The Ford 1.0L Ecoboost offers excellent fuel economy and surprising performance, making it attractive on the used market. However, buyers need to be aware of potential issues. This guide will help you make an informed purchase decision.
Before Viewing: Initial Checks
Service History
A complete service history is essential for Ecoboost engines. Ask for:
- Full dealer or specialist service stamps
- Evidence of correct oil specifications used
- Any cooling system work performed
- Records of Ford service actions or recalls
HPI Check
Run a vehicle history check to verify:
- No outstanding finance
- Not stolen or written off
- Mileage consistency
- Number of previous owners
MOT History
Check the GOV.UK MOT history for:
- Mileage progression
- Previous advisories
- Any emission-related failures
Physical Inspection Checklist
Cold Start Test
This is crucial. View the car when it’s been sitting overnight:
- Watch exhaust on start-up – White smoke could indicate coolant burning
- Listen for unusual noises – Ticking, knocking, or rattling
- Check idle quality – Should be smooth and stable
- Rev the engine – Look for smoke under acceleration
Under the Bonnet
- Coolant level – Check expansion tank is at correct level
- Coolant condition – Should be clean, not oily or discoloured
- Oil cap underside – Check for mayonnaise-like deposits (indicates coolant contamination)
- Oil level and condition – Check dipstick
- Visible leaks – Look for coolant or oil around the engine
- Hoses and connections – Check for cracks or deterioration
Test Drive
During your test drive, note:
- Temperature gauge – Should sit stable in the middle
- Engine performance – Good power, no hesitation
- Any warning lights – Should stay off
- Exhaust smoke – Check mirrors during acceleration
- Clutch operation – Smooth engagement, no slipping
- Gearbox – Clean changes, no grinding
Professional Inspection
For peace of mind, consider a professional pre-purchase inspection:
Cooling System Pressure Test
This test can reveal internal leaks not visible externally. Ask a mechanic to pressurize the cooling system and monitor for pressure loss.
Compression Test
A compression test reveals the health of pistons, rings, and valves. Variations between cylinders can indicate problems.
Diagnostic Scan
A proper Ford diagnostic tool can reveal stored fault codes, even if warning lights aren’t currently showing.
Red Flags to Walk Away From
- White smoke from exhaust (especially when warm)
- Coolant level dropping during inspection/drive
- Milky residue under oil cap
- Missing or incomplete service history
- Pressure to view when engine is warm
- Sweet smell from exhaust or engine bay
- Temperature gauge rising higher than normal
- Rough running or misfires
