These sourced values are shared by the specification sheet and the maintenance guides for this exact configuration.
- Engine oil viscosity
- SAE5W-30 preferred;10W-30 only when ambient never falls below20°F(-7°C). Verified
- Engine oil specification
- Original1992 requirement: premium detergent oil, API ServiceSG; Energy ConservingII recommended. VerifiedHistorical factory specification; a current product must separately verify backward compatibility. Do not add oil additives.
- Oil drain plug torque
- 30 lb-ft Verified
- Coolant specification
- Original manual: genuine Honda Antifreeze/Coolant mixed50:50 with purified or distilled water; no additives. VerifiedDo not dilute a ready-mixed modern coolant. Current replacement-product compatibility must be checked separately; never open a hot system.
- Brake fluid
- Genuine Honda Brake Fluid or equivalent DOT3/DOT4; DOT5 prohibited. Verified
- Power steering fluid
- Genuine Honda power-steering fluid only; do not use ATF or another fluid type. Verified
- Spark plug gap

- Engine oil refill with filter
- 4.5 US qt VerifiedOil-change quantity including a new filter; excludes oil remaining in engine. Verify final dipstick level; not dry fill.
- Engine oil refill without filter
- 4.2 US qt VerifiedFactory change quantity without changing filter; not dry fill.
- Engine coolant capacity
- 7.7 US qt VerifiedFactory TOTAL cooling-system reference7.3L. The same table distinguishes CHANGE3.7L and footnote*1 includes reserve-tank/engine-retained coolant. Do not treat total as a routine refill or purchase quantity; follow printed140–143 procedure.
- Automatic transmission drain and refill
- 2.5 US qt VerifiedCHANGE quantity only; total6.0L differs. Confirm exact current Honda fluid supersession before purchase; the original1992 formulation is retained in provenance only.
- Spark plug specification
- Normal:NGK ZFR6F-11 / Nippondenso KJ20CR-L11. Hot climates or continuous high-speed driving:NGK ZFR7F-11 / Nippondenso KJ22CR-L11. Verified

12-volt battery
Exact case size,terminal layout,CCA and current replacement remain unverified; original55Ah/5-hour rating is not a replacement-fitment proof.
VerifiedAutomatic transmission fluid
Use the factory level-check procedure on level ground. Current replacement-fluid compatibility remains a required unresolved purchase item.
VerifiedBrake fluid and inspection
Brake-disc/caliper and rear-pad inspection is normally15,000mi/24,000km or12months; short trips,dust,salt/corrosives,rough/muddy roads or towing shorten it to7,500mi/12,000km or6months. ABS servicing applies only if equipped.
VerifiedEngine air filter
The original housing has four retaining clips. Clean opposite normal airflow as the manual describes; exact replacement-filter part remains unverified.
VerifiedEngine coolant
Follow the exact cold-engine drain,engine-block drain,bleed and warm-up procedure on printed140–143. Total capacity and change quantity differ.
VerifiedLights and fuses
Use the vehicle fuse labels. Printed bulb power/candlepower alone does not prove a modern replacement base or LED compatibility.
VerifiedScheduled chassis and owner inspections
Power-steering system inspection normally15,000mi/24,000km or12months; dust,severe cold or rough/muddy roads:7,500mi/12,000km or6months. Fuel filter may need earlier replacement after contaminated fuel; qualified technician required.4WS-specific work remains conditional.
VerifiedSpark plugs
Use the correct normal/hot-driving plug branch. Four plugs;16mm socket;1.1mm gap and18Nm tightening for the specified original plugs.
VerifiedTiming belt and water-pump inspection
Factory schedule only. Exact belt/tensioner/water-pump parts,torques and full workshop procedure remain required before ordering or work.
VerifiedTires and rotation
Keep original size,load and speed specification unless a separately verified replacement applies. The printed rotation pattern moves tires front-to-rear on the same side.
VerifiedWiper blades and washer fluid
Replace cracked,hardened or ineffective rubber. Use washer fluid; do not use engine antifreeze. Exact blade sizes/adapters are unverified.
