- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C1, Peugeot 107
- Product Codes: 128143, 5708A0, 6822QX, 6822TH
- Additional Numbers: 128143, 5708A0, 6822QX, 6822TH
Function
The Tensioner Keeps The Accessory Drive Belt At The Correct Tension To Transfer Power From The Crankshaft To The Alternator And Air Conditioning Compressor. By Maintaining Proper Tension It Prevents Belt Slip, Reduces Noise (Squeal), And Minimizes Load On Bearings And Other Drive Components.
Replacement Procedure
Basic Steps For Replacement (General Guide):
- Park On A Level Surface, Engage Handbrake And Remove Ignition Key.
- Loosen Belt Tension Using The Appropriate Tool On The Tensioner To Relieve Tension And Remove The Drive Belt. Take Note Of Belt Routing.
- Remove The Fasteners Securing The Old Tensioner And Extract The Unit.
- Fit The New Tensioner In Place And Tighten Fasteners To Manufacturer Torque Specifications.
- Reinstall The Drive Belt Following Correct Routing, Reapply Tension And Rotate Engine By Hand To Ensure Alignment.
- Start Engine, Listen For Abnormal Noises And Recheck Fastener Tightness After Short Test Drive.
Installation Recommendations
- Always Disconnect The Battery Before Starting Work And Follow Manufacturer Procedures To Avoid Electrical Or Mechanical Damage.
- Use The Correct Tools And Observe The Manufacturer’s Torque Settings For Mounting Bolts.
- Inspect The Drive Belt, Pulleys And Idlers While Replacing The Tensioner; Replace Worn Or Cracked Belts And Damaged Pulleys.
- Ensure Proper Belt Alignment To Prevent Rapid Wear. After Installation, Recheck Tension And Fastener Tightness After A Short Run.
Typical Service Life And When To Replace
Accessory Belt Tensioners Commonly Last Tens Of Thousands Of Kilometres But Are Subject To Operating Conditions. They Are Often Replaced Along With The Drive Belt Or When Symptoms Appear — Such As Squealing Noise, Visible Play In The Pulley, Or Belt Slippage. As A Practical Rule, Inspect At Regular Service Intervals (For Many Vehicles Around 60,000–100,000 Km Depending On Use) And Replace If Any Signs Of Wear Or Bearing Noise Are Present.
Why The Part Most Commonly Fails
Common Failure Causes Include Bearing Wear, Loss Of Spring Tension, Contamination From Oil Or Coolant Leaks, And Excessive Heat Or Corrosion. Misaligned Pulleys Or A Worn Belt Can Also Accelerate Tensioner Failure. Replacing The Tensioner Prevents Secondary Damage To The Belt, Alternator, And Compressor Pulleys.
Notes For Professionals And Enthusiasts
This Tensioner Is A Direct-Fit Replacement Frequently Identified By Its Product Codes (128143 / 5708A0 / 6822QX / 6822TH). Keep The Vehicle’s Service Manual Handy For Specific Torque Values And Any Model-Specific Removal Steps. Proper Installation Restores Drive System Reliability And Reduces The Risk Of Belt-Related Breakdowns.
