Here is a step-by-step guide to locate the engine oil filter in the Lexus RX300:
1. Open the hood of your Lexus RX300.
2. Locate the oil filter housing on the driver's side of the engine compartment, near the oil pan.
3. The oil filter housing is a cylindrical container that has the oil filter inside it.
4. Remove the oil filter housing cap by turning it counterclockwise.
5. Once the oil filter housing cap is removed, you will be able to see the oil filter.
6. Grab the oil filter and turn it counterclockwise to remove it from the housing.
When installing a new oil filter, make sure to:
1. Lubricate the gasket on the new oil filter with a small amount of new oil.
2. Screw the new oil filter into the housing by hand until it is snug.
3. Tighten the oil filter housing cap by turning it clockwise until it is snug.
Note: You may need to use an oil filter wrench to loosen or tighten the oil filter housing cap.
