1.2 PureTech timing belt: intervals by build date, the wet belt and the parts

A timing belt that runs in oil

The EB2 three-cylinder drives its camshafts with a belt that runs in the engine oil, known as a wet belt. NTN-SNR, which makes timing kits for this engine, describes the failure in its TECHinfo bulletins. On cars that cover under 15,000 km a year, mostly in town, fuel dilutes the oil and the mixture wears the belt.

Belt debris can then block the oil pump strainer and the variable valve timing solenoids. On the turbo versions it can also block the vacuum pump that feeds the brake servo, and a safety recall followed. SNR gives the recall codes as JZR for Peugeot and HFC for Citroën and DS, for 1.2 PureTech 110 and 130 engines built between March 2013 and April 2017.

1.2 PureTech timing belt intervals, with dates

Each figure below carries the date and the source that reported it. Match the interval to the build date of the car in front of you.

• Built up to March 2017 (Citroën, DS, Peugeot): replace every 10 years or 175,000 km. L’argus, 24 March 2024.
• Built from April 2017 (Citroën, DS, Opel, Peugeot): replace every 6 years or 100,000 km. L’argus, 24 March 2024, and the NTN-SNR bulletins give the same figure.
• Belt condition checked at every annual service. L’argus, 24 March 2024.
• 20 June 2022: a new timing belt reference goes into production. L’argus, 24 March 2024.
• 16 February 2023: Peugeot announces the new-generation 136 hp PureTech for its 48V hybrid, with a timing chain. Stellantis press release.
• 19 March 2024: warranty extended to 10 years or 175,000 km for 1.2 PureTech engines built from April 2014 to 20 June 2022. L’argus, 24 March 2024.
• 17 January 2025: Connexion France reports compensation claims for repairs made between 1 June 2022 and 18 March 2024 that followed the maintenance plan.

The belt check gauge

The oil filler on the EB2 sits above the belt, and the manufacturer recommends checking the belt through it at routine services. The check is a width measurement with a belt gauge, listed in SNR’s bulletin under OE reference G-0109-6, taken at three points as the crankshaft is turned.

A belt that fails the width check leads to an inspection of the oil pump strainer, and the job grows from there. The catalog lists the parts for that job, and the procedure belongs to the workshop documentation.

The belt kit by engine version

SNR’s two bulletins split the 1.2 PureTech into naturally aspirated and turbo versions. The naturally aspirated list includes HMZ (EB2F) for the VTi 82 and PureTech 82, HMY (EB2M) for the 72 hp version and HMR (EB2FA) for the PureTech 83. The turbo list includes HNZ (EB2DT) at 110 hp and HNY (EB2DTS) at 130 hp, plus the EB2ADTD at 100 hp and the EB2ADTX at 155 hp.

Both lists point to the same SNR kit, KD459.70, and the jobs still differ. The seals SNR says to replace every time are not the same: the naturally aspirated list includes three intake manifold seals, the turbo list an oil separator seal and a vacuum pump seal. On the turbo engine, a belt that needs replacing also means a new vacuum pump.

Build date adds a third variable, since the belt reference changed in June 2022, and the 48V hybrid engine uses a chain and takes no belt kit at all. Decode the VIN in the Peugeot parts catalog for the engine code and the parts of that build, and see timing belt and chain parts by VIN for the kit logic that applies to any engine. Our list of Peugeot engine codes covers the rest of the range.

Oil grade and approval

On this engine the oil is part of the belt’s life. The warranty conditions L’argus reported list 5W30 for cars built before August 2018 and 0W20 after that date.

TotalEnergies, whose oil Stellantis uses as factory fill, lists Quartz Ineo Xtra First 0W-20 under the PSA B71 2010 approval and names the EB2DT among the engines it suits. SNR’s view is that on cars used little, mostly in town, an oil change every year is the only protection for the belt. Take the grade and approval for a given car from its handbook or service schedule.

The limits of these figures

The intervals and dates here come from L’argus, Connexion France, a Stellantis press release and NTN-SNR’s bulletins. We could not open Stellantis’s own warranty announcement or a Peugeot service schedule, and we found no published interval for the chain engine, so we give none.

The service schedule for the car’s VIN, from a dealer, is the final word on its interval. The catalog gives you the parts, the diagrams and the supersessions, and the repair method comes from the workshop documentation.
