Every 105,000 miles. On the 4 cylinder you should also change the balance shaft belt. On both the 4 cylinder and the V6 the water pump is driven by the cam belt, so change the water pump at the same time you change the cam belt to save labor costs as the pump will not last much over 105,000 miles. These engines are interference engines. If the belt breaks you will have serious engine damage. Do not neglect this service.
Every 110,000 miles on the V6 and never on the 4 cylinder.
I don't know about 2006, in the 2001 it's at 105k miles
Every 90,000 mile under normal conditions or every 60,000 miles under severe conditions.
15000 miles
Honda recommends @ 45k miles and then every 30k miles after that.
I recommend every 75,000 miles.
definitely going to have a belt. chains are not used often anymore
Honda recommends changing it at 100,000 miles. I personally recommend you change it every 75,000 miles. The 2003 Honda Accord had problems with the transmission so I would recommend this as a preventative measure.
Every 100,000 miles
You don't as the 2004 Honda CRV uses a timing chain and not a belt. It should last the life of the engine.
Change it every 5 years or 60,000 miles whichever come first.
Every 50,000 miles or 5 years. Read your owners manual maintenance schedule.
