Complete Timing Chain Repair Kit for Hyundai 24420-03000

Product Introduction

The 24420-03000 Timing Chain Kit is designed for selected Hyundai and Kia vehicles equipped with the 1.2L/1.25L G4LA Kappa petrol engine. It helps maintain accurate synchronization between the crankshaft and camshaft, supporting stable valve timing, smooth power delivery and reliable engine operation.

Manufactured with heat-treated steel timing components and wear-resistant guide materials, the kit is suitable for engine repair, timing-system overhaul and preventive replacement. Kingmay supplies factory-direct wholesale pricing, flexible MOQ, mixed-SKU ordering and customized packaging.

Important: OE 24420-03000 / 2442003000 specifically identifies the timing-chain tensioner arm/guide in the original Hyundai/Kia catalogue. When sold as a “Timing Chain Kit,” it is normally used as one of several OE reference numbers for the complete aftermarket kit.

Product Overview

A timing chain system connects the crankshaft and camshaft so that the engine valves open and close at the correct moment. After extended operation, the chain, tensioner and guide rails can wear, causing excessive clearance and inaccurate valve timing.

Replacing the related timing components together helps restore correct chain tension and reduce the risk of repeated disassembly. Depending on the selected configuration, the complete kit may contain the chain, hydraulic tensioner, guide rails, gears, crankshaft sprocket and oil seal.

Core Specifications

The 160-link, 6.35 mm pitch specifications are documented for aftermarket kits cross-referencing the relevant Hyundai/Kia OE numbers. Actual kit contents can be offered in 7-, 9- or 10-piece configurations, so the components should be confirmed against the product photograph or quotation before ordering. 

Typical Kit Contents

A full configuration may include:

• 1 × timing chain

• 1 × timing-chain tensioner

• Up to 4 × timing-chain guide rails

• 2 × timing gears

• 1 × crankshaft sprocket

• 1 × oil seal

Kit contents differ between suppliers and between CVVT and non-CVVT engines. The listed components should therefore be treated as a common full-kit configuration, not a guaranteed packing list. 

Compatible Vehicles and Years

Fitment varies according to market, production date and CVVT configuration. Always confirm the VIN, engine code and original part numbers before ordering.

Main Functions

• Maintains synchronization between the crankshaft and camshaft.

• Controls the correct opening and closing sequence of the engine valves.

• Keeps the timing chain at the required operating tension.

• Prevents excessive chain movement, vibration and contact with surrounding components.

• Helps the engine maintain stable combustion and consistent power delivery.

• Reduces timing-system noise when replacing worn chains, guides and tensioners.

• Protects the cylinder head, valves and pistons from damage caused by severe timing errors.

Product Features

• Engine-specific fit: Designed around the dimensions and mounting points used by the G4LA timing system.

• Wear-resistant construction: Heat-treated steel chain components help withstand repeated high-speed operation.

• Stable chain guidance: Reinforced guide surfaces support smooth chain movement and help reduce vibration.

• Coordinated replacement: Replacing related components together reduces the possibility that an old tensioner or guide will shorten the service life of a new chain.

• Low-noise operation: Correct chain tension helps minimize rattling and impact noise during cold starts.

• Ready for wholesale supply: Available with flexible quantities, mixed batches and private-label packaging.

• Professional quality control: Components are inspected for appearance, dimensions, assembly condition and packaging before shipment.

Symptoms of a Worn Timing Chain System

The timing chain kit should be inspected if the vehicle develops any of the following symptoms:

• Metallic rattling during a cold start

• Continuous noise from the timing-cover area

• Rough idle or unstable engine speed

• Reduced acceleration or abnormal power loss

• Difficult starting

• Increased fuel consumption

• Check-engine warning light

• Camshaft/crankshaft correlation fault codes

• Plastic or metal debris found in the engine oil

• Engine misfire caused by incorrect valve timing

Ignoring these symptoms can allow the chain to jump one or more teeth. In severe cases, the pistons and valves may contact each other, resulting in expensive internal engine damage.

Common Problems and Solutions

Installation and Usage Tips

• Confirm the VIN, engine code and original OE numbers before dismantling the engine.

• Compare every new component with the removed part before installation.

• Disconnect the battery and set the engine to top dead center before removing the old timing system.

• Do not rotate the crankshaft and camshaft independently after the chain has been removed.

• Align all crankshaft, camshaft and chain timing marks precisely.

• Inspect the camshaft gears, crankshaft sprocket, oil pump and timing cover before assembly.

• Replace damaged seals and gaskets instead of reusing them.

• Clean the mating surfaces and prevent sealant from entering the engine oil passages.

• Lubricate the chain and guide contact surfaces with clean engine oil during assembly.

• Tighten all bolts according to the vehicle manufacturer’s torque specifications.

• Rotate the engine manually through at least two complete crankshaft revolutions before starting.

• Change the engine oil and filter if sludge or metal debris is found.

• After installation, allow the engine to idle and check for unusual noise, warning lights and oil leaks.

Professional installation is strongly recommended because incorrect valve timing can cause serious engine damage.

Maintenance Recommendations

A timing chain does not normally have a fixed replacement interval like a timing belt, but its service life depends heavily on lubrication quality and maintenance history.

For longer timing-system life:

• Use the engine-oil viscosity and specification recommended by the vehicle manufacturer.

• Replace the oil and oil filter on schedule.

• Avoid operating the vehicle with low oil pressure or insufficient oil.

• Investigate cold-start rattling instead of waiting for it to become continuous.

• Keep the engine lubrication passages free of sludge.

• Inspect the entire timing system during cylinder-head or engine-overhaul work.

• Replace the chain, tensioner and guides as a coordinated set when significant wear is found.
