Expert-verified. Personally reviewed and approved by OLP's master technicians (Chris Hackleman & Jeff Moore — 20+ years each). Always follow the vehicle's factory service information and torque specs.

Complete 30,000 mile scheduled maintenance including engine oil and filter change, tire rotation, and multi-point inspection per Honda maintenance schedule.

Warnings

⚠️Never work under a vehicle supported only by a jack. Always use jack stands rated for the vehicle weight.
Ensure engine is cool before starting oil change to prevent burns from hot oil and components.
Used engine oil contains harmful contaminants. Avoid prolonged skin contact and dispose of properly at a recycling facility.
ℹ️This procedure covers the standard 30K service. Refer to owner's manual for additional items if operating under severe conditions.

Parts

  • Engine oil filter × 1 — Honda 15400-PLM-A02 or equivalent
  • Oil drain plug crush washer × 1 — Honda 94109-14000 or equivalent
  • Engine air filter × 1 — Honda 17220-5AA-A00 or equivalent
  • Cabin air filter × 1 — Honda 80292-TBA-A11 or equivalent

Fluids

  • Honda Genuine 0W-20 engine oil — 4 qt
  • Windshield washer fluid — 3.5 qt

Preparation

  1. Park vehicle on level surface and engage parking brake
  2. Allow engine to cool for at least 30 minutes if recently driven
  3. Gather all tools, parts, and fluids before starting
  4. Verify replacement parts match OEM specifications for this engine
  5. Prepare workspace with adequate lighting and ventilation

