Titus Livius: Men are only clever at shifting blame from their own shoulders to those of others. Peter McWilliams: Stubbornness is also determination. It's simply a matter of shifting from won't power to will power.
The alternator replacement cost can be quite high, with prices running between $133 and $915 for a new alternator. The work itself is quite straightforward, so the cost for labor is normally quite low in comparison to other automotive services. The alternator cost will range from $200 to $700 just for the part itself! To have a new alternator fitted at a garage you can expect to pay between $172 to $1046 with an average cost in the mid $500 range, depending on the part used and the model of car you own.
Because this is the easier of the two, we'll go into it first. The cost of a new alternator varies by vehicle make. Average is about $100 or so for 4 cylinder engines and $150 for 6 or 8 cylinders. Most mechanics can install a new alternator in about half an hour and most home DIY mechanics can do it themselves. A rebuilt alternator can be purchased for about half the price of new, but may not have the same warranty as a new unit. The cost savings often makes it worth the risk, however, and most will function as if new.
