Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Repair Procedures: Inspection: Notes
- Check the engine oil quality.
Check the oil deterioration, addition of water or coolant, discoloring or thinning.
If the quality is visibly poor, replace the oil.
- Check the engine oil level.
Warm up and stop the engine, and then wait 5 minutes before checking whether the oil level is between the "F" and "L" marks in the dipstick.
If the level is lower than "L", check for leakage and add oil up to the "F" mark.
- Do not fill with engine oil above the "F" mark.
