Last updated: July 2026 — every figure on this page was checked against the named UK sources on 8 July 2026.
Caught before failure, a wet belt change is £800–£1,200 and almost always worth doing. After failure, engine damage can push bills past £4,000 (Honest John) — and on most affected cars that fails every repair-value test.
One step before any maths: if the car is a Peugeot, Citroën, Vauxhall or DS with a 1.0/1.2 PureTech, Stellantis may pay the whole bill.
Step 0: check the Stellantis warranty first
Stellantis has officially extended cover on affected earlier-generation 1.0 and 1.2 PureTech engines to 100% of parts and labour for up to 10 years or 112,000 miles, and runs a compensation platform for qualifying repairs paid between January 2022 and December 2024 (stellantis-support.com). If your car qualifies, the repair-or-scrap question answers itself — claim, do not scrap. Ford EcoBoost owners have no equivalent blanket scheme on our sources, but it always costs nothing to ask the dealer about goodwill on a documented failure.
The two scenarios, priced
| Scenario | Typical cost | Source |
|---|---|---|
| Preventative belt change (independent) | £800–£1,200 | Honest John |
| Belt + oil system cleaning (real jobs) | up to £2,000 | Honest John / FixMyCar range |
| Engine failure after belt let-go | £4,000+ | Honest John |
| Replacement EcoBoost engine fitted | ~£5,600 average | Bumper |
If the belt has NOT failed yet: repair, almost always
A £800–£1,200 preventative change passes the insurers’ 50–60% repair-to-value test (AA; RAC) on any car worth £2,000+. The affected Fords, Peugeots, Citroëns and Vauxhalls are mostly 2012–2020 cars still worth £3,000–£10,000 — the belt is maintenance, not a write-off event. The exception: a sub-£1,500 car that also needs other work; there the £279 average scrap payout (CarTakeBack) or a trade sale with full disclosure may beat spending near the car’s value on a belt.
If the belt HAS failed: usually scrap or sell — with one check
Once shed rubber has starved the engine of oil, you are pricing an engine, not a belt: £4,000+ per Honest John, ~£5,600 average for a replacement EcoBoost engine per Bumper. Against typical values of the affected cars, that fails the 60% rule almost every time. The one check before scrapping: how far the damage actually went — if the engine stopped from low oil pressure but turns freely and a compression test comes back healthy, some cars survive with belt, cleaned oil system and new pickup for £1,500–£2,000. Ask a garage to assess before you call the scrapyard — and if it is a PureTech, back to Step 0.
Selling instead of scrapping
A wet-belt casualty with a good body and interior is a known quantity to trade buyers and breakers — the engines, gearboxes and panels have value beyond the £200–£279 weight-based scrap averages (Scrap Car Comparison notes salvageable parts raise the price). Be honest about the failure; these cars are bought for exactly this fault every day. Legal basics if you do scrap: ATF, Certificate of Destruction, tell the DVLA or risk a £1,000 fine (gov.uk).
Frequently asked questions
My PureTech’s belt failed and I already paid — too late for Stellantis?
Maybe not: the compensation platform covers qualifying repair expenses paid between January 2022 and December 2024, and the warranty extension runs to 10 years or 112,000 miles. Check your case at stellantis-support.com or a dealer before writing the money off.
The car still runs but has wet belt symptoms — which scenario am I in?
The good one, just barely. Stop driving, get the belt and oil pickup inspected, and you are likely still in £800–£2,000 territory rather than £4,000+. Every mile driven on symptoms moves you towards the second table row.
Is a car with a replaced engine worth keeping?
At ~£5,600 for a fitted EcoBoost engine (Bumper), it rarely makes sense on cars worth less than £7,000–£8,000 — and even then only with a warranty on the replacement engine. Most owners sell to trade at that point.
Will a scrapyard pay less because the engine is dead?
Scrap value is weight-based — £200–£279 on current averages — so a dead engine barely moves it. A breaker who wants the car for parts may pay more than a scrapyard; get quotes from both.
