2002 Elantra

Wife has a 2002 Elantra with 46000 miles. Is the 4 cylinder engine an interference engine and what is the recommended mileage to replace the timing belt?
From the factory, does anyone know what type of spark plugs were used - platinum, iridium, copper? and also the recommended mileage to replace the plugs.
Thanks

Four years or 60,000 miles

Probably platinum, but any type of plugs will work. The NGK V-Power copper plugs are popular, as they provide better performance than platinum or iridium plugs at a bargain basement price (<$2 each). The downside is that you have to change them more often (~every 30K).
Your original plugs should be good for ~60K miles if they're platinum.

Answers to both should be in the owners manual.

Actually -
a) Information about an engine being an interference engine would never be in the owner's manual. Service manual (the one that costs a good bit of money and does not come with the car), yes, maybe even possibly the maintenance guide that does come with your car, though usually that only lists the change interval;
b) The '02 Elantra 2.0L 4-cylinder IS an interference engine. And while one should not dismissively ignore maintenance intervals, the Elantra has had a reputation of being able to do a little better than the 4-year, 60,000 miles. I bought mine at 77,000, had it replaced immediately, and was surprised how good the old one looked. Mechanic said the same thing.

You don't have to pay a dime for the service manual. Simply go to www.hmaservce.com, sign up for a free account and you can access the manuals for any Hyundai vehicle free of charge. Two caveats are that the site only works with IE and you need to download a viewer from Adobe using the link provided on the site.

I would not try that. My sister had a Hyundai Elantra which she bought new and the belt failed at 62,000 miles and destroyed the engine.. She was not aware that the belt has to replaced at the recommended intervals to prevent such events from happening. Why gamble for 6 months more driving and risk an expensive engine failure??
