Manual Contents and System Overview
This 1989 Nissan service manual is organized into logical, system-specific sections that isolate necessary repair data. The manual begins with general vehicle identification, lifting points, and standard maintenance schedules for the Z24i and VG30i engines. Subsequent chapters outline the exact mechanical disassembly and assembly sequences for cylinder heads, timing systems, and oil pans. You will also find extensive chassis and body maintenance segments detailing the steering, suspension, brake systems, and transmission components.
Please note that while this manual provides exact factory specifications, you must always ensure your vehicle is properly secured on rated jack stands and observe standard shop safety protocols before initiating any heavy diagnostic or repair work.
The contents of this OEM service publication feature precise lubricant viscosity charts and fluid capacity requirements for the manual transmission, transfer case, and differential carriers. Electrical systems are thoroughly mapped out, including clear symbol keys and terminal arrangements.

The technical data sections deliver exact clearance values and torque settings required for shop-floor accuracy. For example, the engine maintenance chapters define Z24i valve clearances at 0.30 mm for both intake and exhaust. Engine oil capacity for the 4WD VG30i model is listed at 3.4 liters (3 5/8 US qt). Additionally, the front wheel bearing preload for 4WD models requires a starting force of 0.5–1.5 N-m after the initial tightening sequence. Quick-reference tables offer straightforward guidance for standard bolt tightening based on grade and diameter.
