Is Your Car's Cooler in Need of a Flush?
Your car or truck relies on a sophisticated cooling system to make sure that the engine block and ancillaries are kept at an optimum temperature so that they work as efficiently as possible. But did you know that there is a secondary cooling system on most vehicles today that aims to keep the oil at an optimum temp as well? If you didn't realise this, it pays to keep a close eye on this system and ensure that it is serviced if necessary. What could go wrong otherwise?
The Oil Cooling System
If you open the bonnet of your vehicle and have a look at the very front, you may notice a miniature radiator sitting next to the primary component. The large radiator handles the coolant or antifreeze, while the smaller part takes care of all the engine and transmission oil. Both components work similarly, but the oil cooler also relies on a steady flow of coolant within. The coolant flows through miniature tubes next to the pumping oil, which helps suck the heat out of the oil before sending it back to work.
When Trouble Arises
Most of the time, this system will work perfectly well without any intervention. A pump will circulate the oil through the system, while a separate pump will take care of the coolant/antifreeze mix.
Given time, however, tiny particles can build up within the fluid. Due to friction and harsh operating conditions, these particles may wear away from metal parts or rubber hoses. Eventually, they may coagulate within the cooler matrix, which could lead to a blockage of some kind. When this happens, you may notice that the temperature gauge on your dashboard begins to rise, and you may also see a warning light.
Action Required
It's best to take action as soon as possible in this situation and take the vehicle to a mechanic. They will then flush the coolant and oil chambers to get rid of any built-up contamination. They will also conduct a visual check to look for any signs of wear and tear or the potential to develop a leak. Sometimes coolant and oil may mix within the component if any cracks or leaks have developed within. This situation needs to be avoided at all costs as it can certainly lead to overheating or substandard lubrication.
Paying Attention
Remember, your oil cooler will need to be serviced every now and then if it is to perform as expected. Talk with your mechanic for further advice and if it's been some time since they looked at this part. Contact a car service near you to learn more.
