Routine Checks You Can Do: How to 2020 Honda Civic EX Basics
Many essential checks don’t require a professional mechanic. With a few basic tools and a little know-how, you can monitor your Civic’s health.
- Tire Pressure: Check your tire pressure weekly, or at least bi-weekly. Look for the recommended pressure on the sticker inside your driver’s side door jamb. Under-inflated tires wear unevenly and reduce fuel economy. You’ll need a simple tire pressure gauge for this.
- Fluid Levels: Regularly check your engine oil, coolant, brake fluid, and windshield washer fluid.
- For engine oil, pull the dipstick, wipe it clean, reinsert it fully, then pull it out again to check the level. Ensure it’s between the “min” and “max” marks.
- Coolant should be checked in the overflow reservoir when the engine is cool.
- Brake fluid and power steering fluid (if applicable, though many modern Civics are electric) have clear reservoirs with “min” and “max” lines.
- Lights: Walk around your car and check all exterior lights – headlights (low and high beam), tail lights, brake lights, turn signals, and license plate lights. It’s a simple safety check.
- Wiper Blades: Inspect your wiper blades for cracks, tears, or hardening. Replace them annually, or sooner if they start streaking. Good visibility is non-negotiable.
Fluid Management: Oil, Coolant, and More
Fluids are the lifeblood of your Civic. Staying on top of their condition is crucial for longevity.
Engine Oil: Your 2020 Civic EX likely uses synthetic oil, typically 0W-20. Honda’s Maintenance Minder system will tell you exactly when an oil change is due, usually every 7,500-10,000 miles, or annually, whichever comes first. Don’t stretch these intervals. When changing oil yourself, you’ll need a drain pan, a wrench for the drain plug, an oil filter wrench, and a new oil filter (e.g., a Honda OEM filter or a high-quality aftermarket equivalent like a Mobil 1 or K&N filter). Always use the correct oil viscosity specified in your owner’s manual.
Coolant: Honda typically uses a blue, long-life coolant. Check the level in the overflow reservoir regularly. If it’s consistently low, you might have a leak, which needs immediate attention. The coolant should be flushed and replaced according to Honda’s schedule, usually every 5 years or 60,000 miles, but refer to your owner’s manual for precise intervals. Never open the radiator cap when the engine is hot!
Brake Fluid: This hygroscopic fluid absorbs moisture over time, which can lead to a spongy pedal and reduced braking performance. Honda recommends replacing brake fluid every 3 years or 45,000 miles. This is a job that many DIYers can tackle with a friend for bleeding, using a brake fluid bleeder kit and fresh DOT3 or DOT4 fluid as specified.
Transmission Fluid: For your CVT, transmission fluid changes are critical. Consult your owner’s manual or the Maintenance Minder system. Honda recommends using only genuine Honda HCF-2 CVT fluid. This isn’t a simple drain-and-fill like engine oil; proper procedure often involves multiple drain and fills to fully refresh the fluid. If you’re unsure, this is one to consider leaving to a professional.
Tire Health & Rotation
Your tires are the only contact points between your Civic and the road. Their condition directly impacts safety, handling, and fuel economy.
- Rotation: Rotate your tires every 5,000-7,500 miles. This promotes even wear across all four tires, extending their lifespan. You can do this with a floor jack and jack stands, following the rotation pattern in your owner’s manual (usually front-to-back for non-directional tires).
- Tread Depth: Use a penny to check tread depth. If Lincoln’s head is fully visible, it’s time for new tires. Worn tires significantly reduce grip, especially in wet conditions.
- Alignment: If you notice uneven tire wear, pulling to one side, or a crooked steering wheel, your alignment might be off. This requires a professional alignment shop.
Brake System Inspection
Reliable brakes are paramount for safety. You should inspect your brake system at least once a year, or every oil change.
Look for:
- Pad Wear: Visually inspect your brake pads through the wheel spokes. If the friction material is less than 3mm thick, it’s time for replacement. You might also hear a squealing sound from the wear indicators.
- Rotor Condition: Check the brake rotors for deep grooves, warping (which causes pulsation when braking), or rust. Minor surface rust is normal, but heavy pitting indicates replacement is needed.
