Essential Maintenance for Your honda civic 1987 si

Keeping your honda civic 1987 si in top shape requires a consistent maintenance schedule. Think of it as preventative medicine for your classic. Regular checks and timely replacements are key to avoiding costly breakdowns and extending its lifespan. This section focuses on a thorough honda civic 1987 si care guide.

Fluid Checks & Changes

Fluids are the lifeblood of your vehicle. Don’t overlook them.

Engine Oil: Change every 3,000-5,000 miles or every 6 months, using a good quality 10W-30 or 10W-40 oil. Always replace the oil filter (e.g., a Fram PH3593A or equivalent) with each change.
Transmission Fluid: For the manual gearbox, Honda recommends a specific manual transmission fluid (MTF). Change it every 30,000 miles. Don’t use standard gear oil, as it can damage the synchros.
Coolant: Flush and replace your engine coolant every 2-3 years, or every 30,000 miles. Use a silicate-free, ethylene glycol-based coolant. Make sure the system is properly bled of air afterwards to prevent overheating.
Brake Fluid: Bleed and replace your brake fluid every 2 years. Old brake fluid absorbs moisture, leading to a spongy pedal and reduced braking performance. Use DOT3 or DOT4 fluid.
Power Steering Fluid: Check the reservoir level regularly. If it looks dark or smells burnt, consider flushing and replacing it.

Always inspect hoses and belts for cracks or wear during fluid checks. A failing hose can lead to a rapid loss of fluid and potential engine damage.

Ignition System Health

A strong spark is crucial for performance and fuel efficiency. Here’s how to honda civic 1987 si ignition system maintenance:

Spark Plugs: Inspect and replace spark plugs (e.g., NGK BCPR6ES-11) every 30,000 miles or as needed. Look for signs of fouling or wear.
Distributor Cap & Rotor: These wear items can cause misfires. Replace them every 30,000-50,000 miles. Look for carbon tracking or excessive pitting.
Spark Plug Wires: Check for cracks or damage. If they’re original, consider replacing them with a quality aftermarket set for improved conductivity.
Ignition Coil: While less common, a failing ignition coil can cause intermittent misfires or a no-start condition. Test its resistance if you suspect an issue.

A well-maintained ignition system ensures smooth idling and optimal power delivery, which are benefits of honda civic 1987 si ownership.

Suspension & Steering Inspection

The Si’s handling is legendary. Keep it that way with regular checks.

Shocks/Struts: Look for leaks or excessive bounce. Worn shocks reduce handling and ride comfort.
Bushings: Inspect control arm bushings, sway bar bushings, and trailing arm bushings. Cracks or excessive play here will lead to sloppy handling and clunking noises. Polyurethane bushings are a popular upgrade for longevity and performance.
Tie Rod Ends & Ball Joints: Jack up the car and check for play. Grab the wheel at 12 and 6 o’clock (ball joints) and 3 and 9 o’clock (tie rods) and try to wiggle it. Any significant play means replacement is due.
Alignment: After any suspension component replacement, or if you notice uneven tire wear or the car pulling, get a wheel alignment.

Maintaining these components is crucial for the honda civic 1987 si‘s renowned agility and your safety.

Tackling Common Problems with Your honda civic 1987 si

Every classic car has its quirks, and the honda civic 1987 si is no exception. Knowing the common problems with honda civic 1987 si models can save you time, money, and frustration. Here’s a guide to some frequent issues and how to approach them.

Rust Prevention & Repair

Rust is the arch-nemesis of any vintage vehicle, especially those from regions with harsh winters. Early Civics are particularly susceptible.

Common Areas: Pay close attention to wheel arches, rocker panels, floor pans, the spare tire well, and around the windshield and rear window seals.
Prevention: Regularly wash your car, especially after driving on salted roads. Apply rust-proofing treatments (like Waxoyl or Fluid Film) to vulnerable areas, especially inside cavities.
Repair: For surface rust, sand it down to bare metal, apply a rust converter, primer, and paint. For more serious rust-through, cutting out the affected metal and welding in new patch panels is the only long-term solution. This might be a job for a professional body shop if you’re not experienced with welding.

Addressing rust early is a critical honda civic 1987 si best practice to preserve its structural integrity and value.

Electrical Gremlins

Older wiring can lead to mysterious electrical issues. Don’t let them scare you!

Fuses: Always start by checking the fuse box. A blown fuse is a common culprit for non-functioning accessories, lights, or even engine issues.
Ground Wires: Poor grounds are a frequent cause of intermittent electrical problems. Inspect main engine grounds, battery grounds, and chassis grounds for corrosion or looseness. Clean them thoroughly.
Corroded Connectors: Over time, moisture and dirt can corrode electrical connectors. Disconnect, inspect, and clean them with electrical contact cleaner. Dielectric grease can help prevent future corrosion.
Ignition Switch: A worn ignition switch can cause intermittent power loss or difficulty starting. If you notice flickering lights or power cutting out while driving, investigate this.

When diagnosing electrical issues, a multimeter is your best friend. Always disconnect the battery before working on electrical components to prevent accidental shorts.

Fuel System Quirks

Issues with the fuel system can lead to poor performance or no-start conditions.

Fuel Filter: A clogged fuel filter restricts fuel flow, causing hesitation or stalling. Replace it every 30,000 miles. It’s typically located along the fuel line near the firewall.
Fuel Pump: If your car cranks but doesn’t start, and you don’t hear the fuel pump prime when you turn the key, it might be failing. Listen for a distinct hum from the rear of the car when the ignition is turned to ‘ON’.
Fuel Injectors: Clogged or dirty injectors can cause misfires, rough idle, or reduced fuel economy. You can try fuel injector cleaner additives, or for more stubborn cases, professional ultrasonic cleaning.
Main Relay: This is a common failure point in older Hondas. A faulty main relay can prevent the fuel pump from activating, leading to a no-start or intermittent stalling issue. The symptoms often worsen in hot weather. It’s usually located under the dash.

Always exercise caution when working with fuel. Ensure adequate ventilation and have a fire extinguisher nearby.

Performance & Sustainable Upgrades for the honda civic 1987 si
