Why Does My Car Keep Overheating?

All modern cars have a cooling system that comprises a water pump, a thermostat, a radiator and piping. It’s all responsible for circulating coolant around the engine to keep everything cool and with a specified temperature range. If your car overheats it’s likely one of these components has failed.

Prevention is always better than a cure and there are several things you can do to reduce the likelihood of your car overheating:

  • Annual servicing will check that your cooling system components are working correctly, as well as checking the concentration level of the coolant and antifreeze to ensure smooth operation throughout the year
  • Check your coolant and antifreeze levels throughout the year at regular intervals and top it up if necessary. If you find you are topping up regularly there may be a leak somewhere so get it checked out before the cooling system fails and it’s a more expensive fix.
  • Check if the water pump for your make and model has a manufacturer-recommended replacement interval and make sure it’s changed as advised.
  • Only ever use the correct coolant and antifreeze for your make and model. Not doing so can cause serious problems.
