Servicing A C5 V6

[Chrisc5v6]

Good morning.

I always like to do my own servicing where i can with regard to oil and filter changes.

Never done it before on this car C5 estate V6.

I ran the car up some METAL ramps making sure it was all correctly balanced and even and stable.

placed 2 house bricks behind the back wheels added safety.

Crawled underneath remove about 10 snap screws and removed the bottom cardboard /plastic cover easier than it looks.

Removed the sump plug and drained the oil into an old paint bucket sufficient capacity as the v6 has over 6 litres of oil in it.

Left it to drain for some time started looking for the oil filter.

Never found the oil filter but identified a few other items and visually looked around.

Replaced the sump plug filled the engine with 6 litres of new oil from the top.

replaced the bottom cover.

Removed the car from the ramps gently,so has not to bump the ramps.

Removed the engine top cover and there smack bang in the middle of the engine was the oil filter inverted and unless I had a 32mm socket it wasn't coming out .

I bought of ebay a set of large sockets including the size I needed for £10 all chromed up arrived in 2 days.

Removed the oil filter replaced the rubber seal and new filter tightened it up with the new socket .

You have to be a bit careful when doing it as there are multi lines everywhere which may need gently moving out the way.

Removed 4 screws on the air filter and replaced the air filter, easy.

Total cost about £60 and not more than 2 hrs work.

I also go round and spray just about everything with WD 40 especially electrical sockets and such.

Next you will be doing the cabin filter, brake cleaning, brake fluid change, diesel filter drain (or replace depending on mileage) and that will be the complete service for another 1 or 2 years. Should save you £200 to 300 on labour costs compared to a dealer so well worth doing your self.

When I first got the car ,when I put on the a/c and it stunk to high heaven .i replaced the filter behind the air blower ,not an easy job ,requires a certain amount of brute force ,after that it smelt neutral.if I knew where the diesel filter was I would have a go .

Job for tomorrow find out where that is .

If the air con still smells it will need disinfecting. On our C5 the best way is to remove the pollen filter and then using a lance type garden sprayer in the pollen filter hole, insert the lance and spray Dettol non bleach surface cleanser on to the air con evaporator matrix so it is all covered. If too much is used it will run out of the air con drain. From the parts diagrams it looks as if the C5 X7 has a similar heater where the pollen filter is accessed in the passenger footwell. https://www.tesco.com/groceries/en-GB/products/255282067?sc_cmp=ppc*GHS%20-%20Grocery%20-%20New*PX%20%7C%20Shopping%20GSC%20%7C%20Top%20Offers*PRODUCT%20GROUP255282067*&gclid=EAIaIQobChMIvsCL7qjG1gIV7Z3tCh3yzAMXEAUYAiABEgJm8vD_BwE&gclsrc=aw.ds

 

 

The diesel fuel filter looks to be at the right back corner of the engine as you look from the front. It has 4 bolts on the lid which need removing so the filter element can be lifted out. The following is the procedure from the Citroen Service box but without the pictures which do not copy.

 

ESSENTIAL : If raising the vehicle on a lift, wheels hanging, remove the cap of the LDS fluid reservoir. Refit the cap of the LDS fluid reservoir, once you have lowered the vehicle.

1. Recommended tools

 

[1] plugs kit (-).0188.T. These usually come with a new filter if from a dealer.

[2] Degreasing product SODIMAC. To clean out the filter body but something like carb cleaner should do.

[3] Brush.

[4] Cleaning tray.

[5] Diesel substitute (kerdane-dilutine or paraffin).

[6] Blanking cover for snap-on unions 5705-T.

[7] Connector for diesel filter bleeding.

 

2. Removing

CAUTION : Keep the luggage compartment lid open.

Disconnect the battery. (This is probably not needed and I did not do this on our C5).

Remove :

• The protective panel under the engine (This is so a container can be put under the filter to drain in to - when doing our C5 I just held a cup under the end of the drain hose without needing to remove the panel under the engine)
• The engine covers
• The air cleaner (complete)
• The air inlet duct from the rear turbocharger (The procedure does not mention when to fit this and the air cleaner back).

N.B. : Place a draining tray under the engine.

Slacken the 4 bolts (4) on the filter lid.

Open the bleed screw (1). This looks to be under the pipes connected to the filter. Before doing this make sure the drain hose is in place on the filter underneath so the diesel drains through it or it will spray out.

Clean the pipe unions on the filter at "a" ; By means of tools [2], [3] and [4].

Disconnect the pipes (2) and (3).

CAUTION : When uncoupling the pipes, plug the holes ; Using the tools [6].

CAUTION : Plug the pipes on the fuel filter ; as "a" ; Using the tools [1].

Remove the bolts (4).

Remove :

• The filter cover (5) and filter element (6) assembly
• The seal (8) of the cover (5)

3. Cleaning the fuel filter

CAUTION : Do not clean the fuel filter with a cloth. Do not use compressed air.

Let the fuel in the fuel filter (7) drain out.

 

 

Unscrew nut  (12) and bolts (9, 10, 11) holding the filter body in place and then remove the filter body (7).

 

Pour the product [5] into the tray [4].

Clean the fuel filter body; Using tool [3].

Drain the fuel filter.

Dry and wipe the fuel filter using a high-precision wiper (available from Replacement Parts).

 

4. Refitting

CAUTION : Open the sachet containing the new filter element just before refitting.

 

 

Refit :

• A (new) seal (8) on the cover (5)
• The (new) filter element (6) on the cover (5)
• The filter element (6) and cover (5) assembly in the fuel filter (7)
• The bolts (4)

Remove tool [6] from pipe (2).

Connect the pipe (2).

Reconnect the battery (if this was done).

 

5. Bleeding the supply circuit

Here it uses pipes to by pass bits but probably all it needs is the normal flow pipes reconnecting and the engine switching on/off a number of times. On our C5 these by pass pipes were not needed but it has a priming pump which was used. Hence the following may not be needed to be followed.

 

Couple the female union (Ø 10 mm) of the tool[7] in place of the pipe (3) ( as "b").

Disconnect the fuel return pipe (13) and insert the union (Ø8 mm) of the tool [7] into the fuel return circuit.

Switch the engine on and off 10 times in order to fill and bleed the fuel filter.

Remove :

• The tool [7]
• The tool [6] from the pipe (3)

Couple up pipes (3) and (13).

Switch the engine on and off 2 times.

 

6. Checking the seal

Start the engine.

Check the absence of leaks.

7. Refitting (continued)

Refit :

• The engine cover
• The protective panel under the engine

8. Bleed during service (presence of water)

 

Place a draining tray under the engine.

Open the bleed screw (1). (Check the filter drain hose is in place fastened to the bottom of the filter)

Switch the engine on and off 3 times.

Close the bleed screw (1).
