Alternator Repairs in Bolton

What is a Car Alternator?

Your alternator keeps your car’s battery charged, allowing you to start your vehicle and power your electronics. It uses your car’s drive belt to convert the mechanical energy from the crankshaft into electricity. If your alternator fails and stops charging the battery, you can struggle to keep your car moving. That’s why you should always book an alternator repair as soon as you notice a problem.

When Do I Need to Book an Alternator Repair?

You should book an alternator repair near you if you notice any of the following warning signs:

• Your car is difficult or slow to start
• You hear a whirring, whining or squealing noise from the engine
• Your car's interior and exterior lights look dim, blink erratically, gradually fade, suddenly get brighter or don't come on at all
• Your battery warning light comes on
• Your speedometer stops working.
• You can smell rubber burning.
• Your car fails a multimeter test at a garage.

How Much Does an Alternator Cost in the UK?

Alternator Repairs cost between £100 and £700 in the UK. The average is between £150 to £300 and, while refurbished car alternators ar available, they don't offer that much of a saving.

What Causes the Need for a New Alternator?

Your alternator is a very durable component, but you can end up needing a replacement if either of the following happens:

• The brush, a component which maintains constant electrical contact with the spinning alternator, becomes worn.
• Your voltage regulator fails. This makes sure that the electrical charge is passed to the battery at the correct voltage.

Can I Fit a New Alternator Myself?

Yes, you can fit a new alternator yourself. However, you should not attempt the process unless you are experienced and know what you are doing. Not only can you cause extra damage to your vehicle, but a live battery can also give you a nasty shock if you don’t disconnect it properly.

To fit a new alternator yourself, you must follow this process:

1. Disconnect the battery. You must disconnect the terminals in the right order and ensure it is completely disconnected before continuing.
2. Disconnect the wires from the back of the alternator. Label the wires as you go so you can reconnect them all in the right place.
3. Remove the belt from the pulley.
4. Remove the bolts. These connect the alternator to the bracket. Once these are loose, you are then able to get the old alternator out of the car.
5. Make sure you have the correct replacement alternator. The last thing you need is the wrong sized part.
6. Reverse the removal steps to install the new alternator.

How can you save money (and the environment) while you drive?

As every garage owner will tell you, there are some tried and tested ways to cut down on your petrol costs (and consumption) while you’re out and about in Bolton or beyond. One is to shut your windows. If you can hear that wind noise in your car it’s costing you more to drive. This is because the car becomes less aerodynamic and has to work harder to motor along. Removing a roof rack will improve your fuel efficiency for the same reason. Another useful tip is to combine short trips into one; each time you drive after your car has been parked for a while the engine will be cold and need to use a lot more fuel for the first 5 miles or so. If you do one trip from school drop-off to supermarket to office you’ll use far less fuel than if you do all those trips individually.
