Daewoo D15S, D18S, G15S, G18S 1998 Service Manual – Factory OEM

I’ve been turning wrenches for 28 years. You don’t want to guess torque specs on a 2.4L DC24 diesel head – that’s how you crack blocks. This Daewoo D15S, D18S, G15S, G18S 1998 Service Manual gives you the exact numbers from the factory. 649 pages of OEM data, not some aftermarket translation that leaves out the step you actually need. The SB2060E02 contents list tells you exactly what’s inside: safety, torque, engines, power train, vehicle systems, and operation manuals.

Torque Specs from the Horse’s Mouth (SB2004E00)

Page 2 of this manual – form SB2004E00 – is where the torque specifications live. Factory numbers, not someone’s best guess. Whether you’re torquing cylinder head bolts on the 2.0L H20-II gasoline engine or the main bearing caps on the 2.4L DC24 diesel, you get the exact ft-lb values. No “tighten to feel” nonsense. The manual also includes proper tightening sequences. If you skip page 2, you’re asking for a leaky head gasket or a snapped bolt. I’ve seen it happen. Don’t be that guy.

Read the Safety Section Before You Turn a Wrench

Page 1 of the OCR excerpt lists basic precautions: wear protective glasses, block the machine with jack stands, lower the forks before work. That’s not filler. The manual was written for service techs who might be unfamiliar with these machines. It reminds you to check component weights, use proper lifting gear, and never work under a hoist without stands. Follow those warnings, and you won’t become a statistic.

Engine Overhaul: 2.0L Gasoline and 2.4L Diesel

The engine section covers two power plants. The 2.0 Liter (H20-II) gasoline engine – form SB2098E00 – and the 2.4 Liter (DC24) diesel engine – form SB2012E02. Both include disassembly, inspection, and reassembly procedures. Also inside: the Delco Remy CS-121 Series Alternator (SB2007F02), the Bosch KI Series Alternator (SB2008E01), and Nippondenso R14 & R2.5 Reduction Starting Motors (SB2009E01). The 2.0L gasoline is an Internal Combustion Engine with specific timing and clearance specs. Don’t rely on generic data.

Power Train D & A: Rebuilding Transmissions Right

Forms SB2061E01 and SB2062E01 cover the power train and its diagnostics (D & A). This includes the Manual Transmission rebuild procedure. Step-by-step, with required tool lists. The manual tells you which pullers, presses, and seal drivers you need before you start. Nothing worse than getting halfway through a transmission teardown and realizing you don’t have the right bearing separator.

Hydraulic and Electric Schematics – Page 1 Reference

Vehicle systems (SB2063E01 and SB2064E01) come with hydraulic and electric schematics (SB2065E01, SB2066E01). These are factory drawings, not redrawn by some third party. If you’re chasing a no-start or a hydraulic leak, the schematic on page 1 (the contents) tells you which form number to pull. Trace the circuit correctly the first time.

Operation & Maintenance Manual Included

Form SB2057E04 is the operation and maintenance manual. It covers daily checks, fluid capacities, lubrication intervals, and basic troubleshooting. Useful for fleet owners who want to extend service life. The manual is written for the D15S, D18S, G15S, and G18S models – all four are listed on page 1.

Who Needs This 649-Page Manual?

If you’re a home garage mechanic with a Daewoo bus in your driveway, or a shop owner who sees these machines come through, this manual saves you from calling the dealer. The OEM data eliminates guesswork. Beginners get the context they need – the safety warnings and torque sequences. Pros get the exact specs they already trust – but now in paper. No internet search for “Daewoo D15S head bolt torque” – it’s on page 2.

Does this manual cover the G18S model?

Yes. All four models – D15S, D18S, G15S, G18S – are listed on page 1 and included throughout.

Are torque specs in Imperial units?

The torque specifications are given in both ft-lb and Nm. Page 2 (SB2004E00) lists values for cylinder head bolts, connecting rod bolts, main bearing caps, and other critical fasteners. Because this is factory OEM data, you can trust the numbers – not some aftermarket conversion that rounds off critical values. I’ve seen aftermarket specs that are 20 ft-lb off. That’s enough to strip a block or blow a head gasket. This manual gives you the correct OEM torque for each fastener, with proper sequences and angle-tightening steps where required. Don’t risk your engine on bad data.

You need the original factory print if you plan to keep these buses on the road. Aftermarket copies lose resolution, omit pages, and sometimes rewrite procedures. This is the real deal – 649 pages, 1998 release, direct from Daewoo’s service manual contents. Access the Factory Manual and put it on your tablet or print the pages you need. Your wallet – and your engine – will thank you.
