Does the 93 have. A timing belt or chain?
Ask your local auto parts store, they can look it up. It may depend on your specific engine, the 2003 Honda Accord used a chain on the 4 cylinder but a belt on the V6.
The belt should (usually) be replaced every 60000 miles (100000 km), while the chain should last the life of the engine (150000+ miles).
On many engines, if the belt breaks, it can cause expensive damage to the valves and/or pistons, so you want to make sure you replace it as scheduled.
