2005 Chevrolet Avalanche 2500 Service and Repair Manual

This factory service and repair manual for the 2005 Chevrolet Avalanche 2500 covers two trims, LS and LT, on the four-door crew cab pickup, both powered by the 8.1-liter overhead-valve V8 of 496 cubic inches, naturally aspirated and gasoline-fueled. Since the two share engine, transmission and chassis, what separates them is equipment, and the manual reflects that: one mechanical specification set, and electrical and interior sections to be read according to what the truck was actually built with.

Engines covered

Known issues on the 2005 Avalanche 2500. Three recalls sit on the federal record. Under certain starting conditions the shift lever position indicator can misrepresent the gear the transmission is actually in, and the truck can then move in an unintended direction. The hydraulic brake booster's pressure accumulator can crack and separate from the assembly during ordinary operation. And the second-row center belt can be hard to route low across the hips, so the lap belt rides onto the abdomen instead. The 206 complaints lean electrical at 68, power train at 24 and air bags at 22.
