Genuine Ford Ranger & Everest 2022–2025 Accessory Belt Tensioner – MB3Z6A228A is an important part of the engine drive system, responsible for maintaining proper tension on the accessory belt (serpentine belt), helping components such as the alternator, water pump, air conditioning compressor, and power steering operate smoothly and in sync.
This genuine Ford product is designed with a heavy-duty spring and high-quality ball bearing, helping reduce vibration, prevent belt slip, and extend the life of the drive system.
When the tensioner is worn or damaged, the vehicle may experience the following:
The belt squeals, slips, or sags on startup.
Reduced alternator performance, weak A/C, or inconsistent water pump operation.
In some cases, the belt may break, posing a risk to the engine.
Replacement advice:
Check the tensioner every 40,000–60,000 km or when replacing the accessory belt.
If you notice unusual noises, bearing play, or belt sag, replace it immediately to avoid damage to other parts.
When replacing the tensioner, use genuine Ford parts to ensure the highest accuracy and durability.
It can also be replaced together with the accessory belt and idler pulley for optimal performance.
