Ssangyong Korando 2010 Service Manual – AWD System Factory Specs

I’ve seen too many guys try to diagnose a Korando AWD issue using generic internet advice. Then they end up replacing the e-coupling when the problem was low oil level in the PTU. This 40-page factory service manual for the Ssangyong Korando 2010 Service Manual gives you the actual specs – gear ratios, oil types, assembly procedures – straight from the OEM. No aftermarket guesswork.

Page 3 lists the exact gear ratio for the Power Transfer Unit: 2.929. Helical gears: 22/39. Hypoid gears: 23/38. Oil capacity: 0.6 L of LW 80W-90. The e-coupling uses ECF107 ATF-based special oil, only 0.145 L. Operating temperatures -40 to 150°C for PTU, -40 to 120°C for e-coupling. Max torque on the e-coupling: 1,000 Nm. If your manual says something different, it’s aftermarket junk.

Don’t guess – use the factory sheet.

The manual starts with an overview of how the system shifts between AUTO and LOCK modes. Page 4 explains that in AUTO mode, the vehicle is normally in 2WD, and only engages the rear when traction is needed. LOCK mode gives highest traction, but automatically cancels above 40 km/h and resumes below 35 km/h. The system layout (page 5) shows the PTU, e-coupling, and control unit locations. You need this diagram to trace wiring before you start pulling components.

Specification Table: PTU and E-Coupling Data

Table on page 3 gives every important number: PTU weight 21.5 kg with oil, e-coupling weight 8 kg. Coil windings on the pilot clutch: 240 turns. Clutch counts – outer 11, inner 11 for main; outer 4, inner 3 for pilot. Without this data you can’t verify whether a salvaged unit matches the original spec. Aftermarket manuals skip this level of detail.

Overview and System Layout: Understanding the AWD Architecture

Section 1.1 covers the driving modes in depth. The 4WD LOCK switch logic page 4 is critical for diagnostics – if the customer reports the 4WD light turns off at highway speed, that’s normal. But if it doesn’t re-engage below 35 km/h, you have a control unit or speed sensor issue. The layout page 5 identifies each component location under the vehicle. Trust me, you want this before you start unbolting anything.

Removal and Installation: PTU Assembly and Oil Change

The oil change procedure on page 26 might look simple – drain, refill – but the manual specifies the exact fill level, the oil type (LW 80W-90 for PTU, ECF107 for e-coupling), and the torque for the drain plug. If you overtighten the plug on the e-coupling housing, you can crack the casing. I’ve seen that happen. The manual also tells you to check the oil condition for metal particles, which indicates internal damage. Skipping that step means you’ll install a new unit on a system that’s already chewing itself apart. That’s a comeback job you don’t want.

PTU assembly removal starts on page 16, disassembly on page 21. Each step has fastener sequence and torque values – the OCR doesn’t list them here but the manual does. For e-coupling assembly, go to page 28. Control unit removal is on page 36. If you need audio system wiring alongside this, check the SsangYong Korando 2010 Audio System Technical Manual.

3 Reasons OEM Documentation Beats Aftermarket Reprints

First, aftermarket manuals often compress multiple years into one, missing the 2010-specific updates like the 4WD lock logic change. Second, they skip the “Modification basis” note on page 2 that tells you which VIN ranges this applies to. Third, they use generic drawings. This OEM PDF is a scan of the original Ssangyong document – you get the exact layout, font, and part numbers. If you’re a shop owner, having this on a tablet next to the lift saves your techs from calling you every hour.

Does the Manual Cover the E-Coupling Control Unit?

Yes, section 3280-17 on page 12 covers the E-Coupling Control Unit components, and removal/installation on page 36. The control unit manages clutch engagement based on driving conditions. Without the factory diagnostic steps, you might replace the unit when a wiring issue is the root cause. The manual includes the system layout to help you test the circuit.

Frequently Asked Questions

What vehicles does this cover?

Only 2010 Korando AWD.

Is this manual for the entire car?

No, it focuses exclusively on the AWD system – PTU, e-coupling, control unit. Engine, transmission, brakes are not covered.

How do I know if my Korando’s 4WD lock mode is working correctly?

The manual describes the logic: LOCK mode is engaged when you press the switch, but if rear wheel speed exceeds 40 km/h, it automatically switches to AUTO mode and the indicator turns off. When speed drops below 35 km/h, it resumes LOCK mode and the indicator turns back on. This is critical for diagnosing why your 4WD light is behaving oddly. Many aftermarket sources omit this speed hysteresis detail. The manual page 4 provides the mode table.

What oil does the e-coupling use?

ECF107 ATF based EMCD special oil, capacity 0.145 L.
