if you are talking about the beetle bug there is no timing belt. the cam is run off the crank gear to the cam gear.
standard mileage for most all timing belts is 70,000 miles, but not many Jeeps have belts, they have chains that do not need to be replaced
It depends on the year.
There is no recommended replacement interval given for the chain replacement timing belts are critical, chains are not.
Timing chains never need to be changed, only belts.
A timing belt is often a toothed belt, but there are other places where toothed belts can be used as well.
Most reccomendations are between 60,000 and 100,000 miles
CR-V engines are equipped wiht timing BELTS not chains. The factory recommended replacement interval is 105,000 miles.
The Nissan Frontier with a 4.0-liter V6 engine uses a timing chain rather than a timing belt. Timing chains are generally more durable and have a longer lifespan than timing belts, often lasting the lifetime of the engine with proper maintenance. This design reduces the need for regular replacement, which is a common requirement for vehicles with timing belts.
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.
I believe that its just the timing belts that should be changed every 80,000 miles or so and not the chain. Belts exist in smaller four cylinder engines and in some six cylinder engines as well. Timing chains typically don't break any more often than other metal parts on the inside of your engine. A call to a dealer will get you more free and correct information. Good luck !!
I was looking at the 1999 Ford Escort scheduled maintenance guide and the Gates website ( they make timing belts etc . ) and both show to inspect the timing belt at 120,000 miles , replace if necessary ( that applies to both the 2.0 liter SOHC and DOHC engines )
The 1998 Buick Park Avenue Base is equipped with a timing chain, not a timing belt. Timing chains are generally more durable and have a longer lifespan than timing belts, often lasting the lifetime of the engine with proper maintenance.
