GOSS has an expanding range of the most common replacement components for this area

There are plenty of conditions that will freeze water, and this is why automotive cooling systems use an antifreeze agent – but what about Diesel Exhaust Fluid (DEF) or AdBlu?
DEF is typically made up of 67.5 percent water and 32.5 percent urea and has no antifreeze ingredients because of the precise catalyst reaction required during an SCR event.
So, in theory, AdBlu freezing in Australia is possible, so manufacturers utilise DEF heaters throughout their systems to keep the fluid from freezing and maintain a set temperature which allows for an effective reduction of NOx during catalysation.
A DEF control module is responsible for driving the DEF heater, reading a number of sensor inputs that can include the DEF tank temperature sensor, DEF supply pump temperature sensor and ambient air temperature sensor.
With data from these sensors combined, the heating element is instructed to warm the urea-based fluid within the storage tank.
The DEF heater is only one component of a Selective Catalytic Reduction (SCR) solution. It has multiple temperature inputs, running conditions and multiple modes of operation, from basic heating, thermal control, and start-up modes.
As more vehicles arrive in Australia with Euro 6 emissions standards, the complexities of emission control are growing exponentially – and likewise are component failures.
GOSS says that thankfully, it has an expanding range of parts, including some of the most common replacement components needed by vehicle repairers dealing with modern diesel emission control repairs such as DEF heaters, EGR valve assemblies, EGT sensors, DPS pressure sensors and EGR coolers.
GOSS states it is a leading provider of Genuine Alternative aftermarket and Original Equipment Supplier (OES) parts, with more than 75 years’ sourcing and developing the world’s leading OES and aftermarket parts.
