So... What is a 'Wet' belt?
Well, a 'wet' belt is a nickname given to a specific design of timing belt. This design on timing belt runs internally and is lubricated by the engine's oil, in a similar fashion than that of a timing chain. This design is becoming increasingly popular among manufacturers, such as Ford, Peugeot, Volkswagen and more, this is because they weigh less than a metal timing chain and have far less friction than a traditional "dry" timing belt design. This results in improved fuel efficiency and reduced emissions, making it a more environmentally friendly option!
When should i have my Wet belt replaced?
Although Wet timing belts were designed to last up to 10 years or 120,000 to 150,000 miles, depending on the manufacturer, they have been known to fail as early as 30,000 miles, or even less in some cases!
If your vehicle has already covered 50,000 miles or more, and you're not sure if your wet belt has already been replaced, we strongly recommend having it replaced soon. This will help keep your vehicle running smoothly and prevent any potential damage, that could cost you thousands in repairs!
Why are they failing early?
The presence of oil impurities such as soot and other debris can have a detrimental effect on the timing belt of your engine. The belt can become weakened due to these impurities getting between the belt teeth and pulleys. Additionally, wear on the outer belt coating can expose the underlying materials to oil, which may contain unburnt or partially combusted fuel that can attack the exposed belt materials. This can cause the teeth to detach, leading to slipping pulleys and changes in engine timing, it can also cause a blockage in the oil pump caused by build up of belt debris. This can lead to low oil pressure leading to serious internal engine damage. To minimise such issues, it's crucial to maintain clean engine oil and change it regularly.
