The Chevrolet 2.0L turbo firing order is 1-3-4-2. GM Powertrain’s specification sheet for the 2.0L LTG lists that order for the engine, which it describes as a 1,998 cc inline-four with direct injection and a twin-scroll turbocharger.
That sheet, published by GM in 2016, rates the LTG at 275 hp at 5,600 rpm and 295 lb-ft as tested in the Chevrolet Camaro, and notes that output varies with the application.
Chevrolet 2.0L turbo firing order
The firing order is 1-3-4-2. Each cylinder has its own coil, so you will not route plug wires. The order is useful when you read a misfire code, swap coils to see whether a misfire follows the coil, or check plugs one at a time.
If you have a different Chevy engine, check the guide for that engine. For V6 and V8 engines the order is different. The Chevrolet 5.3L and Chevrolet 3.6L guides cover those.
Chevrolet 2.0L turbo cylinder numbers
The cylinders sit in a straight line and are numbered 1 to 4 from one end of the engine to the other. GM’s sheet notes that the LTG is built to mount either lengthwise, as in the rear-wheel-drive Camaro and Cadillac ATS, or sideways, as in the front-wheel-drive Malibu and Equinox.
Because the mounting changes which way the engine faces, confirm where cylinder 1 is in the service information for your car, or from the cylinder markings on the engine, before you count coils.
Chevrolet 2.0L turbo vehicle applications
GM used the 2.0L turbo LTG in several Chevrolet, Buick and Cadillac models, including:
- Chevrolet Camaro
- Chevrolet Malibu
- Chevrolet Equinox
- Buick Regal
- Cadillac ATS and CT6
The RPO Archive entries for LTG list factory documentation for the Chevrolet Camaro, Malibu and Equinox, the 2018 and 2019 Buick Regal and the Cadillac ATS and CT6. If your car has a different 2.0L turbo engine code, check the order for that engine.
Our take
On the 2.0L turbo, the order is 1-3-4-2. Work out which way the engine is mounted in your car and confirm where cylinder 1 is first, then count the coils from that end.
