Your Honda Accord LX has only one engine available for the 1999 model year. Honda uses their 3.0L engine for the LX model and it is classified as a non-interference engine. Why is this engine designation important to you? The designation of non-interference means that if your valve timing gets off due to the belt failing, you will not have valves contacting the pistons and causing internal engine damage.
The 1999 Honda Accord LX uses a timing belt, and it has a maintenance replacement interval of 105,000 miles or 7 years, whichever comes first.
