Radiator flush

No-one wants to be "that car" stuck on the side of the road with steam pouring from under the hood.

An overheating car isn't just caused by summer weather. Your engine produces a lot of extreme heat and it's the radiator and cooling system that stops your car - and you - from being damaged by all that heat. A special fluid called coolant is added to your system which also prevents liquids from freezing and protects the system from corrosion as well.

How do I know I need a radiator service?

If your dashboard shows your car is running hotter than normal, your vehicle is overheating or you are leaving puddles of coolant wherever you park, it is best to have your cooling system checked over by a professional mechanic.

If your vehicle is showing these symptoms, come and see the team at Marjac Automotive.

And we can perform a well-deserved service on your radiator and cooling system. Our qualified mechanics will perform a radiator flush, using a solution that clears the system of build-up. When the cooling system has been cleaned out, the solution is drained and coolant replaced, your car's cooling system will be running like a dream: a radiator flush might be just what your car needs to bring it back to peak performance.

What are the benefits of a radiator flush?

  • Your radiator will be more efficient - and it will last a lot longer.
  • Your engine will be more efficient and have an increased life expectancy.
  • Engine performance and power will be boosted.
  • The water pump will last longer due to better protection and lubrication.

How often should I get a coolant system flush?

Your car's log book provides an outline for how often to flush your cooling system. It is usually suggested that you have your system flushed every two years or 40,000 km, whichever comes first. However, the size of your engine, local seasons, the age of your existing coolant, and the total km driven can all have an effect on how regular you'll need to replace the coolant in your radiator.

At Marjac Automotive, you can request a full 65 Point Vehicle Inspection for free as part of any minor, major or log book service on your vehicle. This includes checking the level and condition of coolant in your system and the written report will tell you if we feel a radiator flush, coolant replacement or any repairs are required to maintain the safety and performance of your vehicle.

What happens if I postpone a radiator flush?

Given time, rust and scale deposits accumulate and the whole system becomes choked and not so effective at cooling and protecting your car. This build-up of rust and debris can damage the important parts of your cooling system including your water pump, radiator, hoses and thermostat, this can reduce the lifespan of those parts and lead to expensive repairs or replacements in the future.

Can I flush the radiator myself?

While there are a lot of places offering advice on how to flush a radiator yourself - we don't endorse it. Modern vehicles can be complex and mistakes like incomplete flushing or changing the coolant in your vehicle without flushing can stir up the deposits and cause blockages in your thermostat or radiator. It's advisable to have your systems examined regularly by a qualified mechanic, and properly flushed before being refilled with the right type of coolant, the system purged of any air pockets, and then the whole system expertly reviewed again to ensure the full working order and to prevent any costly breakdowns in the future.

Radiator coolant is toxic and needs to be handled very carefully. It smells sweet which can be inviting to children and pets so proper storage is very important - having a professional do this job for you means not handling or having dangerous chemicals around your house. Dangerous coolant also needs to be disposed of in the proper manner, professional workshops can have the coolant recycled or properly disposed of to save the environment.
