Weak points
Known weak points to check
These are structured model-profile checks already present in the Duewise catalog. They are not a diagnosis of any individual car.
high risk · common from 70,000 miles
Wet belt / belt-in-oil deterioration
The 1.0 EcoBoost uses a belt-in-oil system. Wrong oil, long service intervals or missing history increase buyer risk.
How to check
Ask for wet-belt replacement evidence, correct oil specification and annual service invoices.
high risk · common from 50,000 miles
Coolant loss / overheating history
Coolant loss can cause serious engine damage if ignored.
How to check
Check coolant level cold, residue around tank/hoses, heater performance and overheating history.
medium risk · common from 60,000 miles
Clutch wear / judder
City use and learner-driver history can accelerate clutch wear.
How to check
Check biting point, clutch slip, judder when pulling away and reverse engagement.
Service evidence to request
essential
Correct oil service history
Correct oil and regular servicing are critical on belt-in-oil EcoBoost engines.
Ask for invoices showing oil specification, date and mileage.
essential
Wet belt evidence
Missing wet-belt evidence should be treated as a major negotiation point.
Ask for a dated invoice showing belt work, mileage and garage details.
Mileage-sensitive checks
From 60,000 miles
Coolant and clutch evidence becomes more relevant
City use can accelerate clutch wear, and coolant issues should be treated carefully.
From 70,000 miles
Wet-belt evidence becomes central
At this mileage, correct oil and wet-belt evidence can be the difference between manageable and expensive risk.