Procedure

  1. 1
    Raise and secure vehicle
    Loosen all wheel lug nuts by 1 turn while vehicle is on ground. Raise vehicle using floor jack at designated front and rear jacking points. Place jack stands under recommended support points on both sides. Lower vehicle onto jack stands and verify stability before working underneath.
  2. 2
    Remove wheels and inspect brakes
    Remove all four wheels completely. Visually inspect brake pads through caliper opening for remaining thickness (minimum 3mm). Check brake rotors for scoring, excessive rust, or warping. Inspect brake lines and hoses for cracks, leaks, or damage. Record pad thickness percentages for maintenance records.
  3. 3
    Drain engine oil
    Position drain pan under oil drain plug located on passenger side of oil pan. Using 19mm socket, loosen drain plug slowly. Remove plug by hand for final turns, allowing oil to drain completely. Inspect drain plug threads and oil pan threads for damage. Remove and discard old crush washer from drain plug. Allow minimum 10 minutes for complete drainage.
    Oil may still be warm. Drain plug will release suddenly when threads clear - keep hands clear of oil stream.
  4. 4
    Remove oil filter
    Locate oil filter on front of engine block below exhaust manifold. Position drain pan beneath filter. Using oil filter wrench, turn filter counterclockwise to remove. Expect residual oil spillage (approximately 0.25 quart). Verify old filter gasket came off with filter and is not stuck to engine block mounting surface. Clean mounting surface with lint-free cloth.
  5. 5
    Install new oil filter
    Apply thin film of clean engine oil to new filter gasket using finger. Thread new filter onto mounting boss by hand only - do not use filter wrench for installation. Tighten filter until gasket contacts mounting surface, then rotate an additional 3/4 turn by hand. Verify filter is secure but do not over-tighten.
  6. 6
    Install drain plug with new washer
    Install new crush washer onto drain plug. Thread drain plug into oil pan by hand to avoid cross-threading. Using 19mm socket and torque wrench, tighten drain plug to specification. Verify plug is secure and washer is properly compressed.
  7. 7
    Fill engine with new oil
    Lower vehicle enough to access engine bay safely or work from above. Remove oil fill cap on top of engine (marked with oil can symbol). Insert funnel and add 3.5 quarts of Honda Genuine 0W-20 oil initially. Wait 2 minutes for oil to settle, then check dipstick. Add remaining oil in 0.25 quart increments until level reaches upper mark on dipstick. Total capacity is 4.0 quarts including filter. Install oil fill cap securely.
  8. 8
    Replace engine air filter
    Open hood and locate air filter housing on driver side of engine bay. Release air box clips securing top cover. Lift cover and remove old engine air filter. Inspect housing interior for debris, leaves, or moisture - clean if necessary. Install new air filter ensuring directional arrows (if present) point toward engine. Secure housing cover and engage all clips.
  9. 9
    Replace cabin air filter
    Open glove box and remove contents. Press sides of glove box inward to release stops and lower fully. Locate cabin air filter access door behind glove box. Press tabs to remove cover. Slide out old cabin air filter, noting installation direction (airflow arrows). Install new cabin air filter with arrows pointing in same direction as original. Reinstall access cover and glove box.
  10. 10
    Perform underbody inspection
    With vehicle still raised, inspect entire underbody systematically. Check for oil leaks at drain plug, oil filter, valve cover, and front main seal. Inspect CV boot condition for tears or grease leakage. Check exhaust system hangers and look for excessive corrosion or damage. Examine suspension components for leaking shocks, worn bushings, or damaged control arms. Inspect fuel lines and brake lines for corrosion or damage.
  11. 11
    Rotate tires
    For this FWD vehicle, perform front-to-rear tire rotation: move front wheels straight to rear on same side, move rear wheels straight to front on same side. If tires are directional, they must stay on same side. If non-directional, consider cross-rotation pattern per tire manufacturer recommendations. Clean wheel mounting surfaces on hubs before reinstalling wheels.
  12. 12
    Reinstall wheels and lower vehicle
    Install wheels in new positions, threading lug nuts by hand first to avoid cross-threading. Using torque wrench and star pattern, tighten lug nuts to specification in three stages: first to 50 Nm, second to 100 Nm, final to 140 Nm. Raise vehicle slightly off jack stands, remove stands, and lower vehicle completely to ground. Perform final torque verification of all lug nuts in star pattern with vehicle weight on wheels.
  13. 13
    Start engine and verify operation
    Start engine and allow to idle. Monitor oil pressure light - it should extinguish within 2-3 seconds. Check for oil leaks at drain plug and filter while engine runs. Let engine reach normal operating temperature (approximately 5 minutes). Shut off engine and wait 2 minutes. Recheck oil level on dipstick and add if necessary to reach upper mark. Verify no leaks are present.
  14. 14
    Check and adjust tire pressures
    Check tire pressure in all four tires plus spare using tire pressure gauge. Refer to door jamb sticker for correct pressures (typically 32-33 PSI front and rear for this model, but verify on your specific vehicle). Adjust as needed. Check tire tread depth using tread wear indicators or depth gauge - minimum legal depth is 2/32 inch but replace at 4/32 inch for safety.
  15. 15
    Top off washer fluid and complete inspection
    Check windshield washer fluid reservoir and fill to maximum line with fresh fluid (approximately 3.5 quart capacity). Check coolant level in overflow tank - should be between MIN and MAX marks when cold; add Honda Type 2 (Blue) coolant if low. Verify brake fluid level in master cylinder reservoir is between MIN and MAX marks. Check power steering operation (electric system, no fluid check needed). Test all exterior lights and windshield wipers. Reset maintenance reminder in instrument cluster if equipped.

Reassembly

  1. Ensure oil fill cap is securely tightened
  2. Verify air filter housing cover is properly latched with all clips engaged
  3. Confirm all wheels are torqued to specification in star pattern
  4. Double-check that no tools or materials were left in engine bay or under vehicle

Verification

  • Start engine and verify oil pressure warning light extinguishes immediately and no unusual noises are present
  • Inspect ground under vehicle after running engine - confirm no oil, coolant, or fluid leaks
  • Verify oil level on dipstick reads at upper mark with engine off and cooled for 2+ minutes
  • Test drive vehicle 5-10 miles, then recheck oil level and inspect for leaks once more
  • Confirm maintenance reminder light has been reset if applicable
  • All warning lights should function normally during startup and extinguish after engine starts
  • Document service with date, mileage, and any observations in vehicle maintenance log
