Complete 2.4L Ecotec timing chain kit with VVT sprocket and all internal guides and tensioners required to replace worn timing components on compatible 2.2L and 2.4L GM engines.

If your Chevy, GMC, Buick or Pontiac with a 2.2L/2.4L Ecotec engine needs a full timing component refresh, this GDO kit supplies the chain, VVT sprockets, crank sprocket, guides, tensioner and oiling gear in one package. It’s engineered to match factory fitment numbers and covers many model years across Equinox, Terrain, Malibu, Verano, Regal, Lacrosse and other compatible vehicles. The kit carries multiple reference numbers so it’s easier to verify fitment against OEM part lists.

Which vehicles and model years does this kit cover?

This kit fits a broad range of GM mid‑size cars and crossovers using the 2.2L or 2.4L Ecotec engines. Coverage includes many model years, but you should confirm against your VIN or the listed reference numbers before purchasing.

• 2011–2017 Chevy Equinox (2.4L)
• 2011–2017 GMC Terrain (2.4L)
• 2012–2017 Buick Verano, Regal, Lacrosse (2.4L)
• Select Chevy Malibu, Captiva Sport, Orlando, Impala, HHR, Cobalt and Pontiac G5 model years (2.2L/2.4L)

What components are included and why they matter?

The kit bundles the primary timing chain and both VVT and crank sprockets plus the tensioner and multiple guide/damper arms. Replacing all interacting parts at once prevents uneven wear, simplifies installation, and reduces the chance of future timing problems that can damage the engine.

• Center timing chain and crank sprocket for accurate tooth engagement
• 2x VVT sprockets (exhaust/right) to maintain variable valve timing control
• Tensioner and right upper tensioner arm to keep chain tension stable
• Left, upper and right guide/damper arms plus a timing gear oiler for proper chain routing and lubrication

How should this kit be installed and what should a buyer expect?

Installation is recommended for trained technicians or experienced DIYers with proper tools and repair manual access. The kit replaces internal timing hardware, so expect partial disassembly of front engine components and careful timing alignment procedures to avoid engine damage.

• Professional installation recommended; follow factory service procedures
• Confirm exact fitment using vehicle year/make/model or OEM reference numbers
• Allow time for front cover removal, timing alignment and oil system checks

Which reference numbers match this GDO timing chain kit?

The kit is cross-referenced to many OEM and aftermarket numbers to help you verify compatibility with parts catalogs and fitment tools. Use these references when comparing parts or ordering through vehicle‑specific filters.

• Common references include 9-4201SAVVT1, 12588387 and 12621505 among others
• Refer to the included listing image for the full range of cross‑reference numbers
• Check your vehicle’s parts lookup or VIN to confirm exact match
