Its possible to clean but much easier to just replace. takes an hour to clean, 10 minutes and 6.50 dollars to replace. better for engine too.
You don't clean the oil filter you replace it.
The same way as you'd change it on any other car. Raise the car, put it on ramps or jackstands, remove the oil drain plug from the oil pan making sure you have a catch pan for the oil. Let it drain until all of the dirty oil is drained into the catch pan. Reinstall the drain plug, put your catch pan under the oil filter, remove the filter and let it drain. Clean the mounting surface where the old filter came off, put some clean oil on the gasket of the new filter, spin it on until snug, turn it an additional 3/4 turn, put in the new oil and off you go. Check your owners manual or the parts store to find out how much oil you'll need. If it's the 1.6, three quarts. If it's 1.8, three and one half quarts.
On a car, the oil filter should be replaced when the oil is changed. First, drain the crankcase. Then, using an oil filter wrench, remove the old filter, having a receptacle underneath it to catch the drip (it is full of oil). Use a rag to clean the surface that the oil filter's gasket rests against. Take the new filter, and fill it to the top with oil - once. You will see the oil "disappear" as the filter medium soaks it up, but don't fill it a second time. Oil the new gasket on the oil filter with fresh oil. Spin it on, and tighten by hand 3/4 of a turn. Refill the crankcase, run the engine and check for leaks.
Run your car up on ramps. Make sure you have a catch can to catch the oil. About 4 feet back from the front, you will find a large, black, flat area, with a bolt at the end of it. Slowly unloosen the bolt (lefty loosey)--be ready to catch the oil. Leave it for awhile to fully drain. Clean bolt, wipe off the opening, put bolt back in and tighten. Take the oil filter out slowly as well. Don't turn it over until you get it down, then dump it in the catch can. Wipe the opening where the filter was. Wipe a small amount of new oil around the gasket on the new filter, screw it in, once it's tight--just another quarter turn. Fill oil. Start car. Check oil level with dipstick.
Assuming you mean oil pump, changing the engine oil and oil filter on a regular basis with quality motor oil will help keep the internal engine parts as clean as possible.
The answer depends on which engine your car has. Wear gloves to keep the oil off of your skin. If it is the 2.8L V6 the filter mounts on the lower block on the side nearest the radiator. Put down a drain pan to catch leaking oil. Simply unscrew the old filter, clean the mounting surface on the block, put a light coat of engine oil on the rubber seal and screw the new filter on hand tight. Refill the crankcase, run the engine and check for leaks. Also check the oil level and replenish as needed. It it is the 2.5L 4 cylinder engine the filter is in the pan. You will find a largish nut on the bottom of the pan. Put a drip pan under it to catch the oil and take the plug off. The filter with the oil will come out. Clean the mounting surface and lightly oil the seal, put the filter in and put the plug back on. Refill the crank case with oil. Check for leaks and check the oil level, replenish with oil as needed.
No oil filter, no oil, lots of damage.
The oil will never completely drain out of an oil filter until you take it off and flip it upside down on your oil catch pan, they are not designed to. If the mess from dripping oil is what you are trying to avoid then all I can say is use rags to keep the car clean and rubber gloves for your hands.
air filters clean the dirt while oil filters strain the used oil eliminating the tiny metal shavings from the engine
clean the surface that the oil filter seals to, sometimes the gasket from the old filter will stick, or there could be rust/dirt on that surface and it isn't sealing properly.
