What are the 2001 chevy silverado ground wire locations?

There are over thirty ground wires on the 2001 Chevrolet Silverado, many of which You'll never need to fuss with. If You suspect that You have a failed ground wire, the best course of action is to look for a broken or shorted cable in the engine bay, either from the top of the truck or the bottom. However, the ones You'll likely be most interested in are the engine grounds. The engine grounds can be found, predictably, on the engine block. These go to the firewall, the core support, and the sub frame. Most commonly, You'll find a damaged wire due to age (on a two-decade-plus year old truck), but corrosion is another major inhibitor. If replacing, make sure You clean the area well with an anti-corrosion agent to maximize efficacy.
