Not sure what engine you have. My pathfinder has the 3.5L engine and it has a timing chain. I've heard that the timing chain doesn't need to be replaced until the engine wears out and requires a complete rebuild.
The 2002 MDX has a timing belt that has to be changed at 160,000KM.
It has a timing belt which must be changed every 106,000 miles.
The engine in that vehicle doesn't have a timing belt.

Timing belt
The 2002 Accent booklet states that the Timing Belt should be changed at 60,000 Miles.
A mechanic old me about 100,000K
The 2002 V6 has a timing belt that MUST be changed every 105,000 miles.
