Cylinder 2 sits on the passenger side, the right-hand bank when you’re facing the front of the engine, and it is the second cylinder from the front on that bank.
GM’s Gen III/IV LS family uses two banks of four cylinders. Bank 1 is the passenger side (cylinders 1–4) and Bank 2 is the driver’s side (cylinders 5–8). When you look at the engine from the front, the front-most cylinders are 1 (bank 1) and 5 (bank 2), with 2 behind 1, 6 behind 5, and so forth. Cylinder numbers run in order from front to rear along each bank.
Locating cylinder 2 in the engine bay
To visually locate cylinder 2 on the 5.3L LS, use these steps:
- Identify the front of the engine by the timing cover/harmonic balancer.
- Stand in front of the engine and locate the passenger side bank (the right-hand side when facing the car’s grille).
- Count cylinders on that bank from the front of the engine: 1 is at the front, 2 is directly behind it, followed by 3 and 4 toward the rear.
- Follow the spark plug boot or coil pack to cylinder 2 to confirm its location.
Understanding this layout helps when replacing spark plugs, coils, or diagnosing misfires on the 5.3L LS engine.
Firing order reference
The LS family commonly uses the firing order 1-8-7-2-6-5-4-3. Cylinder 2 is the second cylinder in Bank 1's sequence, which helps when checking timing or diagnosing ignition timing issues.
Summary
For a 5.3L LS V8, cylinder 2 is on the passenger-side (right) bank, and it is the second cylinder from the front on that bank. This convention holds across LS engines, though always verify with your vehicle’s service manual, as some applications or special editions can vary in physical orientation.

The introduction of distributorless ignition systems in Chevy's LS series engines brought a significant change: a 1-8-7-2-6-5-4-3 firing order. The swap of cylinders 4 and 7, along with 2 and 3, reduces internal harmonics, improving high-RPM performance and durability.
