Hi, I have a2006 1.6 hdi 16v 9HX c3, I want to check the timing but can't see how to de-tension the drive belt.
There doesn't appear to be a tensioner. From the alternator it drops vertically to the air con pulley, then horizontal 90 degrees to the crank pulley, then 180 degrees back, (towards the front of the car) to a fixed pulley and finally 90 degrees up to the alternator. Any help, PLEASE

Hi chipmonk1212

If the 1.6 is like the 1.4 16v HDI then the tensioner is operated using a spanner on a lug that is the tensioner pulley.

It is quite easy to spot from the top of the engine.

I will try and dig out a picture,

But what bothers me is why you are trying to check the timing belt?

This is a view of the tensioner pulley from below

This is the tensioner pulley that has a drill bit inserted through the hole to hold the tensioner off the belt. Use an open ended spanner on the lug to overcome the spring tension and align the locking holes.

This is a new one from Euro Car Parts, but is upside down and the wrong angle to see the lug

Its good advice to replace any belts you remove because they are cheap and saves you doing the same job twice. You can find the right drive belt by clicking here (for Euro car parts) and use our forum discount code C3OWNER at the checkout for the forum discount ;)

Hi c3car, thanks for the reply.
yes , this is what the manuals AND Citroen tell you.
What they DON'T tell you is , for a period from 09-2005 to 03-2007 were fitted with a "stretch fit" belt, hence there is no adjuster
as I wanted to check the timing I noticed the auxiliary belt was very new and could read the belt number "GATES 6PK1090SF" I
went on e bay put in the number and all the relevant info from one of the advertisers. the tool "SFT001" is about £45 and its cheaper to buy the kit, which, includes the tool and belt than to buy them separate.
But all good now and hope this is useful

Hello,
Didn't want to clog up the forum with more of the same so I thought I'd ask here:


I'm having a similar problem with a 1.6hdi 2008. Eurocarparts is giving me 3 fan belt choices for my registration number - one is obviously not for my car as it states "no A/C" so I don't know if it's the 1090mm or the 975mm :?: ...

Hello

Either belts could be fitted to that engine on that year. You can remove your existing belt and measure it, order both and return one or call/email them to check the part number by VIN.
