1. What It Is
This tensioner’s an OE-standard part made just for Chery A13. It’s a key piece of the engine’s timing system—fits the original mounting spot, interface, and size in the A13’s engine bay perfectly. Its main job? Keep the timing belt or chain at the
right tightness, so the engine’s valves and pistons work in sync. It’s small but super important—protects the engine’s stability and lifespan, and it’s a must-have for repairs or maintenance.
2. What It Does & How It Works
Core Jobs
Keeps Tension Steady: It automatically adjusts how tight the timing belt/chain is. No slack (which causes slipping or skipping teeth) and no too-tight (which wears parts out fast). This makes sure the camshaft controls the valves right, matching up with the piston to keep the engine running efficiently.
Prevents Damage: Cuts down on belt/chain vibration and weird movement when the engine’s going fast. That stops expensive problems—like valves and pistons crashing (from bad skipping) or a broken belt that shuts the engine down.
Fits the Original System: Works with the Chery A13’s original timing setup and engine—no mods needed, just swap it in directly.
How It Works
It uses a
spring to adjust automatically. When the engine runs, the timing belt/chain stretches or vibrates from wear or heat. The strong spring inside 480-1007050 pushes the
tension pulley (or guide rail) to keep steady pressure on the belt/chain, fixing slack right away. When the engine stops, the spring eases up a bit—so the belt/chain isn’t stressed nonstop. There’s also a damping part inside that quiets noise and vibration, keeping it smooth.
3. What Makes It Good
Perfect OE Fit: Made to Chery’s original blueprints—mounting holes, bolt spots, and pulley size match the A13’s engine exactly. Even new mechanics can install it without drilling or messing with the engine bay—saves time and avoids mistakes.
Tough, High-Quality Materials: The housing’s heat-resistant ABS plastic, the pulley’s reinforced PA66-GF25 (handles up to 150°C—way hotter than the engine’s usual 90-120°C). The internal spring’s corrosion-resistant alloy steel—stays steady even after long use.
Works in Any Weather: Tested from -40°C to 80°C—good for freezing winters or hot summers, no loss of tension control. The pulley has smooth bearings and anti-friction coating—wears the belt/chain 30% less than cheap generic parts.
Quiet & Stable: The damping system soaks up vibration from the belt/chain—no rattling or squeaking like cheap tensioners. Makes driving smoother and extends the whole timing system’s life.
Safe & Compliant: Meets auto industry standards for timing parts—keeps tension consistent to avoid engine disasters. It’s designed to not suddenly lose tension, so it’s reliable for daily driving.
4. What It’s For
Vehicles: Only Chery A13 models. Check your car’s production year and engine setup to make sure it matches 480-1007050—no fit issues from model updates.
Scenarios: Must-have for regular maintenance (replace every 60,000-100,000 km, or as the car manual says). Also use it if you hear timing system noise, the engine loses power, or the belt slips—signs the old tensioner’s worn out.
5. Install & Use Tips
Install
Line Up Timing First: Before replacing, lock the engine’s timing marks (follow Chery A13’s service guide). If it’s misaligned, you could ruin the engine.
Clean & Check: Wipe dust, oil, and gunk from the mounting area. Check the timing belt/chain—if it’s cracked or stretched, replace it with the new tensioner to make the system last longer.
Tighten to the Right Torque: Use a torque wrench to tighten the mounting bolts to Chery’s specs (usually 18-22 N·m). Too tight bends the housing; too loose makes it wobbly.
Use & Maintain
Check Regularly: When you change oil, look for pulley wobble, spring rust, or oil leaks (if it’s hydraulic). If something’s wrong, replace 480-1007050 right away.
Don’t Overload: If you hear timing system noise, don’t tow heavy things or drive fast—that could mean the tension’s bad, and the belt/chain might break.
Only Use Genuine Parts: Never use cheap non-OE tensioners. They don’t control tension right, so the timing system fails early—and you’ll pay for expensive engine repairs.
