GMC SIERRA 1500 2014 - 2019 - DIY Repair & Maintenance Manual (Paperback) (ISBN-13: 9798188418748)

Stop swapping parts and hoping. This systematic DIY handbook takes you through the 2014-2019 Sierra 1500 the way a real job unfolds - from correctly identifying the exact truck in front of you to reasoning from a symptom to its true cause. Written for the committed owner, the weekend mechanic, and the working technician, it explains how each system works, how to service it correctly, and how to diagnose it in a logical order that saves you time and money.

Built specifically around the K2XX-platform trucks (2014-2018 and the 2019 Sierra 1500 Limited), with a dedicated chapter on the all-new 2019 T1XX Sierra 1500 so you never confuse the two and order the wrong parts.

Inside this 14-chapter manual you'll learn how to:

• Decode the 17-character VIN (with the check-digit calculation) and read SPID/RPO codes to confirm engine, transmission, and axle before you touch a bolt


• Service and diagnose the EcoTec3 engine family - the 4.3L V6 and the 5.3L and 6.2L V8s - including direct injection, variable valve timing, and cylinder deactivation


• Tackle the generation's known weak points: the V8 lifter failure, direct-injection intake-valve carbon, and fuel-pump and blend-door actuator issues


• Service and diagnose the 6L80, 6L90, and 8L90 automatic transmissions, transfer case, driveline, and axles


• Work through fuel, air, and emissions; ignition and engine controls; cooling and lubrication


• Repair and diagnose suspension, steering, alignment, brakes, ABS, and stability control


• Master the electrical, charging, starting, and body-electrical systems and the data network behind them


• Read trouble codes, freeze-frame, and scan data, and apply one repeatable diagnostic method to any fault


• Reach the numbers fast with appendices for torque specifications, fluid capacities, and diagnostic trouble codes With learning objectives, worked procedures, practice problems and answer keys, chapter summaries, and a full glossary and index, this is a reference you can trust in the driveway or the shop.
