The 2.4l does, change at 100,000 miles.
Depends on the year, mileage, condition, options, etc...

Depends on overall condition, mileage, options, etc...
The timing chain (not belt) is not a thing that you should have to replace on a mileage basis. Just keep the engine in tune, change the oil per manufacturers recommendations, and drive it. By the way, a timing belt should be changed approximately every 75K to 80K miles. Your engine will have a chain.
It does not have a timing belt, it has a timing chain that requires no maintenance.
The 2004 2.0 liter Pontiac Grand Am does not have a timing belt, but instead has a timing chain which requires no maintenance.
about 100,000 mile if it,s a timing belt
You did not specify as to the year. If it does not have a distributor then the computer takes care of it.
It will change to the mileage on the new speedo.
The timing chain does not require replacement unless it has failed.
It does not have a belt, it has a chain.