- Brake Fluid Level: As mentioned, keep an eye on the reservoir. A dropping level without a leak could indicate worn pads.
Replacing brake pads and rotors is a common DIY job, requiring a jack, jack stands, a C-clamp (or brake caliper piston compressor tool), and appropriate wrenches. Always replace pads and rotors in pairs (both front or both rear) for even braking.
Troubleshooting Common Problems with Your 2020 Honda Civic EX
Even a reliable car like the Civic can develop issues. Knowing how to diagnose or at least describe potential common problems with the 2020 Honda Civic EX will save you time and money.
Electrical Gremlins & Warning Lights
Modern cars are packed with electronics, and sometimes things go awry.
- Check Engine Light (CEL): This is the most common and often most ambiguous warning light. It can indicate anything from a loose gas cap to a failing sensor (like an O2 sensor or mass airflow sensor). Your first step is to check the gas cap. If the light persists, a diagnostic scanner (OBD-II scanner) is your best friend. These can be purchased affordably online or at auto parts stores. The code it pulls will give you a starting point for diagnosis.
- Battery Issues: If your car struggles to start, or you notice dim lights, your 12V battery might be failing. Batteries typically last 3-5 years. You can check the battery voltage with a multimeter (should be around 12.6V when off, 13.7-14.7V when running). Replacing a car battery is a straightforward DIY task.
- Infotainment System Glitches: Occasionally, the touchscreen might freeze or act erratically. Often, a simple “reboot” (turn the car off and on, or hold the power button on the head unit for 10-15 seconds) can resolve this. Check for software updates from Honda if issues persist.
Suspension & Steering Concerns
Your Civic’s suspension provides a comfortable ride and responsive handling. Pay attention to changes in how it feels.
- Noises Over Bumps: Clunking, rattling, or squeaking noises when going over bumps can indicate worn suspension components like sway bar links, bushings, or strut mounts. Visually inspect these components for cracks or excessive play.
- Uneven Ride Height: If one corner of your Civic sits lower than the others, it could point to a failing spring or strut.
- Loose Steering: Excessive play in the steering wheel or a general feeling of looseness can suggest issues with tie rods, ball joints, or steering rack components. This is a safety concern and should be addressed promptly.
Powertrain & Transmission Notes
The 1.5L turbo engine and CVT are generally robust, but some specific points are worth noting.
- Turbo Lag/Hesitation: While the 1.5L turbo is responsive, a slight hesitation on acceleration (often called “turbo lag”) is normal. However, if it feels excessive or inconsistent, it could point to issues with the turbocharger, wastegate, or associated sensors.
- CVT Behavior: The CVT can feel different from a traditional automatic. A slight “rubber band” effect (where RPMs rise and stay high during acceleration) is normal. However, if you experience jerking, slipping, or unusual noises, especially during acceleration, it could indicate a CVT problem. Regular fluid changes are your best defense here.
- Oil Dilution (Earlier Models): Some early 1.5L turbo engines (specifically 2016-2018 models) experienced issues with fuel diluting the engine oil, especially in colder climates or with short trips. While largely addressed by 2020, it’s worth being aware of. If you smell gasoline in your oil or notice the oil level increasing, consult a Honda dealer.
When to Call a Pro
While DIY is great, some problems require specialized tools, deep diagnostic knowledge, or are simply too critical for an amateur. Always err on the side of caution.
- Persistent Warning Lights: If a check engine light or any other critical warning light (like brake, oil pressure, or battery) stays on after basic checks, it’s time for a professional diagnosis.
- Brake System Malfunctions: Any significant change in braking performance – soft pedal, grinding noises, pulling to one side – warrants immediate professional attention. Your life, and others’, depends on it.
- Transmission Issues: CVT problems can be complex and expensive. If you suspect a transmission issue, a Honda specialist or reputable transmission shop is your best bet.
- Complex Engine Noises: Ticking, knocking, or grinding noises from the engine are usually signs of serious internal issues. Don’t ignore them.
- Airbag or SRS System Warnings: These systems are critical safety components. Do not attempt to diagnose or repair them yourself.
