Replace The Spark Plugs & Ignition Coils on a Chevrolet Trax
Replacing spark plugs on the 2019 1.4L Turbo Ecotec engine (aka. LUV/LUJ) in the Chevy Trax, Sonic, Cruze, and Buick Encore is very easy. Interestingly the coil pack is a single unit - so good luck if you need one coil, you're buying all 4!
Remove The Ignition Coil Pack
Remove the engine cover. It pulls straight up with no fasteners holding it on.
Use a T-30 Torx bit to remove the 2 screws that hold the coil pack in place.
Remove the main connector from the coil pack.
The connector uses a purple sliding lock tab. Slide that back, away from the coil pack. Then you can squeeze the tab where the 3 grip lines are and wiggle the connector off.
Pull the coil straight up to remove it. You may have to wiggle it a bit to free it from the spark plugs.
To remove a spark plug, use a 5/8" spark plug socket.
The spark plug holes are rather shallow on this engine. The socket I used was long enough to not require any extensions.
