Servicing - A/t: Maintenance Daewoo Nubira II

SERVICE INTERVALS

Check transaxle fluid level and condition every 15,000 miles. Under normal operating conditions, the transaxle fluid does not need to be replaced. Under continuous extreme operating conditions (trailer towing, heavy city traffic with ambient temperature more than 90°F (32°C) or delivery service), fluid and filter should be changed every 45,000 miles.

CHECKING FLUID LEVEL

1. Start the engine and allow the engine to idle for approximately 5 minutes, or if possible, drive the vehicle for a few miles to warm the transaxle fluid. Check the fluid level when the transaxle is above 104°F (40°C).
2. Park the vehicle on a hoist, inspection pit or similar raised level surface. The vehicle must be level to obtain a correct fluid level measurement.
3. Place a fluid container below the fluid level plug.
4. Press the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to Park position.
5. Remove the fluid level plug. (Scheme 76) Because the transaxle operates correctly over a range of fluid levels, fluid may or may not drain out of the plug hole when the plug is removed.
6. If fluid does not drain through the plug hole after adding a total of 1.5 liters, the transaxle was either under filled or is leaking fluid. Inspect the transaxle for fluid leaks. Fix any leaks before setting the transaxle fluid level.
7. Install the fluid level plug. Tighten to specification. See «TORQUE SPECIFICATIONS»(ref-151661-S27468387212003010600000). When the fluid level checking procedure is completed, wipe any fluid from the transaxle case with a rag or shop towel. Also, check that the fluid fill cap and the vent tube are properly installed.

Draining

1. Disconnect the negative battery cable. Place drain pan under transaxle.
2. Remove the 12 oil pan bolts. Remove the oil pan. Allow fluid to drain. (Scheme 77) The magnet can remain in the oil pan.
3. Remove the oil pan gasket. The oil pan gasket is reusable.
4. Remove the transaxle filter and neck seal. (Scheme 78)
5. Flush the oil cooler. See «OIL COOLER FLUSHING»(ref-151661-S07146654362003012100000).

Refilling

1. Install the transaxle fluid filter and the filter seal. (Scheme 78)
2. Install oil pan and gasket. (Scheme 77) Tighten oil pan to specification. See «TORQUE SPECIFICATIONS»(ref-151661-S27468387212003010600000).
3. Remove fluid level plug. Add recommended transaxle fluid. See «RECOMMENDED FLUID»(ref-151661-S20600316602003010600000).
4. Install fluid level plug and tighten to specification. See «TORQUE SPECIFICATIONS»(ref-151661-S27468387212003010600000).
5. Connect the negative battery cable.

OIL COOLER FLUSHING

1. Disconnect both cooler lines from the transaxle. (Scheme 79)
2. Place a hose over the end of the cooler inlet line (from the top of the cooler) and inset the hose into an empty container.
3. Flush clean transaxle fluid through the return line (from the bottom of the cooler) using an oil suction gun until clean transaxle fluid comes out of the hose. This will back flush the cooler.
4. Remove the hose from the inlet cooler line and place it on the return line.
5. Flush clean transaxle fluid through the inlet line until clean transaxle fluid comes out of the return line. Remove the remaining transaxle fluid with compressed air. Flush with NEW transaxle fluid.
6. Reconnect the oil cooler lines to the transaxle. (Scheme 79)
