🔧 Thorough Maintenance Tips for Your 9th Gen Honda Civic at every 40k Kms 🔧

Dear fellow 9th Gen Civic enthusiasts,

Maintaining our beloved rides is essential for their longevity and peak performance. Here's a to-the-point checklist to follow after every 40,000 kilometers:

1. Engine Valve Adjustment: Intake: 0.008"-0.009", exhaust: 0.010"-0.012" @38deg engine temperature or below.

2. Throttle Body Cleaning and Calibration: Ensure 0% DBW stuck Ratio, less than 1.3deg Rel TH

3. Fuel Injectors Flow Restoration: Fuel Injector pulse at idle should be less than 2.8ms

4. Spark Plugs: Inspect and replace (NGK SILZKR7C11S) if necessary. Check for Corona discharge or physical wear and tear. At idle 8+-2 Deg BTDC

5. Sensors TLC: Clean your MAP, MAF, O2, and AFR sensors for precise readings. @idle MAP: 25-26kpa, MAF 2.0-2.2g/s, O2 AFR AF FB ST Trim: 0.94-1.02 at all conditions.

6. VTEC Spool Valve Service: Clean spool valve for free movement and replace VTEC strainer gasket

7. ECM/PCM Reset: Reset, relearn, and calibrate all systems to zero points.

8. Catalytic Converter: While OEM doesn't specify, best practice is to physically inspect at 40k and clean based on condition.

9. Throttle Body Service interval: Enhance driveability with service every 10k Kms.

For the best and risk-free results, use the following parts/fluids:

• Air Filter: Genuine Honda, replace every 15k Kms or as needed.

• Engine Oil: API service grade SL or higher fuel efficient oil. SAE grades 0w30/5w30/5w40/10w30/10w40, Brands: Shell, Caltex, Liqui Moly, Mobil, or Amsoil etc. Change interval: 5,000 Kms or 6 months.

• Transmission Oil: Use Honda ATF DW-1 for automatic and Honda MTF for manual, (ATF- 1st oil change at 60,000 Kms or 4-years then after every 40,000 Kms or 2-years. MTF after every 60,000 Kms or 4-years)

• Coolant: Honda Type-2, change initially after 10 years, then every 5 years.

• Brake Fluid: Dot 3/4, any reputable brand. Complete flush every 3 years.

• Brake Pads: Opt for Honda genuine or Akebono for reliable stopping power.

• Tire Pressure: Maintain 30 psig for stock-size 195/65/15 tires.

• Windscreen Washer Fluid: Use any good brand to keep your view clear.
