Changan CS35 Intake Phaser – VVT, Euro 4, Part No.: H15006-0300

Let’s keep it simple—this isn’t just a “metal part” on your Changan CS35’s engine. It’s the key control component for the engine’s Variable Valve Timing (VVT) system (specifically for intake valves), built to meet Euro 4 emission standards: a durable, precision-machined part made of high-strength aluminum alloy (to handle high engine temperatures) with an integrated oil pressure chamber and control mechanism. Mounted on the end of the CS35’s intake camshaft (inside the timing cover), it works with the engine control unit (ECU) to adjust when the intake valves open and close. Think of it as the “engine’s ‘intake timer’”: without it, the intake valves can’t adapt to driving needs—leading to weak acceleration, higher fuel use, and failure to meet Euro 4 emission rules.

This intake phaser is exclusive to Changan CS35 (Euro 4 models)—always check your vehicle’s VIN and emission standard to confirm fitment! It’s tailored to the CS35’s specs: its timing adjustment range matches the CS35 engine’s airflow demand (works for idle, acceleration, and high speed), its oil pressure response aligns with the ECU’s signals (no lag), and its design meets Euro 4’s strict emission limits (cuts harmful gases like NOx). Grab a generic phaser or one for non-Euro 4 models? You’ll run into trouble: wrong timing range (ruins engine power), poor oil pressure control (causes valve noise), or failure to pass emission tests.

 Core Jobs: Optimize Intake Timing, Save Fuel & Meet Euro 4 Standards

As the heart of the CS35’s VVT system for intake valves, it does three key jobs to balance performance, efficiency, and 环保 (environmental compliance):

Adjust intake valve timing dynamically: When you drive the CS35—whether idling at a stoplight, accelerating to overtake, or cruising at high speed—the ECU sends signals to this phaser. It uses engine oil pressure to rotate the intake camshaft slightly, changing when the intake valves open and close. For example: at low speeds, it opens valves later (reduces fuel waste); at high speeds, it opens valves earlier (lets more air into the engine for stronger power).

Cut fuel use & reduce emissions: By matching intake timing to driving conditions, the engine burns fuel more completely. This lowers fuel consumption by 3–5% (vs. a fixed-timing system) and reduces harmful emissions—critical for meeting Euro 4 standards (limits on pollutants like carbon monoxide and particulate matter).

Smooth engine operation: It stabilizes the CS35’s idle (reduces engine shaking) and eliminates “flat spots” during acceleration (no sudden power drops). This makes driving smoother and reduces wear on engine parts like pistons and valves.

This H15006-0300 intake phaser only fits Changan CS35 Euro 4 emission models—wrong fit means performance and emission issues:

Fits These: All Changan CS35 variants with Euro 4 certification (matches the engine’s VVT system, ECU protocol, and intake camshaft specs—confirm VIN and emission label).

Won’t Fit These:

Changan CS35 non-Euro 4 models: Older CS35 with lower emission standards (e.g., Euro 3) have different VVT tuning (phaser causes timing errors).

Other Changan models: Like CS75, UNI-T, or Eado—different engine sizes, camshaft designs, and ECU signals (can’t install or function).

Non-Changan vehicles: Even if similar in look, engine VVT systems and oil pressure specs differ (no functional match).

Modified CS35 engines: Aftermarket turbo kits or camshaft upgrades change airflow demand—original phaser can’t adapt (leads to poor performance).

Installation & Upkeep (Pros Only—Engine Safety Is Critical!)

Installation: Must Be Done by Certified Technicians

Replacing this intake phaser requires precise timing alignment—DIY risks destroying the CS35’s engine:

Prep: Techs drain engine oil (to avoid spills), remove the timing cover (to access the camshaft), and disconnect the phaser’s oil line and electrical connector (linked to the ECU).

Remove old phaser: They unbolt the old unit from the intake camshaft, clean the camshaft end (wipe off oil sludge), and check for wear on the camshaft teeth (damaged teeth need repair).

Install new phaser: They align H15006-0300’s timing marks with the camshaft and timing cover, bolt it to Changan’s exact torque specs (too tight cracks the aluminum body), then reconnect the oil line and ECU connector.

Test: They refill with Changan-approved oil, start the engine, and use a diagnostic tool to check VVT timing (ensures it matches ECU commands). They also test drive to confirm smooth acceleration, no valve noise, and no emission warning lights.

Maintenance: Easy Checks to Avoid Failure

Use high-quality engine oil: The phaser relies on clean, viscosity-matched oil (follow Changan’s recommendation—e.g., 5W-30). Dirty or wrong oil clogs the control valve (causes timing errors).

Change oil & filter regularly: Follow the CS35’s maintenance schedule (every 5,000–7,500 km). Old oil degrades and loses pressure control—ruining the phaser over time.

Watch for warning signs: If the CS35’s VVT warning light comes on, or you hear a “rattling” from the timing cover (valve noise), stop driving and check the phaser—delays cause engine damage or failed emission tests.

Inspect during major service: Every 100,000 km, have techs check the phaser’s oil pressure response (via diagnostic tool) and look for oil leaks—early fixes save costly repairs.

Summary: Changan CS35 Intake Phaser (VVT, Euro 4, H15006-0300)

This is an exclusive intake phaser for Changan CS35 Euro 4 emission models (confirm VIN and emission label for fitment). Made of high-strength aluminum alloy, it integrates an oil pressure chamber and control valve (OCP), mounted on the CS35’s intake camshaft end (inside the timing cover) to work with the ECU as the core of the engine’s VVT system.

Its core functions: Dynamically adjust intake valve timing (open later at low speeds to reduce fuel waste, earlier at high speeds for stronger power); cut fuel consumption by 3–5% and lower emissions to meet Euro 4 standards (limits pollutants like CO and NOx); stabilize idle and eliminate acceleration "flat spots" for smoother operation and reduced engine wear.

It only fits all Changan CS35 Euro 4 variants. It is incompatible with CS35 non-Euro 4 models (e.g., Euro 3), other Changan models (e.g., CS75, UNI-T), non-Changan vehicles, and modified CS35 engines. Installation requires certified techs: drain oil, remove timing cover, align timing marks, bolt to specs, and test with a diagnostic tool. Maintenance includes using Changan-recommended oil (e.g., 5W-30), changing oil/filter every 5,000–7,500 km, monitoring warning signs (VVT light, timing cover rattling), and inspecting at 100,000 km. Original parts ensure precise timing, ECU compatibility, and durability—aftermarket options risk warping, poor performance, or emission non-compliance.
