No engine cooling system is maintenance free. Over time coolant can degrade through dilution with water and additives can deplete. Foreign substances can enter the cooling system, affecting the coolant chemistry. Products can get mixed, making testing and servicing difficult.

Coolant is designed to perform in the form it was manufactured. Changes can have disastrous results for an engine.

Cooling system maintenance is one of the key factors in preventing or identifying problems. Cummins Filtration provides the most comprehensive cooling system product range with support products that help test, service and repair cooling system fluid.

If your system is maintained effectively you will get better performance from your engine and experience less maintenance and downtime.


Coolant Filtration

Contamination is one of the key contributors to pump seal failure. Using a coolant filter can reduce the risk of pump seal failure by up to one third. A coolant filter removes harmful contamination that enters the cooling system via poor quality water, internal component wear or inbuilt particulate like core sand from the manufacturing process.

Coolant filters are a quick and easy way to regularly service coolant and replace spent additive, and to protect the system against corrosion and other problems like over or under-dosing.

Take the guesswork out of servicing your system with Cummins Filtration coolant filters and be confident that your equipment will perform the way you expect.


Test Strips

The only correct way to understand the condition of coolant is to test it. Regular testing can identify trends that may be leading to equipment damage.

Cummins Filtration’s easy to use dip and read test strips offer the simplest means to check what condition your coolant is in and help identify any issues before they result in major failures.

Cummins test strips are available for PG Platinum and PG Plus.

Liquid Additives

Cummins Filtration uses two types of additives in our coolant formulations.


Liquid additive for PG Plus

The additive package for PG Plus contains nitrite and molybate which are excellent for controlling liner pitting that can occur on engine piston sleeves. The nitrite chemically transforms the oxide present on the steel liner into a harder material. In doing so, the nitrite in the additive depletes and requires replenishment over time.

Checking the coolant with test strips indicates the level of additive in PG Plus and provides information on how much additive is required to be added to the system. In systems up to 80 litres the appropriate filter can be used to administer additive, however larger systems require larger quantities of additive which is why Cummins Filtration produces liquid additive to service these systems.

Supplemental Coolant Additive (SCA) is necessary to boost additive levels in PG Plus, enabling your system to operate at optimum performance levels while providing maximum protection.


Liquid additive for PG Platinum

The organic additive package in PG Platinum provides protection differently to PG Plus. The additive components in PG Platinum form a bond with the surface of the metals and other materials within the cooling system and are not depleted in the same way. Hence PG Platinum does not generally need to be topped-up with SCA during its service life. This creates a much simpler servicing process and eliminates the possibility of dosing errors.


​Refractometers

Low glycol levels in coolant will reduce the boiling point and have a detrimental effect on the engine, particularly in hot spots around the head.

Refractometers provide a more accurate means of measuring the glycol content of engine coolant. It is important to maintain glycol levels within the limits of the specification. Different products may require different refractometers depending on their additive make up.

Cummins Filtration provides two types of refractometers; one for PG Plus and one for PG Platinum. The appropriate unit must be used with the correct coolant.


Expert assistance for cooling system analysis

Whilst test strips and refractometers can give an indication of a coolant’s condition, any issues that are outside the scope of these areas may require further investigation. Laboratory testing of coolant samples can give a better indication of the true state of coolant.

Cummins Filtration offers expert assistance with cooling system analysis. We understand the importance of cooling system health and its impact on the success of your business.

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.
