deBooza Posted July 25, 2011 Posted July 25, 2011 Hi Car is a C5 2.2HDi manual 2002 Exclusive Estate. Yesterday attempted to do an interim service – change oil, fuel and air filters along with an oil change. Tried to get the oil filter off but couldn’t. Could get my hand to it but failed to get enough purchase to turn it. Tried to get the fuel filter off but not sure how the thing comes apart/is dismantelled. Air filter was simple but will change that when I get success with the other two. Questions are:1) Can anyone recommend a filter wrench that will do the job?2) Can someone give a description of how the fuel filter is changed – what pipes come off and how to access the filter inside?3) To drain the oil from the engine I’ve always used a vacuum pump(http://www.seamarknunn.com/cgi-bin/sh000002.pl?REFPAGE=http%3a%2f%2fwww.seamarknunn.com%2facatalog%2fpumps-toilets-tanks-equipment.html&WD=pela&PN=Sump-Pumps-Oil-Changers.html%23aPL176634#aPL176634)and taken it out of the dip stick hole. It’s worked fine in the past with previous cars. Anyone know if this method is Ok with this car? Thanks in advance, deBooza Quote
Johndouglas Posted July 25, 2011 Posted July 25, 2011 All my experience is on 2 ltr C5's, so yours might be different. My oil filter has a hexagon head on it. From memory it's a 27mm socket. Just spin it off anti-clockwise. Renew the large '0' ring before replacing. My fuel filter also has a hexagon head on it so it needs a socket. Inlet and outlet pipes need to be detached first. Press down the green tab and pull off the connector. Electrical connector also removes. The filter on our other HDI has a 'lid that is held by a screwed ring - rather like a Kilner jar. After removing the ring, the lid lifts off. It should be possible to drain oil through the dipstick hole because others do it. Personally I prefer to do it the hard way and remove the plug. Quote
paul.h Posted July 25, 2011 Posted July 25, 2011 The oil filter on the mark 1 C5 is the metal can type so any type of strap or claw type of wrench should remove it. You could even try knocking a screwdriver through it but this does not always work and could simply peel the can apart. We have one of the plastic housing types on our C3 and I find it messy and takes longer compared to the can type and you can not prefill it with oil before fastening on the car. I agree with Johndouglas on preferring not to use the dipstick tube method for an oil change, since it unlikely to remove the sludge from the bottom of the sump. My last car was a Saab 9-5 and these engines where well known for failures due to sludge build up blocking the oil pump inlet filter and required best quality synthetic oils, 6000 mile oil changes and regular sump removal to clear any sludge.

Bobster Posted July 26, 2011 Posted July 26, 2011 Hi, I wrote the following piece which was printed in The Citroenian magazine, I hope it is of use. I used a standard leather strap wrench to remove the oil filter and as is my practice tightened the new one firm hand tight; never had a problem in 40 years getting them off again. Servicing – Changing Oil & Filter; 2.2 HDiRecommended at 12,500 miles, but Haynes recommends 6,000 miles. This is fairly straightforward to do. I raised the front of the car slightly on axle stands to give room to work underneath.First, remove the undertray. This is secured by small bolts at each side and by fasteners at the front and rear. The fasteners look like screws, but you only need to turn them through 90° and then gently pull the tray down to release them.The oil drain plug is situated at the rear of the sump on the back facing vertical side and needs a 8mm Hexagonal Bit Socket (looks like an Allen Key) to fit in it and turn. Unscrew it and let the oil flow into your container, this is best done after a run with the engine still warm so that any solid matter is suspended in the oil and flows out of the engine. Whilst this is draining, remove the oil filter with a strap wrench, clean the mating face and replace it with a new one having wipe some clean oil onto the rubber seal and tighten hand tight. When the oil is fully drained, replace the drain plug with a new copper washer, refill with a quality oil (I get mine from GFS with the club discount it is very reasonable), taking care not to overfill. Start the engine, check for leaks as it warms up, if all is OK replace the undertray. The only difficulty is the position of the drain plug as it cannot be seen unless you go right underneath, and it is fiddly to replace the plug just by feel. Incidentally, when I bought the car, it had a full dealer service yet the oil went black quite quickly, so I have been changing it after about 6,000 miles, yet it still goes black; I was told that this happens with diesels. Last time I changed it, when I was reaching to put the drain plug back, I accidentally dropped the copper washer and did not notice this until I had poured the new oil in! The first time this has happened in forty years and no doubt due to the awkward position of the plug. Anyway, I decided to put a container under the plug, remove it, put the washer on and replace it before all the oil had run out! Sounds a bit hairy, yet it went so smoothly that I only lost just over a cupful of oil – almost unbelievable. The point of the story though is that the oil that came out was BLACK and was just turning to oily green as the plug went back. It therefore seems clear that the plug mounting in the rear sump wall does not allow all of the old oil to drain out, which is no doubt why new oil goes black so quickly. In my case the front of the car was raised a little so this would have aided the old oil to drain, so it might be worth pouring some flushing oil in before replacing the plug to clear the old oil out. Changing the Diesel Filter; 2.2 HDiRecommended at 25,000 miles. First remove the engine top cover (four 10mm dome head nuts) and pull it away from its clips. If the engine undertray is in place, this needs removing too. You need to unclip the electric socket and clip it out of the way, then, remove the three fuel pipes in turn by depressing the coloured bar and sliding them off. With the new filter, you should have some blanking plugs, so fit these to the pipes to prevent dirt ingress. If you do not have these, then use cling film and clip or tie the pipes out of the way. The outer, knurled rim of the filter top unscrews. I used a standard oil filter strap and found that it easily turned. Remove the filter top with the old filter and away from the car pull the filter from the top and remove the rubber sealing ring. The filter body will still contain some fuel and possibly some water at the bottom and any trapped dirt. This all needs cleaning out using cloths – but I might buy a cheap turkey baster next time to draw the fluid of. Fit the new filter seal and filter to the filter top, place it into the filter body, engage the outer screw ring so that it is not cross-threaded and screw firmly home. The filter now needs priming. The other C5s are described in Haynes and have such things as lever primimg devices, however the 2.2 HDi does not. The recommended way to prime it is to connect the fuel feed pipe to the filter then using a special pipe available from Citroen, connect the filter outlet to the return. I did not choose to purchase this pipe so I ‘loose fitted’ a suitable piece of plastic tube to the filter outlet and then ran this into an empty jamjar. The filter is simply primed by turning on the ignition;you will hear the pump work for a few seconds. Turn the ignition off and on again a few times until diesel flows from the outlet. Then turn off the ignition and reconnect the outlet and return pipes to the filter. The engine should start straight away. Check for leaks, and if all is well replace the engine cover and the undertray if this was removed. Enjoy your 2.2 HDi, best wishes, Bob H. Quote
deBooza Posted September 4, 2011 Author Posted September 4, 2011 Hi Brilliant info. Done it today and was quite straight forward. Would have been even easier if I had some wheel ramps. Thanx for the excellent info. I now have it printed out and in my folder. deBooza. Quote

Thanx for the excellent info. I now have it printed out and in my folder. deBooza. Thanks for the feedback guys. I've always tried to do what servicing I can, but when I bought the C5 three and a half years ago, I was a bit daunted, a very different kettle of fish from my BX! However, it is great to share info especially on the 2.2 HDi which is not covered by Haynes, and with dealers charging £100 an hour labour you can easily save a few bob. Enjoy your C5 experience, Best wishes, Bob. Quote
gilern Posted September 10, 2011 Posted September 10, 2011 A dog choke chain and a screw driver as leaver make for an excellent filter wrench. Quote
