It should last as long as the engine.
Unless there is something wrong with it (there shouldn't be), you should never have to replace the timing chain. That's the beauty of chevy.
If the engine has a timing belt, it should be changed around the 150K mark. If there is a timing chain, it does not have to be changed unless it is damaged.
When you here a rattling noise from the engine at idle.
When you overhaul the engine. It is designed to last the life of the engine.
The chain will last the life if the engine and does not require changing.
You don't as the 2004 Honda CRV uses a timing chain and not a belt. It should last the life of the engine.
I think they recommend to change it each 160-180K miles.
the 2001 does not have a timing belt,instead a timing chain,which does not required replacement as often as belt
It should last the life of the engine and is normally replaced during an engine overhaul.
You don't! It's a timing chain! Just make sure you change oil regularly
Timing chain usually needs to be replaced each 180-200K miles.
