as safe to handle which minimises risk to your wellbeing.

The additive package incorporates a hybrid of organic and inorganic additives to provide rock-solid protection for any engine’s cooling system.

Coupled with simple maintenance requirements, PG Plus provides up to 750,000 kilometres or 12,000 hours of service life. If correctly maintained and monitored, PG Plus could last the life of an engine.

Unlike lighter formula automotive-type coolants, PG Plus is suitable for any heavy duty application and meets the performance requirements of ASTM D6210 and Cummins CES 14603. Only coolants meeting these standards can provide the ultimate protection your engine needs against corrosion and liner pitting whilst maintaining the integrity of your engine’s cooling system.

To ensure your PGPlus coolant is providing maximum protection, it should be regularly tested using our 3 way test strips which will indicate the condition of the additive.

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.
