On the 2000-2015 Renault Clio, the timing belt tensioner bearing on Clio K-series engines can fail before the scheduled belt replacement interval, causing catastrophic engine damage. The water pump, which is driven by the timing belt, also fails prematurely.

Common Symptoms

  • Squealing from timing cover
  • Coolant leak from water pump
  • Timing belt wear visible
  • Ticking noise

How to Fix

Replace the timing belt, tensioner, idler pulley, and water pump as a complete kit every 72,000 miles or 5 years, whichever comes first. Do not skip the water pump replacement.
