First, let’s break it down simply—this isn’t just a random engine part. It’s the “timing controller” for your CS35’s intake valves, part of the Variable Valve Timing (VVT) system, and it’s built specifically to meet Euro 5 emission standards. You’ll find it mounted on the engine’s intake camshaft (the part that controls when intake valves open/close).
Here’s what it actually does: Your engine needs different valve timing at different speeds—for example, slow speeds (like city driving) need valves that open/close gently to save fuel, while high speeds (like highway acceleration) need valves that open wider and longer for more power. This intake phaser uses oil pressure to tweak the intake camshaft’s rotation slightly, adjusting when the intake valves open/close. Without it, your CS35 would burn more gas, have less power, and fail to meet Euro 5’s strict pollution rules (it cuts harmful emissions like NOx and unburned fuel).
This phaser is
made only for Changan CS35 models that meet Euro 5 standards—always check your vehicle’s emission rating and VIN to be sure! It’s designed to fit perfectly: its gear matches the CS35’s camshaft teeth (no slipping), its oil inlet lines up with the engine’s oil passages (no pressure loss), and its internal components are calibrated to the CS35’s engine specs (not too fast, not too slow). Grab a generic one? You’ll run into issues: it won’t adjust timing
right (engine feels sluggish), leaks oil (ruins
engine parts), or can’t meet Euro 5 emissions (you might fail inspections).
It’s all about efficiency, power, and clean emissions—here are 3 key jobs it does for your CS35:
Saves fuel at low speeds: When you’re driving slowly (e.g., stop-and-go traffic), it adjusts the intake valves to open later. This stops extra air/fuel from getting into the engine, cutting down on wasted gas.
Boosts power at high speeds: When you accelerate (e.g., merging onto the highway), it tweaks the valves to open earlier and stay open longer. This lets more air/fuel into the engine, giving you more horsepower.
Meets Euro 5 emissions: By controlling valve timing precisely, it ensures the engine burns fuel more completely. This reduces harmful pollutants (like nitrogen oxides) that Euro 5 bans—so your CS35 passes emission tests.

This H15005-0404 intake phaser only works for Changan CS35 models with Euro 5 emissions—wrong fit = engine trouble:
This part controls engine timing—DIY installation will ruin your CS35’s engine:
Engine prep: Techs drain the engine oil (to avoid spills) and remove parts like the timing cover to access the intake camshaft.
Remove old phaser: They unbolt the old phaser from the camshaft, being careful not to damage the camshaft teeth (a single chip ruins the camshaft).
Mount the new one: They align H15005-0404 with the camshaft’s keyway (a small notch for perfect alignment), bolt it down to exact torque specs (too tight = cracks; too loose = slipping), then reconnect the oil lines.
Test timing: They use a timing tool to check if the phaser adjusts correctly, refill the engine with Changan-approved oil, and test-drive the CS35—ensuring no check engine lights and smooth power.
Change oil regularly: Use only Changan-recommended oil (low-quality oil clogs the phaser’s oil passages—ruins timing control). Change oil every 5,000–7,000 km.
Check for leaks yearly: Have techs inspect the phaser’s sealing rings (oil leaks mean lost pressure—phaser stops working).
Don’t ignore the check engine light: If it turns on for VVT/timing issues, fix it fast (delays cause camshaft or valve damage)

Exclusive to Changan CS35 with Euro 5 emissions (confirm via VIN), this intake camshaft-mounted part controls the VVT system. It adjusts
intake valve timing via oil pressure—saving fuel at low speeds, boosting power at high speeds, and ensuring Euro 5 emission compliance.
It fits perfectly; generic versions misadjust timing, leak oil, or fail emissions. Maintain with Changan-approved oil (change every 5,000–7,000 km) and fix check engine lights fast. Only the original guarantees engine efficiency and legal compliance.
