How do i change oil and oil filter on2000 kia sportage 4 wheel drive 4 cylinder

It isn't too hard a job it's just a messy one. The oil filter type might depend on the version of the engine yours is fitted with. This method is for the basic 'screw on' type.
I have attached a series of videos that will be a rough guide to doing this job.
Raise the front of the vehicle and support it on axle stands. The drain plug will be a larger size bolt on the lowest part of the sump, (oil pan), on the engine.
I usually use a large sheet of cardboard on the floor with an oil catch pan on top of it.
Carefully loosen the drain plug one turn. It should start to leak oil. Gently remove the plug 'by hand' so you don't drop it in the oil pan with the used oil. Let it drain until it's a steady Slow drip. Clean the drain plug and the hole it came out of then refit the plug.
**NOTE** fit the plug by hand until it stops THEN just turn it a small amount tighter with a spanner or socket. It does NOT need to be in super tight, about 20 to 25Nm as a torque setting.
Dispose of the old oil safely. Some mechanic shops will accept it for safe disposal.
Facing the rear of the vehicle and looking down on the engine, the filter should be on the left side about half way down. Remove it from underneath as access will be better. It should only be in 'Hand Tight' but you might need a 'strap' or 'filter' tool to loosen it at first.
** The filter will have oil in it and oil will leak out of the filter mount hole so use your drip pan to catch the spillages**.
Make sure you have the old filter oil seal ring as they sometimes stay stuck to the engine block.
Clean all the exposed faces as best you can. Pour a small amount of oil into the filter and rub a small amount of oil over the new oil seal ring to stop it wrinkling up when you re-fit it. Re-fit the new filter by hand until it is nice and tight.
**NOTE** This is tight enough. You don't need a tool to tighten it!
Check the sump plug is refitted and the oil filter is in place. Wipe clean any spills made during refitting.
Check your owner's manual for the type and amount of oil needed and refill the engine. Once filled walk away for about ten minutes before you check your oil levels. When it is correct start the engine, let it settle into a smooth idle then check under the vehicle for leaks from the sump plug and the filter housing. No leaks means a good job done. Lower the vehicle back onto the ground.
Give it two or three days of use and re-check for leaks and your oil level. No leaks and a steady oil level is a job well done. https://www.carcarekiosk.com/video/2002_Kia_Sportage_2.0L_4_Cyl._Sport_Utility_(4_Door)/oil/change_oil_and_oil_filter
