These sourced values are shared by the specification sheet and the maintenance guides for this exact configuration.
- Engine oil viscosity
- SAE 5W-30 recommended for fuel economy; select climate-appropriate viscosity from the original chart. VerifiedOriginal 1991 manufacturer specification. Current replacement-product suitability or supersession has not been established.
- Engine oil specification
- API SG detergent oil; energy-conserving SG oil recommended. VerifiedOriginal 1991 manufacturer specification. Current replacement-product suitability or supersession has not been established.
- Engine oil refill with filter
- 3.7 US qt VerifiedRefill reference only; finish by the manual level-check procedure. A complete purchase set is not established.
- Coolant specification
- Honda-recommended antifreeze/coolant for aluminum engines; mix 50/50 with low-mineral or distilled water. Do not mix coolant types. VerifiedOriginal 1991 manufacturer specification. Current replacement-product suitability or supersession has not been established.
- Brake fluid
- DOT3 or DOT4 from a sealed container, following the reservoir-cap specification. Verified
- Automatic transmission fluid
- Original specification: DEXRON II automatic transmission fluid. VerifiedOriginal 1991 manufacturer specification. Current replacement-product suitability or supersession has not been established.
- Automatic transmission drain and refill
- 2.5 US qt VerifiedRefill reference only; finish by the manual level-check procedure. A complete purchase set is not established.
Automatic transmission fluid
Match the fluid to the exact transmission, not just the vehicle model. A drain-and-refill amount differs from the total dry capacity.
VerifiedBrake fluid and inspection
Check the reservoir and inspect any low level, warning light or changed pedal feel before driving. Repeated topping-up is not a repair.
VerifiedEngine air filter
The original replacement interval is recorded; exact filter fitment remains unverified.
VerifiedEngine coolant
Check the reservoir level with the engine cold and investigate repeated coolant loss. Coolant type and replacement procedure matter as much as capacity.
VerifiedSpark plugs
The original replacement interval is recorded; plug part number, gap and torque remain unverified.
VerifiedTiming belt and water-pump inspection
Track belt replacement by both age and mileage. This is an engine-specific workshop job, not a generic belt replacement procedure.
VerifiedTire inspection and rotation
Inspect tires and use the matching original rotation pattern. Pressure, size and wheel-torque applications remain unresolved.
