How much is this gonna cost me??
The starter is the second easiest part to change on a car, outside of a battery.
2 bolts, and one wire leading to the battery.
Hardest thing to do is get to it. Usually will take no more than 15min on an easily accessible car, and around an hour if you have a pain in the ass car.
Of course there are occasions where you strip a bolt or an oddity of that sort. But overall, even a weak chickie can do it.
