⚠️ Common Signs of Failure

• Belt squeal or rib cracking
• Frayed edges or glazing
• Accessory under-speed
• Repeated belt tracking problems
• Belt failure from a seized pulley or tensioner

🛠️ Service Notes

• Fit the belt over the pulleys by hand and let the tensioner take it up — never lever a ribbed belt on with a screwdriver, which cracks the rib flanks and shortens its life
• Check that every rib sits in its pulley groove and that the belt runs central on each pulley before cranking the engine
• Inspect the tensioner and every pulley face while the belt is off; a rough bearing, a rusty tensioner arm or a scored pulley will destroy a new belt
• Note the routing before removal, then turn the engine over by hand once the new belt is on and re-check the run and tension following the procedure for your engine
• Keep oil, fuel and coolant off the belt, and renew a contaminated belt rather than trying to clean it
