Radiator and Cooling System Service

Don't be that car, stuck on the side of the road with steam pouring from under the hood. We will give your radiator and cooling system a well deserved service.

A fully functional and efficient cooling system circulates coolant to reduce heat around your engine. It is essential in preventing overheating, therefore reducing wear and tear of engine components.

If your dashboard shows your car is running hotter than normal or you are leaving puddles of coolant where ever you park, it is time to have your cooling system checked out.  View our AutoFacts Video to learn how your cooling system works.

A regular radiator flush will prevent rust and debris from building up which creates congestion in your cooling system. This congestion will cause your cooling system to run inefficiently, leading to overheating of the engine and ultimately worse issues such as warped or broken engine blocks, corrosion or even engine failure.

When you visit your local Repco Authorised Service centre, trained and experienced mechanics will flush your radiator, using a solution to clean all channels of build up. When the cooling system is clean the solution is drained and the new coolant added. Your car's cooling system will be running like a dream.

If you suspect your radiator or cooling system is struggling it is time to pop into you local Repco Authorised Service centre. We ensure your radiator is flushed at least once a year, as recommended, and we use quality products such as Penrite's radiator flush.


New car? No worries

Every Repco Authorised Service centre is fully qualified to service your in-warranty car and maintain the log book servicing schedule. You’ll enjoy the value for money and friendly service you expect from a local and trusted independent service centre, combined with the reassurance of the nationwide warranty backing provided by Repco Authorised Service.


Radiator and cooling systems - everything you need to know and more

The role of the radiator, cooling system and coolant in a car is to dissipate the heat, therefore reducing the stress placed on the engine. This heat is produced when chemical energy (fuel) is converted into the energy that drives the mechanical elements of the engine to power the car. Unfortunately only approximately 20 - 30% of the energy produced from fuel is used to power the engine, the remaining 70 - 80% is converted to heat. This is why an engine gets so hot. 

A car cooling system is made up of five major components;

Radiator: Helps to reduce the heat of coolant. It is made up of a series of tubes designed to catch the wind and dissipate heat before the coolant is pumped back into the cooling system.

Water pump: Think of this as the cooling system's heart. It pumps coolant all around the engine.

Cooling system hoses: Carrying coolant between the thermostat, engine and heaters, these reinforced synthetic rubber tubes have been built to withstand chemicals, heat, vibration and more.

Thermostat: Regulates the delivery of the coolant to the engine. When the engine is cold the thermostat is closed. As the engine warms up it begins to open until the engine is hot and requires a constant flow of coolant to maintain an optimal temperature.

Fan: Assists the thermostat and coolant to maintain a consistent engine temperature. Controlled by the thermostat or the engines computer, the fan will automatically turn on or off as required.
