hi all,

 

my 05 (55 reg) 2.0 hdi picasso is almost at 80k miles now and i will be starting a new job in august where i will be covering 60 miles per day commuting so now i feel it's time to get the original as i suspect cambelt and water pump changed.

now is this a hard job to do DIY or is it best left to a professional citroen specialist or the dealer?

also how much is this likely to cost?

 

thanks in advance

My opinion- DIY is no great problem. Go about the job slowly and carefully. This is one subject that Haynes covers quite well.

I suggest a Gates complete kit, belt, pulleys, pump.

Check the crankshaft seal while you are there- if you replace use genuine.

It is recommended that Citroens special gauge is used to tension belt. Rubbish! The old school method is just as good- get hold of the belt between thumb and forefinger on the longest section and twist the belt through 90 deg. When the tension is right you will get the feel that any more than 90 deg. will start to make your fingers ache.

thanks for the reply,

 

i have a few weeks off in july so i will either attempt it DIY then (my only concern is if it snaps or has any problems then it's my problem) or take it to a garage to get it replaced.

 

i think the current belt on it is okay as it doesn't make any weird noises but i know it can just snap anytime and this being an interference engine it will cause some damage.

but i will be getting it replaced in the next few months so hopefully it holds on

I have a detailed question on cambelt change that I suspect only a Citroen trained person with access to official data can answer. Opinions are of little use - I need an proper answer please!

 

The car is a 2006 Xsara Picasso with 1.6 petrol 16 valve. Therefore 12 years old but only 67,000 gentle miles, mostly longer runs. The official belt change interval seems to be 75,000 so it is about time.

 

HOWEVER, I asked at a Citroen dealer about belt prices, tensioner kit options etc. I was told that if a new Citroen belt (Part no C816H6) is fitted then the CRANKSHAFT pinion (the toothed wheel behind the crankshaft pulley for the aux belt and that the cambelt engages with) must also be changed to a new part C9674617680 (£58 + VAT) and after consulting the workshop I was told this was 100% imperative - BUT NO REAL REASON GIVEN WHY.  No-one else I speak to has heard of this but it is certainly on the Citroen computer system when you look up the parts list - also a revised timing belt replacement procedure is mandated - but I have no idea what this is.

 

Now, this job is pretty standard - lock the crankshaft and the camshafts and the tension is taken care of automatically when the new belt is fitted. In this respect it is much easier than the old 8 valve engine. According to Haynes Manual the cambelt even has white lines on it to align with marks on the camshaft wheels etc

 

So WHY is it advised or ORDERED that a new CRANKSHAFT pinion wheel be fitted. It was suggested I could fit a non-Citroen belt (as many or most people do) and (OBVIOUSLY??) the old pinion wheel would be OK - it has been OK for the last 12 years and there are no noises or other problems.

 

Is this Citroen cambelt C816H6 somehow a new design and incompatible with the original pinion wheel??? If so why does it suit the existing camshaft wheels and water pump?

 

I'm looking for a definitive and logical answer please. Citroen wouldn't allow access to workshop manual material (of course).
