Clearing Up the Confusion"},"content":{"rendered":"\n

A small internal component can make the difference between routine maintenance and the complete destruction of the engine. Questions about the timing system generate a flood of inquiries when people are looking for the exact specification\u2014 chain or belt<\/strong> \u2014for the 1.6 PureTech 180 cv engine<\/strong> to avoid surprises at the repair shop. <\/p>\n\n

Determining whether your vehicle uses a traditional system or a submerged mechanism is key to understanding its actual mechanical strength.<\/p>\n\n

Belt vs. Chain: Why This Question Matters So Much<\/strong><\/h2>\n\n

The type of drive system determines the vehicle’s maintenance requirements and reliability. While the chain typically lasts for the entire lifespan of the car, certain belt-driven systems require ongoing monitoring to prevent premature failure. <\/p>\n\n

What is the displacement of each PureTech engine?<\/strong><\/h2>\n\n

The design varies depending on the engine displacement and the model year of the engine block.<\/p>\n\n

The 1.2 PureTech (gasoline): oil-bathed belt<\/strong><\/h3>\n\n

The 1.2-liter engines are equipped with a 1.2 PureTech wet-belt timing system<\/strong>. This wet-belt<\/strong> configuration is designed to reduce internal friction, but it causes serious reliability issues. To see how this engine differs, check whether the 1.2 PureTech uses a timing belt or a timing chain<\/a>[cite: 1]. <\/p>\n\n

The 1.6 PureTech 180 CV: Belt or Chain?<\/strong><\/h3>\n\n

The 1.6-liter, 180 CV engine uses a<\/strong> metal timing chain<\/strong>. Unlike the 1.2-liter three-cylinder engine, this four-cylinder variant does not have a timing belt immersed in engine oil. <\/p>\n\n

BlueHDi Diesel: Why People Confuse Them<\/strong><\/h3>\n\n

Widespread confusion among drivers arises when commercial variants are offered under the same car models, even though they use completely different technologies and components.<\/p>\n\n

Why the “wet belt” (drenched in oil) is the problem<\/strong><\/h2>\n\n

The design of Block 1.2 conceals a serious manufacturing defect related to lubrication.<\/p>\n\n

How Does a Belt That Runs in Oil Work?<\/strong><\/h3>\n\n

The rubber component operates while permanently submerged in the lubricant to ensure smooth mechanical rotation.<\/p>\n\n

What Happens When It Dissolves: Residue and Blockages<\/strong><\/h3>\n\n

Continuous contact with gasoline causes the rubber to degrade. The debris falls into the oil pan, clogs the oil pump, and causes catastrophic failures costing over \u20ac7,000. <\/p>\n\n

“I’m wearing a chain, so I’m safe”: the myth<\/strong><\/h2>\n\n

Using a chain in the 1.6 engine prevents rubber degradation. However, drivers of the 1.2 with a 1.2 PureTech chain or belt<\/strong> should check the manufacturing date, as the chain versions are very recent. <\/p>\n\n

Can the strap be replaced with a chain?<\/strong><\/h2>\n\n

Many homeowners are looking to repair their damaged system.<\/p>\n\n

Is there a conversion kit?<\/strong><\/h3>\n\n

It is not possible to modify the engine block. Replacing the belt with a PureTech chain<\/strong> is not feasible due to the engine’s internal structure. <\/p>\n\n

Cost and why it doesn’t solve the underlying problem<\/strong><\/h3>\n\n

The design requires the use of the original replacement belt, so the risk of wear and tear reemerges as the mileage increases.<\/p>\n\n

What This Means for Your Right to File a Claim<\/strong><\/h2>\n\n

If you are experiencing this manufacturing defect in your 1.2-liter engine manufactured between 2014 and 2023, you can join the Stellantis PureTech class-action lawsuit<\/a> to request reimbursement for repairs and the corresponding compensation.<\/p>\n\n

Frequently Asked Questions<\/strong><\/h2>\n
\n
\n
\n

Does the 1.2 PureTech have a belt or a chain?<\/strong><\/h3>\n
\n\n

Models manufactured between 2014 and 2023 are equipped with an oil-bathed belt. Only the most recent hybrid models have begun to include a timing chain. <\/p>\n\n<\/div>\n<\/div>\n

\n

Does the reinforced strap solve the problem?<\/strong><\/h3>\n
\n\n

No, installing an updated replacement part only temporarily slows down wear and tear. Contact with fuel dissolved in the oil causes the material to degrade again over time. <\/p>\n\n<\/div>\n<\/div>\n

\n

How often should the PureTech’s timing belt be replaced?<\/strong><\/h3>\n
\n\n

It is recommended that you visually inspect its width during each maintenance check. It should be replaced sooner if it shows cracks, wear, or debris in the oil circuit. <\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
