Coolant/Antifreeze Change

Coolant/Antifreeze Change

A vital part of car maintenance is to change your coolant to help keep your engine cool and stop it from overheating. The coolant is a mixture of antifreeze and water which also stops the engine from freezing in extreme cold conditions. Our highly trained technicians will drain and refill your coolant as well as disposing of the old fluid. The coolant change is also part of our Major Service.


The antifreeze that we use contains Bitrex which is very unpleasant to the taste so any child or pet that happens to find some in a container or a pool of water on the floor will not drink it, thus saving a very painful and life threatening situation.


Without engine coolant, your car would quickly overheat. Coolant is a mixture of antifreeze and water, which helps to regulate the temperature of your engine in extreme conditions.

Just like engine oil and brake fluid, coolant degrades over time, and at some point will no longer get the job done, putting your car at risk of breaking down. That?s why we recommend a coolant change every two years to keep your car running smoothly.

A coolant change will:

  • Stop your engine from seizing up in extreme weather.
  • Remove rust and deposits than can build up over time.
  • Prevent clogging and degradation of engine components, prolonging the life of your car.

Our expert technicians use manufacturer approved Comma coolant, to provide maximum protection against corrosion, overheating and freezing.

There are a number of factors which affect how often you need to change your coolant, such as car type, age and driving style. Some manufacturers recommend a coolant change after 30,000 miles, others 50,000. Check your owner's manual to get accurate information for your car.

At Halfords Autocentres, we change your coolant as part of our Major Service, a 71-point check recommended every two years.

The coolant change takes around one hour to complete.
