its a belt
If you dismount (unbolt) both the buckle and the belt portions from the '99 and substitute them for the matching pieces on an '03, they will be compatible.
As often as the manufacturer recommends
55000 miles max
100,000km
every 75,000 miles it is advised or after 7 years :)
Not if its the eco tec engine its chain driven
The 2003 Accord V6 has a cam belt that must be changed every 110,000 miles. The 4 cylinder Accord has a cam chain that requires no maintenance and should last the life of the engine.
I believe it has a chain instead of a belt. Call your Renault dealer to make sure.
