What is the bolt size for a 97 Chevy cavalier starter?

There's no single "bolt size" for a 1997 Chevy Cavalier starter. The starter uses multiple bolts, and the size(s) can vary slightly depending on the specific engine (2.2L or 2.4L) and even minor variations within the model year.

To find the correct bolt size, you'll need to:

1. Consult a repair manual: A Haynes or Chilton manual specific to your 1997 Chevy Cavalier will provide the exact bolt sizes and torque specifications. This is the most reliable method.

2. Check the existing bolts: If you can access the starter bolts (even if you're not replacing the starter yet), measure them with a caliper or bolt gauge. This will give you the precise dimensions.

3. Use a parts store's online catalog: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to enter your vehicle's information (year, make, model, engine) and see diagrams and specifications of the starter and its associated fasteners.

Trying to guess the bolt size could lead to problems, so using one of the methods above is strongly recommended.
