How often should the Focus timing belt be replaced?

[DelNadia]

The replacement interval for the Focus timing belt is 8 years or 150,000 kilometers. The fact that the timing belt hasn't broken doesn't mean there are no issues. As the belt ages with use, its stretching will inevitably exceed the compensation range of the tensioner, causing the timing sprocket to slip. Additionally, tooth wear or oil contamination can also lead to slippage. Reference information: During inspection, if the belt shows signs of hardening, abrasion, fiber breakage, cracks, or fissures, it indicates the belt is damaged and should not be used further. Next, check for sprocket faults. Damaged sprockets can 'burn' belt material and accelerate tooth wear. Sprocket issues may also increase resistance from the valve mechanism on the timing belt. For all engines equipped with timing belts, manufacturers have strict requirements to replace the timing belt and accessories at specified intervals. The replacement cycle varies depending on engine structure, generally recommended between 60,000-100,000 kilometers. The exact replacement interval should follow the vehicle's maintenance manual specifications.
