Reliability Analysis

With a risk score of 7.0/10, this engine requires vigilance. While millions run fine, the risk of sudden coolant loss leading to a cracked head or fire is documented. It was eventually replaced by the 1.5 EcoBoost, which fixed many of these issues.

Caution

Autoscore Verdict

Caution. Fun to drive, but risky reliability. Ensure all cooling system recalls are done and monitor coolant weekly.

Coolant Loss & Fire Risk

The 1.6 EcoBoost has a known design flaw where localised overheating can crack the cylinder head. This can cause pressurized oil to leak onto the hot exhaust manifold, leading to engine bay fires. Ford issued recalls to install coolant level sensors, but the underlying vulnerability remains if cooling is neglected.

Typical Mileage: 100,000 km

Cost: €1000–3000

Buyer's Inspection Checklist

Check if the recall (coolant level sensor installation) has been performed.
Inspect coolant level and look for signs of dried coolant around the engine.
Test drive for any signs of overheating.
Ask if the timing belt has been changed (due every 10 years).
