Top Alternator Replacement related questions

One of the easiest ways to detect a faulty alternator is through the indicator light (the code varies according to different vehicles). If it turns on, get it checked by a trusted electrician right away. Some indications also include sudden weird noises or a burning smell coming from the engine, and irregular operation of other electrical components.

Some manufacturers suggest a total alternator replacement after 100,000 to 150,000 miles. If you detect any irregularities with your electrical system, your tasker can also help you test the alternator and have it replaced once it's broken or no longer usable.

The entire replacement process usually takes about two hours, but it may take longer if it's more rooted in the engine, or if there are more electrical and belt issues that must be resolved as well.

Airtasker is the best place to find an alternator replacement specialist near you. All you have to do is post a task with your specific needs, along with your ideal alternator replacement cost, and you'll instantly hear back from our expert auto technicians who are available to lend a helping hand whenever and wherever!

Suggested reads about Alternator Replacement

What does an alternator replacement service include?

The function of the alternator is simple: supply power to the battery and keep the electronics running. Otherwise, your vehicle will stop working. Your car will send a series of signals that will indicate a failing alternator, including a whirring noise coming from your engine and the smell of burning rubber. If you're starting to notice these warning signs, then you may need to get your alternator replaced immediately. 


Mobile Alternator Replacement
At Airtasker, you can find trusted alternator specialists and other mobile mechanics near you, offering you a convenient way of repairing your car's alternator or replacing it as needed. You don't have to risk fixing it yourself or stress over finding a car repair shop in your neighbourhood. Your mobile alternator replacement specialist will go where you are and replace your car's alternator in no time.

Disconnecting the Battery

Before the actual replacement, your Tasker will first disconnect your car battery for safety purposes. Skipping this step might trigger a live wire as they're removing or replacing the alternator, and can cause further damage as well. They will only remove the negative cable while the positive one remains attached.


Removing the old alternator
Most alternators are usually found on top of the engine. Some alternators, however, are positioned deeper in the engine and removal might take a little longer. After locating the faulty alternator, your Tasker will detach the serpentine belt or v-belt, as well as the bolts, wirings, and cables connected to the engine. After which, the old alternator will be safely removed.

Inspecting the new alternator
Your new alternator must have the same mounting holes and wire connectors as the old one. If you're hesitant or worried about buying the wrong alternator, you can always arrange for your Tasker to help you find the right one for your vehicle.

Positioning and Installing the Alternator
Your specialist will install the new alternator where the old one was placed. This process is simple—match the bolt holes, then put the battery, serpentine belt, cables, and wirings back to where they were previously. Your Tasker will then turn on your engine to check if the replacement alternator is working correctly. You can also request for a quick test drive to make sure that the process was successful.

South Brisbane QLD 4101, Australia

4th Jan 2025

Services of a qualified auto electrical professional or mechanic, required for installation of a new Alternator on my 2012 Great Wall x200 tdi, (I have the part) to be carried out at my home in a shaded covered area or I can come to a place of business. The placement of the part to be replaced is mounted on the front bottom of the engine. (Driver's side), ownership of hoist(if on business premises) , large trolley jack and or vehicle jack stands/stilts and all tools associated with type of task would be advantageous, as access is located in behind the front wheel well & could be limited from topside unless prepared to put time into teardown and reassembly to gain access.

Cristina and Sam did an excellent job, diagnosed, removed and fitted the part, and as tough as the job was they got it done with no fuss. Absolutely happy with the outcome. Cheers guys
