2018 Chevrolet Sonic Service and Repair Manual
Regular price
$49.99 USD
Unit price
This factory service and repair manual for the 2018 Chevrolet Sonic works with two engines rather than three: the turbocharged 1.4L DOHC inline-four of 83 cubic inches and the naturally aspirated 1.8L of 110 cubic inches that runs flex fuel or gasoline. Both go into a four-door hatchback or a four-door sedan sold as LS, LT and Premier. With one less displacement to account for, the fuel, ignition and emissions procedures fork only once, while the chassis and body electrical material covers the whole range at once.
