What is the oil plug bolt size on a Chevy 2002 s10?

The oil drain plug size on a 2002 Chevy S10 depends on the engine. There are a few different engines that could have been in that model year. You must check your vehicle's specific engine to be sure.

To find the correct size:

1. Locate your engine: Check your vehicle's identification information (usually found on the driver's side dashboard or doorjamb) to determine the exact engine (e.g., 2.2L, 4.3L).

2. Consult a repair manual: A repair manual specific to your year and engine will definitively state the oil drain plug size. You can find these online (e.g., Haynes, Chilton) or at auto parts stores.

3. Look it up online: Some websites allow you to search by year, make, model, and engine to find this information, but always double-check with a reputable source.

Don't guess! Using the wrong size bolt can strip the threads and cause significant damage. Take the time to confirm the correct size before attempting an oil change.
