Automatic Repair Disaster Prevention Maintenance of Your Cooling System


One area of ​​car service that is often overlooked is the vehicle's cooling system and this neglect can have catastrophic consequences. There are several reasons why good maintenance and maintenance of the cooling system is so important. The first reason is that current cars tend to be designed "on the edge" with very little margin. This is especially true for the cooling system. In order to lighten the weight of a car, to make it more energy efficient and to increase the consumption of gasoline, everything is smaller. Cooling systems now contain about half of the coolant in cars several years ago. Modern radiators are also much smaller and lighter, so there is much less room for error. Previously, cars could have half of the heatsink plugged in and work properly, but this is not the case today. In fact, with some cars today, if they have only a quarter of a liter of coolant, they can overheat. Everything must be perfect for the system to work properly.

Another problem is the trend toward extended life-cycle coolants. Today, in an effort to respect the environment, all manufacturers install extended life coolants that probably do not need to be replaced as often. In fact, some manufacturers do not recommend replacing these coolants with a maximum speed of 150,000 miles. It can work very well in the lab, but it does not work as well in the real world. In normal operation, coolants tend to become acidic over time. When this happens and you have an acidic fluid in a cooling system, it starts to set up a process called "electrolysis" that can damage your engine and other parts. One of the first components that can be damaged by this process is the heating core. These units have the thinnest metal in a car. Repairing or replacing a heater can be very expensive. Ask one of your friends who had to fix it. And if this component has been affected, it is likely that other components will also be degraded. The main radiator of your vehicle may also be damaged by an acid coolant. Replacing a radiator in a car is also an expensive repair. Cylinder gaskets are another area that can be negatively affected by this process. In the case of a cylinder head gasket, the electrolysis corrodes the aluminum surface of the cylinder head, which destroys the sealing surface. Once this happens, the seal can no longer hold the seal and it blows. If this happens, there will be expensive repair work in the store. Even the hoses of the cooling system can be absorbed by the problem of electrolysis. A pipe may look perfectly thin from the outside, but the interior surface may be eroded and, if a pipe is blowing, it may also cause major repairs.

Although manufacturers do not recommend replacing coolant for 150,000 miles, a good auto repair shop will be able to test the coolant acidity level. If it's out of tolerance, it can be emptied and changed before it becomes a problem. This service is much, much cheaper than repairing a blown head gasket. Make sure your mechanic checks the acidity level of your coolant when performing routine servicing or tuning on your vehicle. It just takes a minute to stick a test strip in the coolant and your mechanic can show you the results. This simple test could save you a lot of money.
