SOURCE: How do you change the oil filter on a Hyundai Accent 1998/99?

CHANGING ENGINE OIL Be careful not to burn yourself, as the engine oil is hot. 1. Run the engine until it reaches normal operating temperature. 2. Stop the engine. 3. Remove the oil filler cap (on rocker cover) and the drain plug (on the oil pan). Drain the engine oil. 4. Re-install and tighten the drain plug to the specified torque. 5. Fill new engine oil through the oil filler. a. Cover the generator with a shop towel before pouring the engine oil to ensure that if oil spills, it will not drop on the generator. b. Use a funnel to pour in the engine oil. 6. Install the oil filler cap. 7. Start and run the engine. 8. Stop the engine and then check the oil level. Add oil if necessary.

Their shop website says below but you can call the service department. usually you want to tighten it just until it starts to not rotate freely then back off just a little bit. It should spin freely.

Hub bearing starting torque [Limit] : 1.8 Nm (18 kgf·cm, 1.33 lbf·ft) or less

It just pulls out of the geat box, it has a internal snap ring, they can really bwe a bear if they're being pulled for the first time.

This post is about a month old but maybe someone else will see it and it will help them. For this particular type of vehicle I would recommend NGK plugs (available at most parts places) NAPA has the Belden Maxx spark plug wires which work great. Make sure if you are doing this yourself that the plugs are properly gapped, even if they say they are pre-gapped from the factory check it and do it yourself if needed. As far as the coil if you are talking about what is refered to as coil pack(s) then re-doing the plugs and going with new plug wires should solve your problem. Generally if the plugs or wires are bad they can cause the coil pack(s) to go bad as well

We had the same problem. Turned out to be the alternator failing. Replaced it and problem went away. That was nearly 13 months ago.
