Chery Tiggo 7 Pro Timing Chain (Part No.: E4G181007080)

First of all, let's briefly analyze: The timing chain E4G181007080 of the Chery G7 Pro is not merely a "metal chain" - it is the "precise timer" of your engine. It can be imagined as a solid and silent bond connecting two key components of the Tiger 7 Pro E4G18 engine: the crankshaft (driving the piston) and the camshaft (opening/closing the engine valves). What does it work? To ensure that these two parts are fully synchronized, the valve will open accurately when the piston is in the correct position without any collision. Without it, your engine will stall within seconds, lose power, and even suffer catastrophic damage (such as valve bending or piston damage).

This timing chain is specially designed for the Chery G7 Pro model equipped with the E4G18 engine (the "E4G18" in the part number confirms this) - please be sure to check your vehicle identification number or user manual for verification! Its design perfectly matches the specifications of the E4G18 engine: its length and number of teeth are consistent with those of the crankshaft/camshaft gears (without slippage or misalignment), its strength can control the engine's torque (without stretching under load), and it works in conjunction with the engine's oil system (to maintain lubrication for a long time). A universal time series chain? You will face disaster: it will stretch rapidly (causing the engine timing to fail), skip gears (causing the valve to collide with the piston), or wear out prematurely, spending thousands of dollars to repair the engine.

1. Core work: Why does this chain keep your engine running

Its role is crucial to the engine's health - it does three key things for your Tiger 7 Pro:

Synchronous valve and piston: It ensures that the camshaft opens/closes the valve precisely when the piston moves up/down. For instance, when the piston sucks in air/fuel, it keeps the intake valve open; when the piston expels exhaust gas, the exhaust valve opens - no overlap, no collision.

Efficient power transmission: It connects the rotation of the crankshaft with the camshaft, so that the "bottom" (piston) and "top" (valve) of the engine can work together. This seamless power transmission enables the engine to run smoothly without delay or misfire.

More durable than timing belts: Unlike rubber timing belts (which need to be replaced every 60k-100k kilometers), the construction of this metal chain can extend the engine's service life (if properly maintained) - without the hassle and costly belt replacement.

• Fits These Models: Chery Tiggo 7 Pro variants equipped with the E4G18 engine (confirm via VIN to match your engine code).

• Won’t Fit These:

• Tiggo 7 Pro models with other engines (e.g., 1.6T or 2.0T): Their crankshaft/camshaft specs differ—chain length/tooth count won’t match.

• Other Chery models (e.g., Tiggo 8 Pro, Arrizo 6 Pro): Their engine designs (e.g., overhead cam layout) need different timing chains—no alignment.

• Non-Chery vehicles: Even if it “looks similar,” the gear sizes and tensioner compatibility are wrong—causes instant timing failure.

 Installation & Maintenance (Pros Only—Engine Timing Is Non-Negotiable!)

Installation: Certified Chery Technicians Mandatory

1. Engine prep: Techs drain the oil, remove engine covers, and access the timing cover (careful not to damage surrounding parts).

2. Align and install: They use the timing marks to line up the chain with the crankshaft/camshaft gears, install the tensioner, and test tension (too tight = chain wear; too loose = skipping).

3. Verify and reassemble: They rotate the engine manually to confirm no valve-piston contact, refill oil, and test-run the engine (check for misfires or noise).

Maintenance: Keep It Running for the Engine’s Lifetime

• Use Chery-approved engine oil: The chain relies on clean, high-quality oil for lubrication—cheap oil causes premature wear (change oil every 5k–7k km).

• Check during major services: Techs inspect the chain’s tension and wear during 100k km+ services (look for stretching or loose tensioners).

• Listen for : If you hear a rattling noise from the engine (especially at startup), get it checked—loose chain or failing tensioner = imminent timing issues.
