What size wrench is needed for 1997 Chevrolet S10 beeder valve clutch?

There's no single wrench size that universally fits the bleeder valve on a 1997 Chevrolet S10 clutch. The size depends on the specific model and even the year within that model year. They commonly use either an 8mm or a 10mm wrench.

To find the correct size:

1. Locate the bleeder valve: It's usually a small valve on the top of the clutch slave cylinder. This cylinder is located near the transmission bell housing. You'll likely need to consult a repair manual or a diagram for the exact location.

2. Inspect the bleeder valve: Once you find it, carefully look at the size of the hex head on the valve. Use a wrench that *fits snugly* without forcing it.

It's best to have both an 8mm and a 10mm wrench on hand to be sure you have the right one. Trying to force the wrong size can easily damage the bleeder valve.
