2019 Chevrolet Blazer Service and Repair Manual

This factory service and repair manual for the 2019 Chevrolet Blazer covers a four-door sport utility offered five ways — Base, L, Premier, RS and True North — with a choice of two naturally aspirated gasoline engines: a 2.5-liter inline-four of 153 cubic inches and a 3.6-liter V6 of 222 cubic inches, both twin-cam. The engines share a service approach but not their specifications, so timing, fueling, cooling and emissions data are given separately, while the transmission, brake, steering and body wiring sections apply to every car.

Known issues on the 2019 Blazer. Two recalls are on the federal record. One covers tires cured too long in manufacture, which can break in the sidewall and lose air suddenly, or separate at a belt edge and shed tread — either way the driver can lose control. The other concerns missing bolts on the start-stop accumulator endcap, which lets transmission oil escape and can end in a loss of drive. Complaints number 186, with the power train at 55, the electrical system at 36 and steering at 27.
