There is no maintenance on the timing chain unless it breaks. No you don't change it.
what engine do you have in your impala?
The 3.4 liter V6 engine in a 2001 Chevrolet Impala has a timing CHAIN
Every 10,000 miles
It don't have a timing chain and if it did it would out last the engine. It should have a timing belt and it should be replaced about 60 thousand miles. Sorry I must disagree with my friend who is very knowledgable. The 3.5 Liter and 3.9 Liter Chevy V6 has a timing chain and not a belt. The chain will last the life of the engine.
it has a timing chain
There is no timing belt in that engine. It has a timing chain.
It does not have a timing belt, That engine has a timing chain and gears and they normally last the life of the engine.
When it go's out and the engine quits are when you can no longer set the timing with an engine scanner.

chevy luminas 3.1 engine does not have a timing belt. it does have a timing chain that will last well up to 200,000 miles
It is either time for a oil and filter change or the engine is low on oil.
All Chevrolet Impala's have a chanin that requires no maintenance or replacement under normal conditions.
