Does My Van Have a Wet Belt?

Which vans have wet belts? (quick list)

The quickest way to be sure for your van is to run your registration through the free van wet belt checker — it matches your exact engine and tells you whether it's a wet belt, when it's due, and the typical cost.

What is a wet (belt-in-oil) timing belt?

A wet timing belt runs inside the engine, submerged in oil, rather than outside behind a cover like a traditional dry belt. Manufacturers used them to cut noise, weight and emissions, but the oil degrades the rubber over time and the belt sheds material as it breaks down.

Ford vans — the biggest wet belt group

Ford is the single most important make for van wet belts in the UK. The 2.0 EcoBlue diesel (2016 onwards), fitted to the full-size Transit, Transit Custom and Tourneo Custom, uses a wet "belt-in-oil" system and is a well-known failure point. The smaller Transit Connect and Transit Courier use the 1.0 EcoBoost petrol, which is also a wet belt.

• Use only Ford's specified oil (WSS-M2C950-A) and keep strictly to the service schedule — oil quality is central to belt life.
• Many specialists recommend proactive replacement around 60,000 miles on high-mileage working vans.
• Always have the separate oil-pump belt replaced at the same time as the main belt — ask, as some dealers don't do it automatically.

Peugeot Partner, Citroen Berlingo & Vauxhall Combo

These three are the same Stellantis platform. In petrol form they use the 1.2 PureTech (EB-series) engine, whose earlier generation has an oil-immersed wet camshaft belt — the engine family at the centre of Stellantis's belt issues.

• Stellantis acknowledged premature belt deterioration on earlier EB engines and later moved toward a chain, so confirm the exact engine and build date.
• The diesel (1.5 BlueHDi) versions of these vans do not use a wet belt.
• Replace the belt and tensioner together.

Toyota Proace City

The Toyota Proace City is a rebadged Stellantis van. In petrol form it shares the same 1.2 PSA-derived wet belt engine as the Partner, Berlingo and Combo. The diesel version does not use a wet belt.

VW Transporter — the newest exception

The new (2025 onward) VW Transporter T7 is Ford-derived and uses the Ford 2.0 TDI (EcoBlue "Panther") engine — so it inherits the wet belt-in-oil design. This breaks the usual assumption that VW diesel vans are chain-driven.

How do I know for sure?

1. Use the free checker — enter your reg on the van wet belt checker and it cross-references your van against our mechanic-verified database.
2. Check the V5C — the engine code and fuel type are on your logbook.
3. Check the year and fuel type — a petrol 1.0/1.2 van after 2013, a 2016-on Ford EcoBlue diesel, or a 2025-on VW Transporter is likely a wet belt.
4. Ask your garage — any competent mechanic can confirm from the make, model year and engine.

What does it cost?

Van wet belt replacement typically costs £450–£1,200 depending on the engine — the Ford 2.0 EcoBlue is at the higher end because the main belt plus a separate oil-pump belt are replaced and sump removal is often required. Compare that against a destroyed engine (£3,000–£6,000+) plus weeks of lost earnings while the van is off the road, and proactive replacement is the obvious call for a working vehicle.
