The Silverado Code (Guide)

Almost every big Silverado bill started as a small, cheap warning: a tick on a cold morning, a light shudder at highway speed, a check engine light somebody cleared and forgot.

The Silverado Code is a 53-page guide, written by a mechanic, that teaches you to catch the $4,000 problems while they're still cheap fixes, and to walk into any shop knowing what to ask for.

INSIDE (7 parts)

1. Know your truck: the four generations, find your engine and transmission in 5 minutes, check recalls for free

2. The engine: AFM and DFM lifters, the cold-start listen test, the 6.2L recall, the right oil for your engine

3. Transmission & 4WD: the 8-speed shudder and its known fix, the fluid schedule, Tow/Haul, the "Service 4WD" message

4. Lights & codes: what each light means, read the code in 30 seconds, the common Silverado codes

5. Rust, brakes & body: the 20-minute undercarriage check, where these trucks rust, two recalls on 2014 to 2018 trucks

6. Driveway maintenance: GM's schedule, the forgotten fluids, the tool kit, the monthly 10-minute check

7. The shop counter: reported price ranges, the questions to ask, how to read a quote

Every warning ends in one of three verdicts: Keep an eye on it, Book it this week, or Stop driving.
