Understanding PSA & Ford Wet Belt Systems

June 24, 2024

The automotive industry continuously evolves, introducing innovative technologies to enhance performance, efficiency, and sustainability. One such innovation is the wet belt system, utilised by major automakers like PSA Group (Peugeot, Citroën, and recently, Vauxhall/Opel) and Ford. These systems were designed to reduce friction and wear, improve durability, and decrease noise compared to traditional timing chains and dry belts. Here’s a detailed comparison of the PSA and Ford wet belt systems.

History and Introduction

Ford launched its wet belt system with the introduction of the 1.0L EcoBoost engine in 2012. This engine was designed to offer an efficient, powerful alternative for smaller vehicles, focusing on reducing emissions and improving fuel economy.


PSA Group introduced their wet belt system around the same time, incorporating it into various engines used across their range of brands. This system was part of PSA’s broader strategy to enhance engine longevity and efficiency.

Purpose and Technology

Both Ford and PSA implemented wet belt systems to:

  • Reduce the operational noise of the engine.
  • Extend the lifespan of the belt by running it in an oil bath, thus reducing wear and tear.
  • Decrease the overall engine maintenance costs for owners.

Differences in Design and Application

While the basic concept of a wet belt system is similar—using a belt submerged in oil—there are nuances in how Ford and PSA have implemented the technology:

  • Ford’s EcoBoost engines, including the popular 1.0L variant, use the wet belt mainly for smaller, turbocharged engines that need to balance performance with efficiency.
  • PSA’s engines often utilise the wet belt in a broader range of engines, reflecting their diverse lineup of vehicles that include not only compact cars but also larger family vehicles and SUVs.

Reliability and Common Faults

Ford Wet Belt System:

  • Common Faults: Premature belt wear has been a notable issue, especially if the oil isn’t changed regularly or becomes contaminated.
  • Reliability: There have been reports of early failures, leading to expensive repairs if the belt snaps, as it can cause significant engine damage.

PSA Wet Belt System:

  • Common Faults: Similar to Ford, the reliability of the PSA wet belt can be compromised by poor maintenance, particularly neglecting regular oil changes.
  • Reliability: PSA has made efforts to improve the durability of their wet belts in newer models, but like any such system, maintenance is key to longevity.


Both Ford and PSA have made significant strides with their wet belt systems, but the success of these systems largely depends on regular and proper maintenance. Regular oil changes and adhering to maintenance schedules are crucial to avoid the pitfalls of wet belt failures.

In terms of which is more reliable, it largely depends on the specific model and how well it has been maintained. Both systems have their merits, but also their challenges, primarily related to maintenance and the potential costs of belt failure.


For owners of vehicles with either Ford or PSA wet belt systems, it’s essential to maintain vigilance with scheduled services to ensure that the benefits of these innovative systems can be fully realised without untimely setbacks.
