- Fix: Replace the window motor and/or regulator assembly. It’s a common DIY job; just be careful with the glass.
Rust:
- Symptom: Bubbling paint, holes in body panels, especially rear wheel arches, rocker panels, and subframe.
- Common Culprits: Exposure to road salt and moisture.
- Fix: Early surface rust can be sanded and treated. Significant rust may require professional bodywork. Regular washing and waxing, especially in winter, can help prevent it.

Remember, when diagnosing, always start with the simplest and most common causes. Many issues can be resolved with basic hand tools and patience.

Performance & Off-Road Readiness: Upgrading Your 1999 Honda Civic EX Coupe

While the term “off-road readiness” might seem ambitious for a Civic, it’s all about enhancing durability, handling, and perhaps a slight edge for unpaved roads or spirited driving. These 1999 Honda Civic EX Coupe tips will help you make smart choices.

Engine Performance: Smart, Sustainable Gains

The D16Y8 engine is robust but not a powerhouse. Focus on efficiency and longevity rather than chasing huge horsepower numbers, which can compromise reliability.

Intake and Exhaust: A cold air intake (CAI) and a quality cat-back exhaust system can improve throttle response and add a few horsepower. Look for systems that maintain a good flow without being excessively loud. This can contribute to a more sustainable 1999 Honda Civic EX Coupe by improving breathing efficiency.
Engine Tuning: A custom ECU tune (e.g., Hondata S300 or similar) can optimize fuel and ignition timing for your specific modifications, yielding better power and potentially improved fuel economy. This is a great way to make your Civic more eco-friendly by optimizing its performance.
Maintenance for Power: Don’t forget that peak performance comes from a well-maintained engine. Clean fuel injectors, fresh spark plugs, and a healthy ignition system are paramount.

Suspension & Handling: Cornering with Confidence

This is where you can truly transform the driving experience of your Civic.

Coilover Suspension: A good set of coilovers (like Tein, Koni, or BC Racing) allows for adjustable ride height and dampening, dramatically improving handling. For rougher roads, you might consider a slightly taller, softer setup, but generally, Civics shine with a firmer, lower stance.
Sway Bars: Upgrading front and rear sway bars (e.g., ASR subframe brace with a larger rear sway bar) reduces body roll and sharpens turn-in.
Bushings: Replacing old rubber bushings with polyurethane alternatives (e.g., Energy Suspension) will tighten up the suspension feel, reduce deflection, and improve handling precision.

Brakes, Wheels & Tires: Grip and Stop

Stopping power and traction are crucial for any driving style.

Brake Upgrades: For better stopping power, consider upgrading to larger front rotors and calipers from an Acura Integra or Civic Si (if compatible with your EX). Performance pads (like Hawk HPS) and stainless steel brake lines also make a noticeable difference. Don’t forget to use fresh DOT4 brake fluid.
Wheels and Tires: Lighter wheels reduce unsprung weight, improving acceleration, braking, and handling. A good set of performance all-season or summer tires (e.g., Michelin Pilot Sport, Continental ExtremeContact) will dramatically improve grip. For light rough-road use, consider tires with a slightly more aggressive tread pattern and higher sidewall for compliance.

Always balance performance gains with the car’s intended use and your budget. Remember, even subtle, well-chosen modifications can significantly enhance your driving experience without compromising the reliability of your 1999 Honda Civic EX Coupe.

Buying a Used 1999 Honda Civic EX Coupe: Your Ultimate Guide

Looking to buy one of these legendary coupes? Smart move! But like any used car, it pays to know what to look for. This section is your essential 1999 Honda Civic EX Coupe guide for potential buyers.

What to Look For: Red Flags and Green Lights

Rust: This is the biggest enemy. Pay close attention to the rear wheel arches, rocker panels, subframe, and shock towers. Surface rust on suspension components is normal, but structural rust is a deal-breaker.
Engine:
- Listen for: Ticking (valve adjustment needed), knocking (serious internal issue), grinding (timing belt tensioner or accessory bearing).
- Check for: Oil leaks (valve cover, distributor, VTEC solenoid), excessive smoke from the exhaust (blue for oil, white for coolant, black for rich fuel mixture).
- Oil Dipstick: Check oil level and condition. Dark but not sludgy is okay. Milky or frothy indicates coolant in the oil (head gasket issue).
Transmission:
- Automatic: Look for smooth, timely shifts without harshness or slipping. Check the fluid – it should be reddish, not dark brown or burnt smelling.
- Manual: Test all gears. Clutch should engage smoothly, not too high or too low. Listen for grinding when shifting, which could indicate worn synchros.
Suspension: Push down on each corner of the car. It should rebound once or twice, not bounce excessively. Listen for clunks or squeaks over bumps during a test drive.
Interior: Check for excessive wear, especially on the driver’s seat. Ensure all lights, gauges, and accessories (windows, A/C, radio) work.

Pre-Purchase Inspection: Don’t Skip This Step

If you’re serious, consider a pre-purchase inspection (PPI) by a trusted mechanic, even if it costs a bit. They can put it on a lift and spot issues you might miss.

Test Drive Checklist: Feel It Out

A good test drive is crucial to understanding the car’s condition.

Cold Start: Insist on seeing the car started cold to identify any starting issues or smoke.
Engine Performance: Accelerate gently and firmly. Listen for unusual noises, feel for hesitation.
Brakes: Test emergency braking in a safe area. The car should stop straight without pulling. No grinding, squealing, or sponginess.
Steering: Does it feel tight or loose? Listen for groaning during full lock turns (power steering pump issue).
Suspension: Drive over bumps and uneven surfaces. Listen for clunks, rattles, or excessive bouncing.
Transmission: Pay close attention to shifts in both automatic and manual models.
Electrical: Test all windows, mirrors, radio, A/C, heater, and lights.

By following these guidelines, you’ll be well on your way to finding a gem of a 1999 Honda Civic EX Coupe that will serve you faithfully.

Safety First: Keeping Your Classic Civic Safe and Sound

Even though the 1999 Civic is an older car, you can take steps to ensure it remains as safe as possible on the road. Prioritizing safety is always a wise choice, especially for the everyday car owner and weekend DIYer.

Brake System Health: Regularly inspect brake pads, rotors, and calipers. Ensure brake fluid is clean and at the correct level, and bleed the system every two years. A firm pedal and responsive stopping are non-negotiable.
Tire Condition: Always maintain correct tire pressure and replace tires when tread depth is low or if they show signs of cracking. Proper tires are your only contact with the road.
Lighting: Check all exterior lights—headlights, taillights, turn signals, and brake lights—before every drive. Replace dim or burnt-out bulbs promptly. Consider upgrading to modern LED bulbs for improved visibility and longevity, especially for taillights.
Fluid Levels: Ensure all fluids (oil, coolant, power steering, brake) are at their proper levels. Low fluid can lead to system failures, impacting safety.
Seatbelts and Airbags: Confirm seatbelts are in good condition, retract properly, and latch securely. While airbags in older cars are not as advanced as modern systems, ensure the airbag warning light is not illuminated, indicating a fault.
Steering and Suspension: Any looseness, clunking, or excessive play in the steering or suspension components can compromise control. Address these issues immediately.

Never compromise on safety. If you’re unsure about a repair, it’s always best to consult a licensed professional. Your life, and the lives of others, depend on your vehicle being in safe operating condition.
