These sourced values are shared by the specification sheet and the maintenance guides for this exact configuration.
- Engine oil viscosity
- SAE 5W-30 preferred; SAE 10W-30 only when temperature stays above 20°F (-7°C) Verified
- Engine oil specification
- API SJ Energy Conserving VerifiedSynthetic oil must meet the same classification; it does not extend the maintenance interval.
- Engine oil refill with filter
- 3.5 US qt VerifiedHX change quantity with filter; excludes oil remaining in the engine. The 3.7 L dry total is different. Check the dipstick after the prescribed settling period.
- Engine oil refill without filter
- 3.2 US qt VerifiedHX oil change without filter; not the dry total.
- Oil drain plug torque
- 29 lb-ft VerifiedHX/EX specification only; fit one new drain washer at every drain. The DX torque is different.
- Coolant specification
- Genuine Honda Antifreeze/Coolant, 50% coolant and 50% water VerifiedA major-brand non-silicate coolant for aluminum engines is a temporary substitute only. This evidence does not establish Type 2 backward compatibility.
- Brake fluid
- Genuine Honda DOT 3 brake fluid VerifiedOther sealed DOT 3 or DOT 4 is temporary only; flush and replace with Honda fluid as soon as possible. Never use DOT 5.
- Power steering fluid
- Genuine Honda Power Steering Fluid VerifiedOther power-steering fluid is emergency-only; do not use automatic-transmission fluid.
- Spark plug specification
- NGK ZFR4F-11 or DENSO KJ14CR-L11 VerifiedHX-specific application; the adjacent DX/EX plug row does not apply.
- Spark plug gap
- 0.043 in VerifiedNominal gap; follow the original plug instructions and tolerance.
- CVT fluid specification
- Genuine Honda CVT Fluid VerifiedThis 1998 specification does not approve HCF-2, DW-1 or conventional ATF.
- Engine coolant capacity
- 3.4 US qt VerifiedOwner-table change figure includes the 0.4 L reserve and coolant remaining in the engine. Do not treat the dry total as a refill or buying quantity.

Brake 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.
VerifiedCVT fluid
Match the fluid to the exact transmission, not just the vehicle model. A drain-and-refill amount differs from the total dry capacity.
VerifiedEngine air filter
Inspect the filter housing and replace the element on the applicable schedule, sooner in dusty use when the manual requires it.
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
Use the engine-specific plug type. Check the service schedule and inspect ignition faults before replacing parts.
VerifiedTires and rotation
Check cold pressures, tread wear and damage. Use the vehicle placard for the fitted tire size and load rather than the tire sidewall maximum.
VerifiedWiper blades and washer fluid
Replace damaged or streaking blades after checking that the glass and rubber are clean. Confirm the driver/passenger lengths and connector before ordering.
