Parts for the Ford Mustang EcoBoost

Known issues

Owners of Ford Mustang EcoBoost vehicles in New Zealand should be aware of a few potential issues:
• Intercooler Condensation: In humid conditions, condensation can build up in the intercooler, potentially leading to misfires. Regular checks and potentially a modified intercooler setup can mitigate this.
• Turbocharger Reliability: While less common than in earlier versions of turbocharged engines, some EcoBoost Mustangs have experienced turbocharger failures. Listen for unusual noises and maintain proper oil change intervals.
• Automatic Transmission Issues: Some owners have reported issues with the automatic transmission's shift quality. Regular AUTOMATIC TRANSMISSION FLUID changes are crucial.
• Wheel Bearing & Suspension: From roughly 80,000 km onward, the WHEEL BEARING KIT/HUB REAR should be assessed for wear. Ensure to investigate for any noises or degraded handling issues to maintain proper ride performance.

WOF tips

When your Ford Mustang EcoBoost undergoes its Warrant of Fitness (WOF) inspection in New Zealand, be mindful of the following:
• Tyre Wear: The independent rear suspension can sometimes lead to uneven tyre wear, so pay close attention to tyre condition.
• Brake Dust: Excessive brake dust, particularly on models equipped with Brembo brakes, could indicate potential brake issues. This should be investigated thoroughly to ensure braking system integrity.

About the Ford Mustang EcoBoost

Performance & Practicality

The EcoBoost Mustang promises a thrilling driving experience, perfectly suited for New Zealand's varied landscapes while prioritizing fuel efficiency. For those who desire the Mustang’s legendary performance without the hefty fuel costs of a V8, the EcoBoost stands out as an ideal choice.

Regular maintenance is essential for keeping your Mustang in top shape. Key components to watch are the Automatic Transmission Fluid, which should be checked every 20,000km or as per the service schedule to ensure smooth shifts. Pay close attention to your shocks and struts; replacing them every 80,000km helps maintain optimal ride quality.

Routine checks of your thermostat housing can prevent overheating issues, while regular replacement of wiper blades ensures clear visibility during New Zealand's unpredictable weather. Components such as the knock sensor and map sensor should be monitored regularly, with replacements performed when necessary. Don't overlook the suspension, either—the suspension bush radius arm should be inspected for wear to retain handling performance.

Braking performance is crucial, so keeping an eye on your rear brake pads and having them checked along with your front brake service regularly is key to safety. If you’ve noticed any noises from the rear, it might be time for a rear brake service to replace components and prevent potential issues. Lastly, with a focus on the cooling system, regular inspections around the 150,000km mark are advised to check your water pump, thermostat, and radiator hoses, which connect to this cooling category. Regular care and attention can ensure that your Mustang EcoBoost continues to perform at its best for many miles to come.
