Belts and hoses
Your belts and hoses should be inspected every three months or 6,000 km—whichever comes first. A great time to have them inspected is during your regularly scheduled oil change.
Replace your belts if they are broken, excessively worn, cracked or more than five years old. Your belt tensioner and pulleys should also be inspected—and possibly replaced—at the same time your belt is installed.
The hoses that deliver coolant from your engine to your radiator will degrade from the inside out. Remember—when it’s time to replace your hoses, be sure to replace them all at once.
