Engine Lubrication System - Hev: Other Kia Optima III

Selection Of Engine Oil

Recommendation (except Middle East): 5W-20/GF4&SM (If not available, refer to the recommended API or ILSAC classification

API classification: SL, SM or above

ILSAC classification: GF4 or above

SAE viscosity grade: Refer to the recommended SAE viscosity number

Scheme 39

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

1. Remove the timing chain. (Refer to «TIMING CHAIN»(ref-535722-S42535801322013031200000)
2. Install a stopper pin (A) after compressing the balance shaft chain tensioner.
3. Remove the balance shaft chain hydraulic tensioner (B).
4. Remove the balance shaft chain tensioner arm (C).
5. Remove the balance shaft chain guide (D).
6. Remove the balance shaft & oil pump module (A) with the chain (B) and sprocket (C).

1. The key of crankshaft should be aligned with the mating face of main bearing cap. As a result of this, the piston of No. 1 cylinder is placed at the top dead center on compression stroke.
2. Confirm the balance shaft & oil pump module timing mark. Timing marks to be visually aligned with centers of adjacent cast timing notches.
3. Install balance shaft & oil pump module (A) with the chain (B) and sprocket (C). NOTE: The timing marks of balance shaft & oil pump module sprocket and crankshaft sprocket should be matched with the timing marks (color link) of balance shaft chain. Tightening order Tighten the bolts in order number as shown with seating torque 29.4 N.m (3.0kgf.m, 21.7 lb-ft) and then loosen the bolts as reverse tightening order (6-5-4-3-2-1). Using the SST (09221-4A000), tighten the bolts as specified tightening order in same increments as follows. Tightening torque: Bolts (A) (M9x181.5): 22.6~26.5N.m (2.3~2.7kgf.m, 16.6~19.5lb-ft) + 88~92° Bolts (B) (M9x95): 22.6~26.5N.m (2.3~2.7kgf.m, 16.6~19.5lb-ft) + 43~47°
4. Install the balance shaft chain guide (D). Tightening torque: 9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
5. Install the balance shaft chain tensioner arm (C). Tightening torque: 9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
6. Install the balance shaft chain hydraulic tensioner (B) then remove the stopper pin (A). Tightening torque: 9.8 ~ 11.8N.m (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft)
7. Confirm the timing marks.
8. Install the timing chain. (Refer to «TIMING CHAIN»(ref-535722-S42535801322013031200000)

Scheme 49

1. Check the continuity between the terminal and the body with an ohmmeter. If there is no continuity, replace the oil pressure switch.
2. Check the continuity between the terminal and the body when the fine wire is pushed. If there is continuity even when the fine wire is pushed, replace the switch.
3. If there is no continuity when a 50kPa (0.50kgf/cm 2 , 7.25psi) is applied through the oil hole, the switch is operating properly. Check for air leakage. If air leaks, the diaphragm is broken. Replace it.
