Citroën C1 1.2 Puretech 2014 timing belt interval

[Nego2403]

Hello

I have just bought a Citroën C1 from 2014 with the 1.2 Puretech engine. I know that there has been some problems with the timing belt on these engines and therefore I want to know the intervals for changing the belt. The car has done 111.000 km and the belt has not been changed by now. The VIN of the car is VF7**************[VIN obfuscated, can be read by forum staff].

Furthermore water is dripping from the rear top brake light into the cabin. How can this be fixed? I took the seal off on the backside of the light and removed the water but I don't understand how the water could enter the light.

Best regards
Nikola

Every 175000 Km / 10 year(s) for your vehicle under 'Normal' conditions or Every 165000 Km / 10 year(s) for 'arduous countries / use.

The rear screen washer pipes run via the rear high level brake light, so if the pipe has worked loose, then water will start getting in. I would check to make sure the pipe is securely fastened on:

Thank you. The liquid looked like water and it didn't smell like washer fluid. I'll take the seal of again and run the washer to see if the light is filling with fluid.

Either that or if it has been raining you may have a crack in the lens - look around any screws that secure the lens it for a spider web-like pattern. This can be a tress crack caused by the screw over time. A few vehicles suffer with this and Citroen simply replace the lens cover.

I will check this out and come back with a conclusion in case others experience this issue

For future work what tools are necessary for locking the camshafts and crankshaft? Do you have a manual for this operation? I just talked to Citroën in Denmark they told me that the interval was 100.000 km or 6 years what is the reason in the different intervals?

[GiveMeABreak]

I just quoted the interval from Citroen service from your VIN.

The timing belts on the EB2 engines require frequent checks because of the 'Belt In Oil' system, that can result in the timing belt material shredding, so they should be inspected regularly (you can view the condition via the oil filler port). The shedding of the belt material can build up, blocking the oil strainer and lead to oil starvation in the engine oil channels. This can then lead to the engine oil pressure warning light coming on. At this stage it can lead to a catastrophic engine failure resulting in a new engine.

It is essential to use the correct oil specifications recommended for the EB2 engines for this reason. They also replaced the early belts with improved material as far as I am aware.

If Citroen have recommended an earlier replacement then that can only be a good thing, so I would certainly go with the earlier checks and replacements for these reasons.

[Nego2403]

Yes this makes sense. I also think that he told me to do it earlier due to this issue. I looked at the belt before buying the car through the oil filler cap. It looked a bit rough on the rubber like it had small pits in it. The size of these pits is around 1x1mm and they're covering the whole belt. I'm assuming the belt isn't 100% smooth from the factory. The dry belt I did on my C3 had some pits like this probably from the manufacturing process. This said the belt didn't have any cracks so I would assume it's good for now. I would like to do the belt early rather than the belt failing and giving me much bigger expenses. The belt seems rather straight forward to replace. But I've seen that there is two versions of this engine one has a plastic rocker cover which when removed is exposing the camshafts. The other model I think it's called 1.2 Puretech GDI has an extra metal part before the camshafts which is also sealed to the cylinder head with a RTV gasket.
On both models the plastic rocker cover is sealed with a rubber gasket.

The model with the extra metal part:

The model where the camshafts are exposed after removing the plastic rocker cover:

Do you have a manual for this procedure?

[GiveMeABreak]

I don't for the C1 (B4) version unfortunately.

[Nego2403]

I don't for the C1 (B4) version unfortunately.

Ohh okay it looks pretty straight forward. Probably going to be time consuming I haven't done this engine before

[Nego2403]

Do you know the tightening torques for the dephasers, idler pulley, tension pulley and the crankshaft bolts?

[GiveMeABreak]

I don't, but the Transmission, engine - gearbox assembly, alternator and oil sump need coming off from what I can tell. It's quite an involved job....

[Nego2403]

I don't, but the Transmission, engine - gearbox assembly, alternator and oil sump need coming off from what I can tell. It's quite an involved job....

I removed intake, rocker cover. The intake was hard to get out but I removed the engine mount and managed to pull the engine a little forward to get the intake out. I didn't remove the sump but probably should to check the oil pickup for rubber. The crankshaft gear just came out easy when the large bolt on the crankshaft was removed. Also the alternator was not in the way it is pretty high up over the ac compressor. It's pretty accessible from underneath. The only issue I have is that I don't know the correct tightening torques which PSA is advising. I tried googling and found a Portuguese video on YouTube which states the following tightening torques which I used.
The tensioner and idler should be tightened to 20 Nm.
The crank bolt to 50 Nm and 180 degrees.
The dephasers to 20 Nm and 120 degrees.
The 3 crankshaft pulley bolts to 30 Nm.
The metal part between the head and the rocker cover to 10 Nm.
The cover for the inspection hole on the side of the engine, rocker cover and intake bolts to 8 Nm.

I hope this information will be useful for someone doing the same job in the future.

I’ve been looking for the right oil for my Daughters Citroen C1, mk2, 1.2 litre Puretech Engine after contacting Citroen I was given OW/30 and 5W/30. The Citroen Garage who does Major work to need for her car insists Puretech 1.2 and 1.0 litre engines need 0W/30 fully synthetic ACEA B3. Having Your Cambelt changed in these engines are not the easiest job to do. It does involve removing the cambelt side of the engine. Citroen did say it’s easier too remove engine and quoted me £1200-£1400 to do. It may be easier too replace engine with low Milage salvaged engine. I saw one the other day, a early 2019 Citroen C1, mk 2, 1.2 litre engine with proof mileage 18000 miles for £465.

There are multiple variants of this engine so must be an exact match.... If you want to know the correct oil, pop your VIN up.
