Chevrolet Camaro Alpha

2.0-liter turbo four-cylinder with 252 hp and 260 lb-ft. Modern direct injection with dual VVT, paired with the 9T50 nine-speed automatic. Dropped from the Equinox after 2020 because the premium didn't make sense for family buyers. Mechanically more solid than the 1.5 turbo.

• !! LSPI Piston Ring-Land Cracking from 113,000 km

  Low-Speed Pre-Ignition causes extreme pressure spikes cracking piston ring lands. Most susceptible on pre-2016 LTG; Equinox LK9 variant benefits from Dexos1 Gen 2 oil mandate (TSB 17-NA-039) but failures still occur with wrong oil or regular fuel.

  Symptoms: Sharp metallic knock under light throttle in high gear, P0300 misfires, increasing oil consumption, blue exhaust smoke

• !! Timing Chain Tensioner Premature Wear from 145,000 km

  Weak timing chain tensioner loses hydraulic pressure under low oil or extended intervals. Plastic guides wear producing cold-start rattle. Progresses to P0011/P0014 cam codes and potential valve contact.

  Symptoms: Metallic rattle at cold start (2-3 seconds), P0011/P0014 codes, rough idle, timing-related misfires

• !! Active Thermal Management Valve & Water Pump Failure from 145,000 km

  Equinox LK9 variant uses electronically controlled coolant flow valve instead of traditional thermostat. Electric actuator and auxiliary water pump are failure points causing overheating or P0128.

  Symptoms: Overheating warning, P0128 code, heater output varies, coolant loss

3.6L V6, the most refined GM High Feature V6. Revised timing chain over the LFX, later chain stretch onset (120k+ mi with proper oil changes). GDI-only means carbon buildup on intake valves. AFM deactivates cylinders 3 and 6; lifter collapse can destroy the camshaft. AFM disabler ($200) is cheap insurance. 308 hp moves the Colorado well.

• !! AFM Lifter Collapse / Camshaft Damage (LGZ) from 110,000 km

  AFM deactivates cylinders 3 and 6 under light load. Stuck lifters grind cam lobes flat, sending metal debris through the engine within 2,000 mi. Requires head removal, lifter/tray/camshaft replacement. AFM disabler ($200) may prevent occurrence.

  Symptoms: Loud valvetrain tick at idle, misfire on cyl 3 or 6, oil consumption 1 qt/1,000 mi

6.2-liter Gen V V8 with direct injection — the LS3 evolved into modernity. 455 hp at 6,000 rpm. DI brings the characteristic cold-start tick. AFM (auto) or DFM (2019+) deactivates cylinders — same lifter risk as L99. Manual cars have AFM hardware but software-disabled, significantly fewer failures. PCV system and catch can reduce carbon deposits.

• !! AFM/DFM Lifter Collapse from 60,000 km

  Same as L99: automatics heavily affected, manuals (AFM disabled) much less. Range disabler (~$200) or AFM delete (~$2,500).

6.2-liter V8 with Eaton TVS2300 supercharger, direct injection, variable valve timing — the final evolution of the small-block architecture. 650 hp at 6,400, 650 lb-ft at 3,600. Blower pushes from 1,800 rpm, wall of torque at 3,500. Charge cooling via water/air system: perfect on street, track needs bigger coolers after lap 3. Same AFM lifter risk on automatics. The LT4 is the last factory-supercharged Camaro engine — production ended 2024, collector piece.
