Kia Optima Hybrid: Hydraulic System / Fluid Repair procedures
When checking the ATF level, be careful not to enter dust, foreign matters, etc. from fill hole.
1.
Remove the air duct (A).
2.
Remove the eyebolt (A).
3.
Add ATF SP-IV 700cc to the ATF injection hole (A).
4.
Start the engine. (Don’t step on brake and accelerator simultaneously)
5.
Confirm that the temperature of the A/T oil temperature sensor is 50~60°C(122~140°F) with the GDS.
6.
Shift the select lever slowly from “P” to “D”, then “D” to “P” and repeat one more at idle.
Keep on each speed position more than 2 sec.
7.
Remove the under cover (A).
8.
Lift the vehicle, then remove the ATF level plug (A) from the valve body cover.
At this time, the vehicle must be a horizontal state.
9.
If the ATF flows out of the overflow plug in thin steady
stream, the ATF level is correct. Then finish the procedure and tighten
the ATF plug.
ATF level excess:
Drain quantity exceed 900cc for two minutes. 50~60°C (122~140°F)
ATF level shortage:
No ATF flows out of the plug.
Do not reuse the O-ring of ATF level plug.
10.
Install the under cover (A).
Tightening torque :
7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)
11.
Install the eyebolt.
Eyebolt tightening torque:
2.9 ~ 4.9 N.m (0.3 ~ 0.5 kgf.m, 2.2 ~ 3.6 lb-ft)
Do not reuse the O-ring (A) of eyebolt.
12.
Install the air duct (A).
Tightening torque:
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)
1.
Remove the ATF drain plug (A) and reinstall the ATF drain plug after draining ATF totally.
Do not reuse the gasket of ATF drain plug.
2.
Fill the transaxle with ATF (about 5 liters).
