Routine Maintenance Radiators Gold Coast

At Currumbin Radiators Gold Coast, we know Radiators. Is your car running a little hot? It may be a simple fix or a major job but whatever the issue we are here to help.

One of the standard features of modern cars is they use a heat exchanger or radiator filled with coolant to remove excess heat from the engine. This has proved to be the most effective way to keep an engine running at the optimum temperature, but radiators need to be looked after and serviced by a good service mechanic who specialises in radiators on the Currumbin.

About radiators

When engine components started to be produced using different metals a corrosion inhibitor was added to stop electrolysis. Glycols are now mixed in with the water to form a coolant solution that protects the system from corrosion and raises the boiling point.

Some modern engines with automatic transmissions also connect to the radiator to cool the transmission fluid. Sometimes this is in the form of a closed mini radiator inside the main radiator where the transmission fluids can cool.

Although it is not so common, some vehicles require their brake fluid, power steering fluid as well as other hydraulic fluids to be cooled by the main radiator or an auxiliary radiator.

Supercharged or turbocharged engines may require their own radiator system to cool the incoming air rather than the engine, but this is a different system.

Most radiators are now made with a plastic header and footer tank connected by a series of thin aluminium tubes bonded to fine aluminium fins that transfer the heat from the coolant mixture to the air as it passes through and past them.

It is quite common for a turbulator (a fine fin, fitted inside the small tubes of a radiator) to be fitted to increase the coolants turbulence as an aid in the even cooling of the fluid.

Radiators are the main storage tank of the engine coolant system. This closed system is designed to operate with a small amount of head pressure and as we all know, water cannot be compressed and when heated, it expands. On top of the radiator is a pressurised cap on a small neck. In this neck there is a small connection where a pipe is fitted to drain any excess coolant into the connected overflow tank.

Never attempt to open a radiator cap unless the engine is cool enough for you to place your hand directly on the radiator without being burnt.

If the overflow tank is allowed to run completely dry, it may cause the coolant to vaporise causing general or localised overheating.

Why you need radiator services, including benefits

Your car in many cases is your second most expensive asset next to your home and as such needs to be looked after, so it is vital that you have it regally serviced. The two most important areas of engine maintenance are the cooling system including the radiator and looking after the engine oil.

If you neglect the radiator and your engine overheats you are very likely to cause severe damage such as a cracked cylinder head, cracked block or blown gaskets. If you are lucky enough to escape obvious damage you still will need your engine to be examined.

When the engine becomes overheated it causes the metals to expand and this can change the torque setting and loosen bolts.

The engine and radiator are equipped with sensors designed to provide a warning when the engine starts to overheat, but if the coolant level is allowed to drop, you will not get any warning simply because the sensor is not exposed to the hot coolant. This is one reason why it is important to have your radiator serviced regularly.

The coolant needs to be replaced every 25 to 50,000 km as its cooling properties will deteriorate over time. Have your system flushed with as a modern flushing compound so any impurities can be removed. This will help prevent any issues developing that may reduce the system’s cooling ability.

Then fill with new coolant that contains adequate corrosion inhibiting properties to prevent any damage to the water pump, thermostat, radiator core, radiator cap, hoses as well as the heater and cooling units.

When the vehicle is cool, drain the coolant and add a flushing compound to ensure the small passage ways in the engine are completely clear. Add the flushing agent and run the engine at idle for 10 minutes or follow the instructions on the label. Then refill with a good quality radiator coolant.

What will radiators do?

When you take your vehicle into one of the centers who service radiators on the Currumbin they’ll do a detailed examination to determine the best and most economical way to have your cooling system restored to a new condition.

  • The first thing they will do is check for leaks and to ensure that all the hoses are in good condition.
  • They will drain the radiator and assess whether it can be repaired or needs to be replaced
  • The rest of the cooling system such as the fan, water pump, transmission lines and thermostat will all be tested to ensure they are in good working order and repaired or replaced if needed.

In most cases, the radiator will be removed from the vehicle and pressure tested. This will quickly show up any areas that need to be repaired. If you have a copper radiator usually it can be repaired, but aluminum radiators are usually not reparable as the plastic tanks become brittle over time.

Once the radiator is repaired or a new one sourced it will be installed in your vehicle with all the attachments, hoses and cooling fans.

The system will be filled with new coolant and bled to expel any air and then the whole unit will be road tested

How much it could cost

As all vehicles have different radiators so the price can vary from $350 to $1000, usually the service charge is between $50 and $100, this will depend on how much work needs to be done.

The benefits of hiring a professional radiator service

  • A coolant flush will remove any internal rust or other types of corrosion that could cause your vehicle to overheat with the resulting damage
  • Replacing your coolant can extend the life of your water pump because of the specially added lubricants it contains.
  • Coolant additives are designed to reduce any foam up while your engine is running and prevent any scale forming

It’s important to remove old coolants as they lose their anti-corrosive properties and cause a build up of contaminants, they can also breakdown and start clumping, so could potentially block some of the small passage ways in the engine or radiator causing the cooling system to become inefficient.

The radiator in all vehicles while in operation is potentially dangerous; this is because it is kept under a working pressure of between 6 to 15 psi.

This means that if the cap is opened while the radiator is still hot it will cause a drop in the internal pressure with the result that the coolant liquid will boil and be forcibly ejected from the radiator in a scalding spray.

All modern radiator caps are made with a mechanism so that they cannot be opened quickly, but have a stop to let some of the pressure off before it can easily be fully opened.

Queenslanders love getting around and the Currumbin is a large area filled with many attractions, so we all need a vehicle to rely on that’s in good condition. Having your vehicle’s radiator regularly serviced along with the air-con is vital for your safety and comfort.
