or 6 years, which means for you the belt should have been changed already or is due now.
Get a reputable garage to examine the belts condition, and if not already done, get it
done asap. £1,200+ rebuild costs aren't worth the risk IMO :o
The Timing Belt should be changed along with the Tensioner & Idler Pulley, plus have the water pump
& bypass hose inspected as to replace them later means taking the timing belt off.
Timing belt approx £30
Tensioner approx £47
Idler Pulley approx £47
Water Pump approx £100
Hope this information helps mate :D
Are you sure the cambelt runs off the waterpump? Cant see anything that says that on the autodata mate.
