Mango S 3.6L Timing Chain Kit for GM V6 — Complete Set with Tensioner & Sprocket

The Mango S 3.6 Timing Chain Kit is a complete replacement timing set—chain, guides, tensioner and sprocket—designed to restore correct valve timing on compatible 2.8L, 3.0L and 3.6L V6 engines.

This full timing chain assembly is built as a direct fit replacement for GM V6 engines used across Chevrolet, GMC, Cadillac, Buick, Pontiac and Saab models. It addresses the most common timing-related symptoms—rattles from the front of the engine, noisy chains, and timing fault codes—by replacing worn chains, guides, tensioners and related hardware to match original factory specifications.

How will this timing kit fix noisy or rattling front-end sounds?

Excessive chain slack, worn guides and a weakened tensioner often cause the characteristic rattle from the timing cover area. Replacing the entire kit renews the components that control chain tension and alignment, which reduces play and restores the correct chain path.

• Includes primary chain, guide rails, hydraulic/mechanical tensioner and replacement sprocket(s)
• Direct replacement for OEM part numbers listed, built to original spec fitment
• Restores proper tension and reduces chain slap and timing noise
• Prevents jump or timing drift that can trigger ECU fault codes

Which vehicles and engines are compatible with this Mango S kit?

This timing set is made for GM 2.8L, 3.0L and 3.6L V6 engines installed in a wide range of model years and platforms. Always verify fitment for your exact year, make and model before ordering to ensure correct application.

What parts are included and which OEM numbers does it replace?

The kit ships as a complete engine timing set so you don’t have to piece together components. It replaces a long list of factory part numbers and is intended as a direct swap to match original geometry and durability.

• Primary timing chain, chain guide rails, tensioner assembly and sprocket(s)
• Direct-replacement for OEM numbers such as 1255861, 1262514, 12559919 and many others
• Supplied as one full set to replace the factory timing components at once
• Manufactured to match factory fitment and tolerances for straightforward installation

Can I install this myself or should a shop handle it?

Replacing a timing chain kit requires engine access, torque-sequence accuracy and correct timing alignment; it is moderate-to-high complexity. Experienced DIYers with proper tools can perform the swap, but many owners choose a qualified mechanic to ensure timing and front-cover sealing are correct.

• Requires timing cover removal, alignment tools and torque specifications
• Inspect related seals, gaskets and water pump during service for best results
• Re-torque and alignment checks recommended after installation
• Follow vehicle-specific service manual or professional technician guidance

Who is this for: The Mango S 3.6 Timing Chain Kit is intended for owners and technicians working on GM 2.8L/3.0L/3.6L V6 engines who need a full, factory-fit timing replacement. It suits drivers experiencing timing-related noise or fault codes, garages that perform engine timing services, and restoration projects that require like-for-like replacement parts. Confirm fitment for your vehicle year and engine before purchase to ensure compatibility.
