Section 1: Essential Engine Components and Maintenance
The heart of the 2018 Compass is its engine. Familiarizing yourself with its key components is essential for proper maintenance and troubleshooting.
- Engine Oil and Filter: The 2018 Compass typically uses a 2.4L Tigershark MultiAir 2 engine. Regular oil changes (every 5,000-7,500 miles depending on driving conditions) are crucial. Use the correct oil type (specified in your owner's manual) and a quality oil filter.
- How-To: Locate the oil drain plug and oil filter. Drain the old oil, replace the filter, and refill with fresh oil to the correct level.
- Considerations: Using the wrong oil viscosity can negatively impact engine performance and longevity.
- Air Filter: A clean air filter ensures proper airflow to the engine. Replace it every 12,000-15,000 miles, or more frequently in dusty conditions.
- How-To: Locate the air filter housing (usually under the hood). Remove the old filter and replace it with a new one.
- Considerations: A clogged air filter can reduce fuel efficiency and engine power.
- Spark Plugs: Spark plugs ignite the air-fuel mixture in the engine. Replace them according to the manufacturer's recommendations (typically every 30,000-50,000 miles).
- How-To: Remove the ignition coils, then use a spark plug socket to remove and replace the spark plugs.
- Considerations: Worn spark plugs can cause misfires, reduced fuel economy, and rough idling.
- Battery: The battery provides the necessary power to start the engine. Regular maintenance, such as cleaning the terminals, can prolong its lifespan.
- Considerations: Extreme temperatures can affect battery performance.
- Cooling System: The cooling system prevents the engine from overheating. Regularly check the coolant level and inspect hoses for leaks.
- Parts: Radiator, hoses, water pump, thermostat.
- Considerations: Overheating can cause severe engine damage.
Section 2: Brakes, Suspension, and Steering: Ensuring Safety and Control
These systems are critical for safe driving.
- Brake Pads and Rotors: Inspect brake pads regularly for wear. Replace them when they reach the minimum thickness. Rotors should be replaced or resurfaced if they are warped or excessively worn.
- How-To: Remove the wheel, caliper, and brake pads. Inspect the rotor. Replace pads and rotors as needed.
- Considerations: Worn brakes can significantly reduce stopping power.
- Suspension Components: The suspension system provides a comfortable ride and maintains stability. Common components include shocks, struts, springs, and control arms.
- Signs of Wear: Bouncing, excessive body roll, uneven tire wear.
- Parts: Shocks, struts, springs, control arms, ball joints, sway bar links.
- Steering System: The steering system allows you to control the direction of the vehicle. Check the power steering fluid level regularly and inspect for leaks.

- Infotainment System: The Uconnect system controls audio, navigation, and other features.
- Floor Mats: Protect the vehicle's carpet from dirt, mud, and wear.
Section 4: Transmission and Drivetrain: Powering the Wheels
This system transfers power from the engine to the wheels.
- Transmission Fluid: Regularly check and replace the transmission fluid according to the manufacturer's recommendations.
- Considerations: Using the wrong transmission fluid can damage the transmission.
- Driveshaft and Axles: These components transfer power from the transmission to the wheels.
- Signs of Wear: Vibrations, clicking noises.
- Transfer Case (4x4 Models): The transfer case allows you to switch between two-wheel drive and four-wheel drive.
- Considerations: Proper maintenance of the transfer case is essential for off-road performance.
Section 5: Choosing the Right Parts: OEM vs. Aftermarket vs. Used
When replacing parts, you have several options:
- OEM (Original Equipment Manufacturer): These parts are made by the same manufacturer that supplied the parts for the original vehicle. They offer the best fit and performance but are typically the most expensive.
- Aftermarket: These parts are made by third-party manufacturers. They can offer a lower price point but may vary in quality and fit. Research brands carefully before purchasing.
