Coolant Complications & Confusion

Nitrite Challenges Dictate an Important Dialogue

 Until Prestone introduced the first all-season, the first modern cooling system fluid back in 1927, common kitchen ingredients such as sugar, honey and molasses were used. Since 1927, ethylene glycol, with integral corrosion inhibitors, remains the major component of antifreeze/coolant (AF/C) to this day.

 When maintained and working properly, AF/C provides four key functions:

  • Controls critical engine temperature by providing efficient heat transfer
  • Prevents boilover and overheating failures
  • Prevents freeze-ups or non-starts in the colder temperatures
  • Prevents corrosion that can cause engine failure

If AF/C is unable to satisfy these requirements, the vehicle’s emissions, fuel economy, horsepower, and engine component durability will be compromised.

Implications of Higher Fuel Economy

In response to the rising cost of fuel and growing environmental concerns, the industry saw increased pressure to improve emissions and obtain a higher fuel economy. To achieve these results, significant design changes were needed.

Lighter materials were used to build engines and cooling systems, including a move from copper/brass to aluminum radiators. Early aluminum radiators were manufactured by assembly lines or through a vacuum brazing process. Later, to improve production efficiency, a new process called controlled atmosphere brazing (CAB), was developed.

While CAB improved efficiency, the process leaves behind varied levels of residual brazing flux, which can react with certain coolant inhibitors. As a result, fleets began to experience a quick decrease of nitrite concentrate with a corresponding pH spike in their coolants. This chemistry resulted in an increased corrosion rate on aluminum cool system components. This corrosion created damaging particulates which clogged filters, created pitting, and led to a dramatic increase in engine failures.

While vehicles with copper/brass radiators didn’t have this issue, vehicles with CAB brazed aluminum radiators were left vulnerable.

A Shift in Nitrite Technology Created Confusion

Heeding concerns that NOAT (a nitrite-containing Organic Acid Technology) wasn’t providing the same level of protection for aluminum systems, a number of OEMs changed their factory fill coolant from NOAT to nitrite-free extended life coolant (NF OAT). While these changes from NOAT to NF OAT eliminate issues caused by nitrites, it opened the door for another issue: confusion around the AF/C’s color.

Coolants Go Colorblind

Even after moving from NOAT to NF OAT, some heavy duty OEMs have kept coolants the same color. Unaware of the change, fleets have been incorrectly mixing coolant technologies potentially putting their fleets at risk against corrosion and cooling system failures.

 While some manufacturers differentiate coolant color with cooling system stickers, color alone is no longer the definitive measure by which to identify a fluid type.

Coolant Solutions for your Fleet

With all of these Nitrite-related issues, the good news is there’s a dialogue taking place within the industry. The goal is to develop a standardized color code for all coolant technologies to make it easier for the fleets to identify their coolant types. In the meantime, here are some solutions to make sure your fleet is covered.


Work with a Knowledgeable Technician

If an AF/C type isn’t known, the fluid should be tested immediately to determine its exact technology and the correct coolant technology to use. Make sure your technicians test for, identify, and correct any issues with your cooling system fluids. Having a conversation with your certified technician, and making sure you have the most current technology can save you uptime and repair costs.

Use a Trusted Formula

To avoid any confusion for fleet owners, Prestone clearly differentiates its three AF/C technologies: IAT[1] (purple), NOAT[2] (red) and NF OAT[3] (yellow). And for clarity, Prestone has implemented the same color codes for accompanying SCAs, extenders and test strips. Prestone offers test kit mailers that provide fleet owners a quick way to determine the best approach for cooling system maintenance.

When in doubt, flush it out!

It’s imperative that drivers and fleet owners know exactly what type of AF/C is helping run their engines. If all else fails, flush out your system and start fresh with a clearly labeled formula.

Tribute paid to Farnham man killed in Bordon crash

A Farnham man who was killed in a crash near Bordon has been named by police.

35-year-old Choudhry Muhammad Sadaqat, of Weydon Lane, died on Tuesday 25 July after being struck by an HGV. 

The collision happened three days earlier, on Friday July 21, on Green Street in East Worldham. 

His family, who are being supported by specialist officers, have released the following tribute: “Choudhry was a good son and brother.

“He has left us early to return to his Creator.

“He enjoyed life and was always ready to serve his community.  He is survived by his mother, father, brothers and family.”

The driver of the HGV, a 38-year-old man from Tamworth, who had been arrested in connection with this incident was released but remains under investigation.

Investigations into the collision are continuing.

Anyone with information about the incident is asked to call Sgt Mark Furse, from the Serious Collision Investigation Unit, on 101, quoting 44170280821.
