For reasons best known to themselves, this is factory fit by PSA!!?? Presumably though yours is he earlier engine that does not have the water pipe up the back cover obscuring access to the already difficult bolt down the back
No it doesn't thankfully.
Congrats on the new addition Richard, Jim mentioned it the other day when i spoke to him.....Its nice to get a car that needs little done to it
As to how much needs
doing and how much I'll
do is a different matter
Sunday was a rather busy day as I ran into a couple of stumbling blocks in the process of changing the timing belt which delayed the job by a few hours, firstly I have a specific tool made by Facom designed to exactly fit the hole on the block to lock the flywheel/crank. I'd used the tool on a number of occasions and found it to work well but for some reason on this engine the size of the hole is smaller so I spent some time thinking I must be going mad when I couldn't get the tool to fit, not helping was the issue of a lack of access behind the starter motor and only just being able to view the hole from an acute angle from below. When I realised that the hole was smaller I substituted the tool with a length of copper brake pipe which in reality works very well as it can be bent to whatever shape is necessary according to the equipment fitted to the particular engine.
As I intend to keep the car for a while I bought a timing belt kit (genuine Citroen) complete with new tensioner and roller, simple you'd think, remove the old tensioner and fit the new one except that as I was tightening the securing bolt I noticed that it became very tight as if it had cross threaded so rather than force it I removed and inspected the bolt to discover that the lower thread section had some swarf attached to it
so I changed the bolt for another one exactly the same and again found the bolt tightening before the washer became pinched as the bolt was bottoming out, very strange
so I consulted Citroen Service to check that I was using the correct bolt whereupon I discovered that the bolt length had been shortened from the original specification due to the new tensioner having a recessed face compared with the original one. Thankfully I applied common sense when I found the original bolt becoming tight otherwise I'd have been in a right old spot of poo with a stripped thread on the engine block
The belt kit is version 6 so beware if carrying out this task yourself.
Further job's completed was a new seal on the hydraulic pump, then after lunch I received a very welcome visit from Jim who couldn't resist getting involved in the work despite not being dressed for working on a car
all eight sphere's were changed, the LHM drained (horrible brown colour when it was poured out) and renewed with fresh LHM, the filters cleaned and the brake system flushed through to remove as much of the old LHM as possible.
As things turned out I was very grateful for Jim being there keeping an eye on things as a few minutes after starting the engine loads of steam (or maybe even smoke) started to rise from the rear of the engine from around the coolant heater plugs causing me to think that the whole lot was about to burst into flames, at the time I was at the rear of the car removing a wheel to bleed the brakes and would more than likely have missed the dramatic development until it was too late
had Jim not been there.
Long story short here but I learned a good lesson of never taking things for granted
I've lost count of the number of Xantia's I carried out a coolant change on and had never had a problem but on this occasion a large airlock must have been trapped in the heater hose causing the heater glow plugs to overheat. Following this dramatic event I connected up my coolant header tank to give a substantial head of water to push out the airlock and found that air bubbles kept rising for an eternity and much longer than any other Xantia I'd done this job on previously including my previous HDi, I've no idea why this engine is different from the other but there you go lesson learned
As the car has only completed 49K miles and I have a number of new sphere's for non Hydractive Xantia's I decided to fit a set of those in order to have a smoother ride. I have done a huge amount of experimentation with Hydractive Xantia sphere specification and have discovered that as mileage rises, the suspension damping become less effective so whilst my VSX (35k miles) rides well on non Hydractive sphere's, by comparison my old HDi (149k) felt a little sloppy fitted with the same sphere's, so I presume that as the struts wear their damping effect reduces. On Monday evening I adjusted the ride height as the front was a little high and the rear a little low, ultimately this estate now rides very well indeed, smooooth but without hitting bump stops or oscillating so I'm one happy bunny now especially after feeling every bump in my BMW sport
When the mileage is much higher I'll fit Hydractive sphere's.
For the past three days I've used the car for work but discovered that there was a terrible groaning noise sounding very much as if there was a knackered engine mounting allowing the engine to vibrate against the body, strangely the noise was only audible/felt between 30 - 40 mph when in 4th or 5th gear and under load but no other gear's. Having examined the engine mounts and adjusted the top/suspension tower mount I had a chat with Jim who mentioned rattling brake calipers then carried out a forum search and found the answer here,
it had already been diagnosed previously by me on my last HDi and V6! "Oldtimers" must be hitting me hard these days. Doh!
I'm looking forward to being able to give the car a thorough clean and polish but with another cold snap now upon us that may have to wait for a while unless I do it in the garage at work, outstanding job's still include removing the rear brake calipers to check for corrosion between the suspension arm and caliper, remove the brake pedal spring and fit a Parrot handsfree kit. Oh and I still have the O/S/F suspension to sort out on the BMW, just as well I'm off work from tomorrow until the new year.
