Part of the Hyundai Repair Manuals.
Written for a single engine, the L4GC industrial unit, this Hyundai L4GC shop manual PDF runs 153 pages across general data, engine mechanical, engine electrical and fuel system chapters. Wiring diagrams cover the ignition, charging and starting systems, so you can trace each circuit. Mechanical work runs through the camshaft, HLA, timing chain, crankshaft, flywheel, pistons and connecting rods, then the cylinder head assembly and timing belt. Fuel system troubleshooting and injector service close it out. Fill with 4.0 L of oil including the filter, tighten the filter to 1.2 to 1.6 kg·m, and set spark plug clearance at 0.7 to 0.8 mm. Scheduled maintenance includes the drive belt check: 4.0 to 4.4 mm deflection on a new belt, 5.1 to 5.7 mm on a used one. Bookmarked and text-searchable, the file travels with you to wherever the L4GC is installed, tightening torque table and timing belt tension included.
