The timing belt needs to be replaced about every 100k miles. Actually the recommended interval is 105,000 miles. You also replace the tensioner and idler pulley at this time
Timing chain usually needs to be replaced each 180-200K miles.
What you meant to ask is how often should the timing belt be replaced! And the answer is every 90,000 miles for b2000 model.Ok
Every 90K miles.
It should not need to be replaced under normal conditions.
You MUST replace the cam belt every 50,000 miles on this Volvo. Warning: This is an interference engine.
It doesn't have a timing belt...it has a metal timing chain...these do not standardly wear out for a very long time.
You should never have to replace it. The timing chain is designed to last the life of the engine. It is normally replaced when the engine is overhaul.
The Prizm has a timing CHAIN, not belt. The timing chain does not get replaced on a scheduled interval. It should never need to be replaced. The serpentine belt, however, does need to be replaced. Inspect the belt for cracks and glazing, and replace. It is not a difficult DIY job. It is easiest to do it from under the car, after removing the splash pan.
Only the 4 cylinders have a belt. The belt should be replaced at 60,000 miles.
Unless a timing chain is making a noise or has jumped a tooth, they need not be replaced. Timing belts need changing according to the specs spelled out in the owner's manual.
Timing chains are designed to last the life of the engine. They are normally replaced during a complete engine overhaul. Unless the chain becomes noisy no maintenance is required.
every 60,000 miles or 24 months
