Daewoo D15S-2, D18S-2, D20SC-2, G15S-2, G18S-2 2000 Service Manual

I’ve been turning wrenches since before most of you were born, and I can tell you right now: if you’re working on a Daewoo D15S-2, D18S-2, D20SC-2, G15S-2, G18S-2 2000 Service Manual, you need factory data. Not some aftermarket reprint that guesses torque values. This is the actual OEM binder that came off the line in October 2000 – 563 pages of tightly organized procedures that cover every system from the G420 LP/gasoline engine to the DC24 diesel, plus the CS-121 and CS-105D alternators. The TOC alone lists 30+ chapters, and I’m going to walk you through the ones that matter most.

Crankshaft And Cylinder Block: Factory Removal Procedure

You’ll find the removal and installation section inside SB4008E01. It starts with the Crankshaft And Cylinder Block chapter – not buried in an appendix. The manual tells you the exact sequence for pulling the block without warping the deck. Torque specs for main bearing caps are listed in that same section. Need the charge pressure? Page 73. Don’t guess. The manual also covers Cylinder Head And Valves, Piston And Connecting Rod, and Rocker Arms And Camshaft. Every bolt pattern, every tightening angle is there because the engineers tested it.

What Torque Specs Are Listed?

The manual has a dedicated Torque Specifications page (SB2004E00, Dec. 1998) that gives fastener torque in ft-lb for every major joint: cylinder head bolts, connecting rod nuts, flywheel bolts, and the timing belt tensioner. Miss that and you’ll have a head gasket leak inside 50 hours. I’ve seen it happen. The Sealant section in General Information also tells you which thread locker to use on which bolt – Loctite types, not generics. That’s the difference between a one-time job and a comeback.

563 Pages of OEM Data

Why 563 pages? Because they didn’t skip anything. You get the whole powertrain section – Torque Converter, Transmission, Differential And Drive Axles from SB4018E01. The Transmission Hydraulic System chapter includes converter stall test procedure and pinion depth check. The Transmission Pressure Tests tell you exactly what PSI you need at each port. That’s not in any generic manual. Also included: vehicle systems sections on brakes, steering, and mast hydraulics from SB4019E01 and SB4020E01. Every hose routing and adjustment spec is original.

Alternator Diagnostics: CS-121 and CS-105D

Two alternator sections are in this manual – one for the Delco Remy TS-121 Series and one for the CS-150D (which is essentially the CS-105D). The SB2007E01 and SB4050E00 both cover Alternator Output Test and Machine Test. The wiring schematics show each terminal with voltage drop tolerances. If your battery light flickers and the charge lamp stays on, you run that machine test first – it isolates the regulator from the rectifier without pulling the unit. That alone saves you an hour of guesswork. For reference, the Internal Combustion Engine section of the manual explains the entire engine system operation, including the fuel and lubrication circuits.

Get the Right Fuel System Info

The Fuel System chapter under Removal And Installation covers carburetor removal on the LP/gas engines and injection pump timing on the diesel. The System Operation section then gives you the fuel flow diagram with pressure curves. If you’re dealing with a lean stumble, you go to the Engine Adjustment chapter and find the idle mixture screw turns – factory spec, not a guess. Torque for the carburetor mounting nuts is listed right next to the air governor adjustment. And the Special Tools list tells you which pullers and adapters you need so you don’t hammer a tool in and crack a casting.

Source Validity: Why This Beats Aftermarket Copies

Every page in this scan comes from the original Daewoo binder form SB4047E. The watermark, the part numbers, the diagrams – all unaltered. Aftermarket manuals often crop out the torque page or renumber the figures. This one has the original October 2000 publication date and the complete TOC with form numbers SB4008E01, SB2012E02, SB2007E01, and SB4050E00. You get the Safety section that warns about jack stands, protective glasses, and proper lifting procedures. That’s not fluff – that’s liability insurance. If you’re training a junior tech, you hand them this manual and tell them to read the precautions first.

Related manuals you might need for the same era: DAEWOO Service Manual Contents SB4049E01, Daewoo Musso Service Manual – Factory OEM Specs for 1465-Page Workbench, and Daewoo 661LA, 662NA, 662LA 2000 Service Manual – Factory OEM. For drivetrain specifics, the Manual Transmission basics are covered in the powertrain section, but the factory manual gives you the exact clutch pack assembly and control valve disassembly steps.

Does this manual cover the G20SC-2 model?

The title lists G15S-2 and G18S-2. The G20SC-2 is referenced in the OCR as a model line, but the TOC doesn’t include a dedicated section for it. You’ll get the same engine and drivetrain specs since it shares the G-series platform, but confirm by checking the wiring schematics for your specific serial number.

Are the torque specs in ft-lb or Nm?

Imperial. All torque values are given in ft-lb. The specifications page (SB2004E00) uses foot-pounds. If you’re working with a metric wrench, you’ll need to convert – but the manual itself stays in imperial for the North American market.

Bottom line: this is the binder you want on your workbench when a customer’s forklift won’t start or leaks oil from every seal. The procedures are step-by-step, the torque values are verified, and the troubleshooting trees actually match the symptoms. Stop chasing ghosts. Access the Factory Manual and start with the section that matches your issue – the time you save pays for the purchase in one repair cycle.
