Engine Care

How to Check the Engine Oil Level

  • With the engine at operating temperature and turned off, check the oil level on the dipstick.To get a true reading, the vehicle should be on a level spot.
  • After turning off the engine, wait a few minutes for the oil to drain back into the bottom of the engine.
  • Pull out the dipstick and wipe it with a clean rag.
  • Re-insert the dipstick. Push it in as far as it will go or the reading will not be correct.
  • Pull the dipstick out and look at the oil level on the end.
  • Caution: Be careful not to touch the hot exhaust manifold

How & When to add oil?

  • If the oil level is below or only slightly, above the low level, add engine oil of the same type as already in the engine.
  • Remove the oil filter cap and add engine oil in small quantities at a time, checking the dipstick.
  • When the level reaches within the correct range, install the filter cap and hand-tighten.

How to Check the Engine Coolant Level

  • Look at the see-through coolant reservoir when the engine is cold.
  • The coolant level is satisfactory if it is between the “F” and the “L” lines on the reservoir.
  • If the level is low, add coolant of the same type as already in the system.
  • The coolant level in the reservoir will vary with engine temperature, however if the level is on or below the “L” line, add coolant.
  • Bring the level up to the “F” line.
  • Always use the same type of coolant as already in the cooling system.
  • If the coolant level drops within a short time after replenishing, there may be a leak in the system.
  • Visually check the radiator cap, drain plug and water pump.
  • If you can find no leak, have your Lexus dealer test the cap pressure and check for leaks in the cooling system.
  • Caution: To prevent burning yourself, do not remove the radiator cap when the engine is hot.

What Coolant Type Must I Use?

  • Use only genuine Lexus Long Life Coolant 50% mixture.
  • Notice: Do not use alcohol type antifreeze or plain water alone.
