One of the most common causes of breakdown on Australian roads is the engine overheating.  Most of the time the cause is a fault in the cooling system.  Modern engines run hotter, with higher pressures and power more components so they require a highly functioning cooling system.  These modern cooling systems work hard; and they don’t take too kindly to neglect. A thorough check of the cooling system is a significant part of every service that we carry out.  Here is a quick breakdown of just three of the checks that we do with an explanation of why we do them.

We take a sample of coolant from the radiator and test the quality and concentration of coolant. Aged, contaminated, or diluted coolant offers less protection against corrosion and is not as efficient at cooling your engine. The correct concentration of coolant raises the boiling point of the water in your radiator - essential for proper circulation and cooling. The coolant test as well as referring to the manufacturers’ guidelines allows us to advise when a system flush and coolant replacement is due.

To test for leaks a tool is used to pressurise the whole cooling system and check that it can hold the pressure.  A failed pressure test means that there are leaks which might have otherwise gone undetected.  This test can also help diagnose weak hoses and check that the radiator cap is able to hold the correct pressure.  A fatigued radiator cap will allow coolant to leak when the engine is running and it won’t be maintaining the proper pressure of the system when the engine is running either.

A strong stray current taking a shortcut through the coolant can cause modern radiators to corrode quickly.  This accelerated corrosion can cause leaks within months even in brand new radiators.  It’s called electrolytic corrosion.  An unacceptably high current just means that an electrical component, such as the headlights for example, are not properly earthed.  This simple fix can save a radiator.

When it comes to the cooling system it is essential to pick up on little problems early, before they become big problems.

If the cooling system fails it puts your engine at risk.  Regular cooling system servicing and maintenance will give you the best chance of staying in the fast lane; not stranded on the side of the road.
