In the automotive industry, certain manufacturers have moved toward a new timing belt design known as a “wet belt.” These timing belts operate submerged in oil, allowing them to be narrower, quieter, and more efficient. This design reduces friction, boosts fuel economy, and helps lower emissions, making engines run more smoothly and efficiently.
However, at TGPP-Autocare in Stevenage, we have seen specific issues with the wet belt in the 1.2 PureTech engine, especially for drivers who frequently travel short distances or drive in urban settings. The engine oil in these conditions may degrade more rapidly, leading to premature belt wear. This blog will explore common issues with the 1.2 PureTech and how our expert team at TGPP-Autocare can help you maintain your vehicle and avoid costly repairs.
Common Issues with the 1.2 PureTech Engine
The 1.2 PureTech engine, used in numerous Peugeot, Citroen, Toyota, DS, and Vauxhall models, has been subject to reliability concerns due to the wet belt design. The belt material can deteriorate over time, and particles from the worn belt may circulate in the oil, potentially clogging components like the oil pump strainer, variable timing solenoid valves, and vacuum pump. Left unchecked, these blockages can result in oil starvation, putting your engine at risk.
Which Vehicles Feature the 1.2 PureTech Engine?
The 1.2 PureTech engine is commonly found in the following models:
• Peugeot: 108, 208, 2008, 301, 308 II, 408 II, 3008, 5008, Rifter
• Citroen: Berlingo III, C1 II, C3 III, C3/C4/C5 Aircross, C3-XR, C4 Cactus, C4 Picasso
• Toyota: ProAce City, Aygo
• DS: 3, 3 Crossback, 4S, 7 Crossback
• Vauxhall: Combo E, Corsa F, Crossland, Grandland, Mokka
If you own one of these vehicles, it’s essential to understand the risks associated with the 1.2 PureTech engine’s wet timing belt. Our team at TGPP-Autocare is well-versed in maintaining these engines and can provide guidance on best practices to extend their lifespan.
Why Wet Belts Fail
While the wet belt system offers several benefits, it’s vulnerable to issues like oil contamination. In the 1.2 PureTech, unburned fuel can sometimes seep down the cylinder walls and mix with the oil in the pan, forming an abrasive mixture that accelerates belt wear. As the belt deteriorates, particles are released into the oil, creating the potential for blockages that can cause severe engine damage.
PSA Group’s Response: Recalls and Best Practices
In 2021, PSA Group (Peugeot and Citroen’s parent company) issued a recall on the 1.2 PureTech engine to address issues of premature belt wear caused by oil contamination. However, regular maintenance remains critical, as the underlying reliability issues associated with the wet belt design remain a concern.
TGPP-Autocare’s Recommendations for 1.2 PureTech Owners
If you own a 1.2 PureTech vehicle, here are some tips from our TGPP-Autocare team to help you maintain the timing belt and prevent engine issues:
1. Regular Oil Changes: Frequent oil changes are crucial for the wet belt’s longevity. Routine oil changes help remove contaminants and keep your engine well-lubricated, which is essential for these types of engines.
2. Use the Correct Oil Grade: Using the oil recommended by the manufacturer is essential, as this oil is specially formulated to resist dilution and wear in engines with a wet belt system.
3. Consider Upgraded Components: To reduce the risk of oil contamination, consider having TGPP-Autocare install high-quality aftermarket piston rings, which can help minimize unburned fuel reaching the oil pan.
