The engines in many of the vehicles on the road today are smaller than they used to be, as well as being far more efficient. But they also produce a great deal of heat. The cooling system is responsible for maintaining the engine at an acceptable operating temperature. The radiator protects your engine from over-heating during hot summer months by circulating coolant through the engine. If there’s a block or a leak, your engine can quickly overheat and your vehicle will break down. The number one cause of coolant leaks is corrosion due to a lack of routine maintenance. Coolant leaks are also caused by old or cracked hoses or a hole in the radiator itself because the radiator metal core is thin and easily damaged.

At Hitech Auto Electrical and Mechanical Auto Service we recommend having your coolant and radiator system professionally inspected at least once a year. If your vehicle is over-heating or losing water you should give us a call or drop into our service centre. Our trained technicians will inspect your entire cooling system and if any coolant leaks are detected, we can repair them or replace the damaged part. At Hitech Auto Electrical and Mechanical Auto Service we service cooling systems in an environmentally safe way. We pump out the existing coolant and properly dispose of the used coolant according to Australian standards. We service the cooling system with a conditioner, which cleans out the system. We then refill the system with new anti-freeze, adding a coolant system sealer when recommended. The last step of the process is to pressure test the system to remove all air pockets, and to make sure that the cooling fans are functioning in a timely manner.

Radiator Coolant Flush

A flush and fill is a critical part of routine maintenance. Anti-freeze (coolant) is very caustic. Left in the radiator for too long, it will begin to corrode the metal, and cause a potentially disastrous leak. Over time, the coolant and anti-freeze chemicals in an engine (used to prevent the engine from overheating) deteriorate under usage. This causes them to lose their resistance to freezing and boiling. Additionally, engines contain quite a number of parts in the cooling system that are prone to rust. This, along with other components corroding, can cause the system to become clogged over time. In extreme cases, a cooling system blockage can occur. To prevent this, a cooling system flush is recommended. It flushes all the old chemicals out of your car’s engine and removes any particles.
