Up through the 2001 models CR-V's are quipped with timing BELTS that the factory recommends be replaced every 10 years or at 105,000 miles, whichever comes first. Starting with (and including) the 2002 models, the engines have timing CHAINS which do not require replacement.
It has a self tensioner, Most often you have to replace the chain it self if it is skipping time or is getting very loose.
There is no recommended replacement interval given for the chain replacement timing belts are critical, chains are not.
You don't as the 2004 Honda CRV uses a timing chain and not a belt. It should last the life of the engine.
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.
Timing chains will normally last the life of the engine. You replace it when the engine is overhauled or if it becomes noisy.
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.
you will replace the timing chain when mornig cold start becomes noisy Normally it will last the life of the engine, and is replaced when the engine is overhauled.
It should not need to be replaced under normal conditions.
V6 RAV4 seems to have a timing chain which does not need any periodic maintenance
If oil changes were kept up, never
If it is a chain, never. If it is a belt, usually around 100,000 miles. The break point on a 2000 civic is 120,000.
The 2003 Chevy Malibu does not have a timing belt. It has a chain which should last the life of the engine.
