zuverlass 2.4 Timing Chain Kit with Water Pump for GM 2.4L Ecotec — Complete Set with Tensioner & Guides

The zuverlass 2.4 timing chain kit with water pump is a full replacement set engineered to restore timing drive reliability on compatible 2.4L and 2.2L Ecotec engines.

This comprehensive kit bundles the essential timing chains, sprockets, tensioner, guide rails and matching water pump so you can replace wear-prone components together. It’s specified to fit a range of GM vehicles — including Chevrolet Equinox, Malibu, Impala, Captiva Sport; GMC Terrain; and Buick Regal, Lacrosse and Verano — across model years listed by the manufacturer. Before ordering, confirm your engine displacement, year and OE numbers to ensure exact match.

Which vehicles and engines will this timing kit fit?

The kit is designed for GM Ecotec 2.4L and select 2.2L engines across multiple models and years. It covers many 2011–2017 2.4L applications and earlier 2.2L models where noted, but compatibility depends on specific engine codes and OE parts numbers.

• 2.4L fits: Chevy Equinox (2011–2017), Malibu (2013–2014), Impala (2014), Captiva Sport (2012–2015)
• GMC/Buick fits: Terrain (2011–2017), Lacrosse (2011–2016), Regal (2012–2017), Verano (2012–2017)
• 2.2L fits: Chevrolet Cobalt and HHR (2009–2011) and Pontiac G5 (2009)
• Always verify OE numbers like 12621505 and 94201S against your vehicle sticker or dealer documentation

What parts are included and what part numbers are supported?

This kit provides the key timing components plus a matched water pump so you replace interacting parts at once, reducing rework and misalignment risks. The product references many OEM and aftermarket numbers for cross-checking.

• Included: timing chain(s), two matching sprockets, tensioner, guide rails, hardware and water pump
• Common referenced numbers: 9-4201S, 12621505, 90537632, 12630084 and associated guide/tensioner numbers
• Note: kit may include identical sprockets for DOHC setups — confirm application before install
• Manufacturer advises checking timing marks and calibration after assembly

How does installation benefit from using a full kit with water pump?

Replacing the water pump and timing components together lowers the chance of early failures and saves labor compared with separate jobs. New rails and tensioner ensure proper chain tension and alignment, while the water pump replacement prevents coolant-leak-related damage to freshly serviced timing parts.

• Replaces wear items simultaneously to avoid repeat labor
• New tensioner and guides restore correct chain tension and reduce noise
• Matched water pump prevents coolant leaks that could compromise the timing area
• High-precision forged components aim to simplify fitment and alignment

What should I check before I buy and during installation?

Confirm vehicle year, engine displacement and OE numbers to prevent ordering the wrong kit. During installation, carefully follow timing mark alignment procedures and torque specifications; incorrect timing can cause poor running or engine damage.

• Verify fitment with OE numbers listed in the product description
• Inspect crank and cam timing marks at installation and after initial start-up
• Replace seals and gaskets as needed and use correct coolant when installing the new pump
• Consider professional installation if you’re not experienced with DOHC timing procedures

Who is this for: This zuverlass kit is intended for technicians, independent mechanics and DIYers maintaining or restoring GM vehicles that use Ecotec 2.4L and compatible 2.2L engines. It’s best for anyone who wants a coordinated set of timing components plus a new water pump to minimize future service and ensure matching replacement parts — as long as you verify the OE compatibility with your specific vehicle first.
