When is the timing belt due on a 2002 4 popper caravan? Our manual is gone.

 

The gates database says 120K. Don't quote me on that, you can look for yourself, gates.com, timing belt link. It also says the 2.4 dohc engine vin B is an interference engine. If that is the case, if the belt even looks worn, replace it, I don't care how many milesthe belt has on it.

 

I believe the serive manual say 100K but not 100% sure depending on the motor might want to change the water pump while your at it

 

90,000 miles or 144,000 km.
You can down load the 2004 owners manual which is very similar from the Dodge web site:
