Restore the smooth, quiet, and reliable performance of your family MPV with the premium Gaido Fan Belt Tensioner.

Is your Naza Ria or Kia Carnival making a loud chirping or grinding noise from the engine bay, especially when idling or turning the steering wheel? These are common symptoms of a failing automatic serpentine belt tensioner. The Gaido Fan Belt Tensioner is a high-precision replacement specifically engineered for the heavy-duty 2.5L KV6 engine. 
Maintaining precise tension is critical for the large accessory drive system in these MPVs. This Gaido tensioner assembly ensures your serpentine belt stays aligned and under constant pressure, preventing slippage that can lead to poor alternator charging, heavy power steering, and inefficient air conditioning—essential for long family trips.
