Coolant is vital for the smooth operation and long life of every engine we produce. Using Perkins Extended Life Coolant (ELC) extends the time needed between coolant changes and is the recommended product for doing so. It also maintains your warranty and protects your engine and cooling system.
The primary function of an engine coolant is to help remove the heat that is generated in the engine block from the combustion of diesel fuel. Typically in heavy duty diesels, up to one third of the energy produced needs to be removed by the cooling system.
Coolant is a combination of a heat transfer medium, typically high quality water and glycol, various corrosion inhibitors and functional additives depending on the coolant type.
In addition, the coolant has a protective role. It guards against corrosion of the engine components and protects the engine from freezing – with potentially heavy financial implications – when temperatures fall below zero. Equally, it cools in very high temperature environments; this is important because our machines operate from the hottest parts of the planet to the coldest. It lubricates the water pump and maintains general chemical and oxidative stability to ensure efficient functioning of the cooling system.
Perkins ELC is supplied in 20 litre and 200 litre drums, and is premixed containing 50 percent ELC and 50 percent totally purified water.
You need top performance. That is why our ELC meets or exceeds ASTM D4985 standards for heavy duty, low silicate anti-freeze/coolants and ASTM D3306 for automotive applications, TMC RP-329 for extended service, ASTM D-6210 for fully formulated coolants and SAE J1034 for coolants.
Our ELC is designed to lower your owning and operating costs by extending the intervals between draining and replacing the coolant up to 3000 hours or 3 years. This reduces the cost of coolant and additives by as much as 80 percent over other, conventional non-Perkins heavy-duty coolants. Our ELC provides maximum protection of metals including; aluminium, copper, brass, steel, solder and cast iron.
It’s always worth bearing in mind that safety precautions must be taken when checking, adding or changing coolant.
