Engine Oil. Repair procedures

Oil and filter replacement
  
•
Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
  
•
Prolonged and repeated contact with mineral oil will result in the removal of natural fats from the skin, leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause skin cancer.
•
Exercise caution in order to minimize the length and frequency of contact of your skin to used oil. Wear protective clothing and gloves. Wash your skin thoroughly with soap and water, or use water-less hand cleaner, to remove any used engine oil. Do not use gasoline, thinners, or solvents.
•
In order to preserve the environment, used oil and used oil filter must be disposed of only at designated disposal sites.
1.
Drain the engine oil.
(1)
Remove the oil filler cap (A).

(2)
Remove the oil drain survice cover (A).
Tightening torque :
7.8 - 11.8 Nm (0.8 - 1.2 kgf.m, 5.8 - 8.7 lb-ft)

(3)
Remove the oil drain plug (A) and drain the oil into a container.

2.
Replace the oil filter.
(1)
Remove the oil filter survice cover (A).
(2)
Remove the drain bolt (A) on the bottom of the oil filter cap and drain the oil in the oil filter.
(3)
Remove the oil filter cap (A).
(4)
Install the new oil filter element (C).
Lightly screw the oil filter cap into place, and tighten it until the O-ring (B) contacts the seat. Finally tighten it again by specified tightening torque.

  
•
Make sure to drain the engine oil first before replacing the oil filter. If not, the oil may spill on the oil pan assembly side when removing the oil filter and may be mistaken for leakage.
•
Always use new O-ring.
•
Wipe off the oil and foreign substances remaining inside the filter housing, threads and cover cap threads as much as possible.
※ If the residual oil is not removed, it may leak between the cover cap and the housing mating surfaces, which can be mistaken for oil leakage. (The amount of leaking oil and the leaking period may differ depending on the amount of residual oil)
•
When assembling the gasket, pay attention to the protrusion direction (A).
If assembled in reverse, gasket lifting and leakage may occur.
•
After assembling the gasket to the cover cap groove, make sure to press it in the whole circumferential direction (360°) with fingers so that the entire gasket is seated sufficiently.
※ If the gasket is seated incompletely, leakage may occur.
•
Remove the foreign substances on the gasket seating surface and inside the cover cap/housing mounting areas.
•
Apply minimum amount of oil to the new gasket surface to prevent possible gasket damage.
(5)
Replace the O-ring (B) of the drain bolt with a new one. Tighten the drain bolt (A) by specified tightening torque.
Tightening torque :
4.0 - 5.0 N.m (0.41 - 0.51 kgf.m, 0.90 - 1.12 lb-ft)

  
•
Assemble the drain plug to the specified torque using a torque wrench.
※ When manually assembling the drain plug using a hexagonal wrench, it may result in the damage to the drain plug or leakage due to the failure to comply with the specified torque.
3.
Refill with the engine oil.
(1)
Clean and install the oil drain plug (A) with a new gasket (B).
Tightening torque :
34.3 - 44.1 N.m (3.5 - 4.5 kgf.m, 25.3 - 32.5 lb-ft)

(2)
Fill with fresh engine oil after removing the engine oil level gauge.
Capacity
Total :
6.8 L (1.80 U.S.gal., 7.19 U.S.qt., 5.98 lmp.qt.)

Drain and refill including oil filter and oil cooler :
5.8 L (1.53 U.S.gal., 6.13 U.S.qt., 5.10 lmp.qt.)
(3)
Install the oil filler cap (A) and oil level gauge.
4.
Start engine and check for oil leaks.
5.
Recheck the engine oil level.
Inspection
1.
Check the engine oil quality.
Check the oil deterioration, entry of water, discoloring of thinning. If the quality is visibly poor, replace the oil.
2.
Check the engine oil level.
After engine warm up stop the engine wait 15 minutes then check the oil level. Oil level should be between the "L" and "F" marks on the dipstick. If low check for leakage and add oil up to the "F" mark.
  
Do not fill with engine oil above the "F" mark.
Selection Of Engine Oil
Recommendation :
–
Middle East : 5W-30 ACEA A5/B5 or 0W-30 ACE C2
–
EUROPE : 0W-20 API LATEST(SN PLUS) or ACEA C5
Classification :
SAE viscosity grade : Refer to the recommended SAE viscosity number

  
For best performance and maximum protection of all types of operation, select only those lubricants which :
1)
Satisfy the requirement of the API, ILSAC or ACEA classification.
2)
Have proper SAE grade number for expected ambient temperature range.
3)
Lubricants that do not have both an SAE grade number and API, ILSAC or ACEA service classification on the container should not be used.
