About the Ford Focus ST

Focus ST owners know that while performance is a priority, regular maintenance is key to prolonging the joy of driving. Key areas to monitor include:
• Driveline: If you've tuned your vehicle for increased power, it's crucial to pay attention to clutch maintenance, particularly regarding the clutch slave cylinder. Regular checks can prevent bigger issues down the line, especially if you're hitting service intervals around 80,000-150,000 km.
• Suspension: Worn suspension components can drastically affect the handling. Inspect sway bar sets, strut mounts, and control arm bushes as they wear over time, ensuring your ride quality remains sharp.
• Cooling System: Be vigilant about the engine’s temperature, especially after 150,000 km. Key parts like the water pump, thermostat, and radiator hoses should be checked to prevent overheating and ensure optimal performance. [This naturally links to /shop/cooling]
• Braking: Adequate stopping power is fundamental. Inspect your disc brake rotors regularly, as well as brake pads, to maintain safety.
• Spark Plugs: Keep spark plugs in line with service schedules to optimize engine performance - it's a small effort for significant improvements.
• Visibility: Don’t overlook the importance of a functional rear wiper blade during adverse weather conditions, as it ensures clear visibility and safety on the road.
