How much does a Ford Puma ST 1.5 EcoBoost engine replacement cost-

A full rebuilt or reconditioned Ford Puma ST 1.5 EcoBoost engine typically costs between £2,200 and £3,500, including supply and fit. Rebuilt units include upgraded performance components and a 12-month warranty. Main dealers often charge £6,000-£8,000+ for the same replacement. Used engines are a budget alternative, starting from around £1,200.

Does the Ford Puma ST 1.5 EcoBoost have the wet belt problem-

The Ford Puma ST 1.5 EcoBoost uses a hybrid setup: a timing chain for the camshafts, but a wet belt for the oil pump. Unlike automatic Puma models, the manual ST does not have the problematic oil pump belt tensioner. However, the wet belt itself can still degrade over time and shed debris, making preventative replacement at 60,000 miles highly recommended.

Is it worth replacing the engine in a Ford Puma ST 1.5 EcoBoost-

Yes, absolutely. The Ford Puma ST retains strong market values, typically ranging from £18,000 to £28,000. A full rebuilt engine replacement (£2,800-£3,800) represents a small fraction of the vehicle's total worth. Investing in a warrantied, reconditioned unit preserves the car's performance and resale value far better than a cheap, unverified used engine.

What are the signs of a burnt valve in a Ford Puma ST 1.5 EcoBoost-

A burnt exhaust valve on cylinder 1 is a documented low-mileage failure in this engine family. Signs include a sudden, severe loss of power or a persistent misfire, illumination of the check engine light, and a noticeable lack of compression on cylinder 1 during a mechanic's test. If you notice these symptoms, stop driving and get your Ford Puma ST 1.5 EcoBoost inspected immediately.

How long does a Ford Puma ST 1.5 EcoBoost engine replacement take-

A standard Ford Puma ST 1.5 EcoBoost engine swap typically takes 5 to 7 working days. This includes sourcing the correct 200 PS performance unit, nationwide delivery to your chosen specialist, and physical installation, ECU calibration, fluid top-up, and comprehensive road testing.

Variant History

Ford Puma ST 1.5 EcoBoost Engine History & Specs at a Glance

When the Ford Puma ST launched, it brought hot-hatch performance to the crossover segment, utilizing a highly tuned 200 PS version of the 1.5-litre EcoBoost three-cylinder engine, shared with the acclaimed Fiesta ST.

2021
1.5 EcoBoost ST (200 PS) introduced in the Ford Puma ST, featuring a timing chain for the camshafts but retaining a wet belt for the oil pump drive.
2021
Present - Continuous production with minor software refinements. Crucially, the manual transmission variant avoids the oil pump belt tensioner found in automatic Puma models, slightly reducing one potential failure point.

Common failure points and repair options

Burnt Exhaust Valve (Cylinder 1)

Affected: Ford Puma ST 1.5 EcoBoost (2021-present)
Typical failure mileage: 20,000-40,000 miles

Root cause

High thermal load and specific combustion dynamics in the three-cylinder layout can lead to premature exhaust valve degradation on cylinder 1, resulting in a sudden loss of compression and requiring a complete engine replacement.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative	N/A	N/A
Full Replacement - rebuilt/reconditioned engine	£6,000-£8,000+	£2,800-£3,800

Our recommendation

Given the high value of the Puma ST and the catastrophic nature of a burnt valve or oil starvation, a professionally rebuilt engine with upgraded valve train components and a new oil pump belt is the most reliable long-term solution. Do not attempt to run the vehicle if an oil pressure warning or sudden misfire occurs.

Wet Belt Oil Pump Degradation

Affected: Ford Puma ST 1.5 EcoBoost (2021-present)
Typical failure mileage: 60,000+ miles

Root cause

While the ST uses a timing chain for the camshafts, the oil pump is driven by a wet belt. Over time, this belt can degrade and shed debris, clogging the oil pickup strainer. (Note: The manual ST avoids the automatic transmission's problematic oil pump belt tensioner, but the belt itself still requires monitoring).

Repair options

Repair tier	Dealer price	Specialist price
Preventative Belt Replacement	£1,000-£1,500	£800-£1,200
Full Replacement - rebuilt/reconditioned engine	£6,000-£8,000+	£2,800-£3,800
