* The 2.3L 4-cylinder (F23A) is a non-interference engine. This is generally considered good news, as valve-to-piston contact is less likely to occur if the timing belt breaks.
* The 3.0L V6 (G20A) is an interference engine. This means if the timing belt breaks, the valves can collide with the pistons, causing significant engine damage.
Therefore, you must identify the specific engine in your 1998 Accord to know for certain. Check your vehicle's documentation or the engine bay for the engine code (F23A or G20A).
