1. Start by warming up the vehicle's engine for a few minutes. This will help to loosen the oil and make it easier to drain.
2. Next, turn off the engine and locate the oil filter housing. On a 1991 Prelude, it is typically located on the passenger side of the engine, just below the valve cover.
3. Once you have located the oil filter housing, place an oil drain pan underneath it to catch the old oil as it drains out.
4. Use a wrench to loosen the oil filter cap and then remove the old oil filter by hand. Be careful not to spill any of the old oil.
5. Inspect the old oil filter for any signs of damage or debris. If the filter is damaged, it will need to be replaced.
6. Apply a thin coating of new oil to the gasket of the new oil filter. This will help to create a seal and prevent leaks.
7. Screw the new oil filter onto the oil filter housing until it is snug.
8. Replace the oil filter cap and tighten it until it is snug.
9. Finally, add new oil to the engine according to the vehicle's specifications.
