Avoiding costly car repairs.

We help put your mind at rest and keep the cost of car repairs down.

Car repairs can be something you dread. Receiving a call from your service centre reporting costs of car repairs can send your blood pressure soaring!

Star Automotive and Star Tech in Poole can ease your worry and talks you through some common problems. In this article, we outline some of the most costly repairs, and how you can potentially avoid them.

Head Gasket

A common issue you may have heard of, a head gasket is a major part of an engine. A failure may happen when the gasket seal between the engine and the cylinder separates, causing unwanted coolant to enter. This can cause the engine to overheat and blow. The head gasket is designed not to be replaced which means it’s a large job to undertake.

To avoid a head gasket fail, you will want to ensure your car is regularly serviced and you have the coolant changed at the recommended intervals. This will make sure the cooling system is working efficiently. Turning the engine off when you are stuck in traffic. This will help the engine to avoid overheating. We recommend keeping an eye on the vehicle for any leaks. If you notice your coolant level is low, be sure to top it up.


This may not seem like the most expensive car repair but over a car’s lifetime it will add up. A car battery will have to be replaced every 4 – 5 years on average. The cost for a new one is between £50 and £200, depending on your make and model.

Although you won’t be able to avoid this cost, you can take steps to look after your battery and avoid having to replace it earlier. For example, turning your ignition off when waiting, ensuring you turn your lights off when parked and charging the battery regularly by going on a long drive. If you notice a light on your dashboard, get it checked out sooner rather than later.


Your clutch can wear over time. Sooner if it’s not used properly. A replacement is going to set you back around £300 – £600.

To avoid replacing it early, I would advise that you;

  1. Always use your handbrake when stopping at traffic lights and take the car out of gear
  2. Always change gears smoothly and avoid grinding them
  3. Avoid keeping your foot down on the clutch at unnecessary times

Cambelt (also known as the timing belt)

Cambelt failure is a problem we don’t often come across as it occurs more in older cars. Furthermore, cars which have not had regular servicing can be more prone to this problem. When a cambelt does fail it will usually mean the end of the life for the engine and in some cases the car. Avoid this repair by regular inspections which may catch signs of wear and tear on the timing belt early. Replace it at the correct intervals on servicing.


Suspension is vital and poor suspension will result in your car feeling unstable and uncomfortable. To avoid unnecessary repairs avoid potholes and slow down when you go over speed bumps as these could break a road spring. In addition, it can even break or bend some of the suspension.

As soon as you hear an unusual noise when cornering or going over a bump take it straight to a service centre or call us on 01202 694758. Much bigger problem can result if ignored.

Ignoring worn suspension could add up to 10m to your braking distance!

Professional advice awaits

Finally, cars can develop unexpected faults. Listen to recommendations from your service centre when having Mots and servicing carried out. Be aware of rogue traders though as they are around.
