Keeping Your Engine in Perfect Time

Your engine is a finely tuned orchestra of moving parts, and the timing belt—sometimes called a cambelt—keeps the performance in perfect harmony. It connects the crankshaft and camshaft so your valves open and close exactly when they should. Modern “wet” belts run in engine oil, and replacing them at the right interval is vital to avoid major (and costly) engine damage.

Wet Timing Belts – A Quieter Twist on an Old Idea

Wet timing belts operate inside the engine, constantly bathed in oil. This design reduces friction, improves efficiency, and can be quieter in operation. They are found in many modern petrol and diesel engines, from Ford EcoBoosts to certain Peugeot, Citroën, Toyota, Vauxhall, and Volkswagen models. While they can last for years, they are not immune to wear and require attention before problems arise.

Why Replacement Matters

A worn or broken wet belt can cause catastrophic engine damage. When a belt fails, the pistons and valves can collide, bending or breaking critical components and often rendering the engine beyond repair. Over time, the belt can also deteriorate and shed rubber particles into the oil system, blocking filters and starving the engine of lubrication.

There are several reasons wet belts fail. Age and mileage cause the materials to weaken over time. Poor-quality or infrequently changed oil can accelerate belt degradation. Leaks from coolant or other fluids may soften or damage the belt prematurely. In some cases, tensioner or pulley failure puts excessive strain on the belt. Neglecting scheduled servicing increases risk, as does harsh driving—frequent short trips, heavy towing, or aggressive acceleration all speed up wear.

Pro tip: Don’t wait for warning signs—belt replacement is far more affordable than an engine rebuild.

What’s Involved in Replacement

Replacing a wet timing belt is a precise and involved process. The job typically requires removal of the sump and a thorough cleaning of the oil system to prevent contamination. Associated seals, O-rings, and the oil pump drive components are replaced, followed by fresh oil and filter changes. Specialist locking tools are used to ensure perfect engine timing.

On engines like the Ford EcoBoost, exact alignment is critical to performance and longevity. PSA 1.2 L engines often require additional work, including replacing multiple gaskets and pulleys as part of the process.

How Long & How Much?

Wet belt replacement is not a quick job. Depending on the engine layout, it can take between one and two days to complete. Costs vary depending on the make and model of your vehicle, as well as the complexity of the work required.
