How much would a starter for a 1997 Chevy Blazer

If you are replacing it yourself, the factory starter is $167. The range for aftermarket starters is between $90 and $170, plus the core charge. If you are going to have a shop do it, they have no right to charge more than one hour labor for this. Starter replacement is one of the easiest of the repairs. You disconnect your battery, detach the cable on the starter, remove the bolts holding it in and pull it out. The new one goes in in the reverse order.

i hope this helps
