Technical Specifications

Vehicle Fitment

Engine details (verify with VIN):

• 2.0L I4 Ingenium Diesel (AJ200D / AJ20D4 / TD4 / SD4) – 150PS, 180PS, 240PS 

• 2.0L I4 Ingenium Petrol (AJ200P / AJ20P4 / Si4 / P250 / P300) – 240PS, 250PS, 300PS 

⚠️ Important: This tensioner fits 2.0L Ingenium engines only – not for 3.0L V6, 5.0L V8, or older engine variants. Confirm your engine type before ordering.

Signs of Failure

• Belt squeal or chirping – from the front of the engine, especially at cold start 

• Rattling or fluttering belt – visibly slack or oscillating tensioner arm 

• Pulley bearing noise – grinding or rumbling from the tensioner area 

• Accessory malfunction – alternator, water pump, or A/C issues due to belt slip 

• Poor charging performance – reduced alternator output 

💡 The tensioner spring weakens and the pulley bearings wear over time, leading to belt squeal, vibration, poor charging performance, or even belt failure. Replacing a worn tensioner restores stable belt tension and protects the engine from overheating or electrical faults caused by belt slip .

Critical – Verify Your VIN Before Ordering

Accessory drive tensioners are VIN- and engine-specific. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. It is standard practice to replace the tensioner together with the drive belt, since both wear together and share the same access. The idler pulley is often renewed at the same time .
