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.

my car won't start I think it might be the starter, battery, and/or alternator. it's a 2007 Infinity M35 sport. I was told the starter is in between a pulley and in a very tight spot. I don't have the parts and I was told the parts are cheaper at m&m by mt. vernon. I'm homeless parked in front of the driveway of a home I just got evicted from. can't move my car at all and I already had code enforcement tell me to move it at least to the curb. I am not sure if to keep or sell my car. I'm past my registration. And maybe if anyone is selling a legitimate car, please let me know that as well. dayum. I thank u very much for ur help and any help offered to us may god bless u all. oh and if I can I'll try paying for the parts but again I'm homeless and low on funds and enough to feed my family. if possible we can arrange some kind of deal(clean) if $ is the issue. if there's a will there's a way right? $120 for labor and I may possibly get the parts or pay u for it I don't know we can talk about it after more info: so I also need to register my car and was told that it needs a smog any one who can help? and my tires are also loosing air. just my luck
