2005 C5 2,0i 16v Weekend Aut, AT oil chance

[Larsen]

Hi

I think the AT needs some new oil.

286.000 km, and i don't know the maintenace standard of the previous owners. I have driven aprox 11.000 km since i bought it last year.

C5 2,0i 16v Petrol, Weekend Aut 2005 - Chasis no. VF7**************[VIN obfuscated, can be read by forum staff]. I beleave the AT is a AL4.

When i start driving all shifts up and down are smooth, where 2>3>4 are the smoothiest. When the engine reach normal working temperature, it's starts getting much harder shifts from 1>2.

Shifts 2>3>4 are still smooth.

I'm not used to working with cars, engines or gearboxes, so if somebody could publish a how-to, and which tools to use, I would be very greatefull.

I bought 8 liters of mobil LT71141 hoping it's enough to 2 changes.

Thank you

This document does not address changing the oil, but it does give a procedure for checking the level and topping up: https://frenchcarforum.co.uk/TechDocs/A ... ration.pdf

Thanks, Xantia_v6. I'll start with topping up the oil.

This is the drain and refill procedure for you on the AL4 for the C5 MK II:

Notes:

• The gearbox must be drained when the oil is hot (60 °C minimum), to eliminate the impurities suspended in the oil.
• The oil change is partial, since the converter cannot be totally drained.

Drain & Refill

C5 MK II AL4 Oil C.PNG (79.82 KiB) Viewed 281 times

Remove: The top-up plug ( 2) The oil overflow and drainage plug (1) (Approx. 3lt of oil should flow out)

Refilling Fit the drain overflow plug (1)Tighten to 0,9 ± 0,2 daN.m. Remove the filler plug (3). Use tool [1]. Dry gearbox oil capacity : EW10 engine(5,85 litres). Oil remaining after draining: 3 litres(approx.). Quantity of oil to be replaced: 3 litres(approx.). Refit the filler plug ( 3)(equipped with a new seal)Tighten to 2,4 daN.m. Initialise the used oil counter (follow the diagnostic tool procedure).

Check the Oil Level

Prior Conditions :

• Vehicle level
• Check that the gearbox is not in downgrade mode
• Remove the filler plug (3)
• Add 0,5 additional litres of oil in the gearbox
• Apply the brakes firmly and move the lever through the various selector positions
• Gear lever in position "P"
• Engine running, At idle
• The oil temperature 60°C (+ 8°; - 2°)

Remove the oil level plug ( 2). Note: Distance of 'X' for the EW10 Engine is 48mm (which yours is)

Take note of the following conditions:
Stream of oil then reducing to a sequence of drips
Refit the oil level plug (3)(equipped with a new seal)Tighten to 3,3 ± 0,5 daN.m.

Sequence of drips or nothing

• Refit the oil level plug (2).
• Stop the engine.
• Add 0,5 additional litres of oil in the gearbox.
• Repeat the top-up procedure.
  N.B.: The level of oil is correct when the stream of oil becomes drop by drop.
  Refit the oil level plug ( 2)(equipped with a new seal)Tighten to 3,3 ± 0,5 daN.m.

Check the oil level(continued)
Refit the filler plug (3)(equipped with a new seal)Tighten to 2,4 daN.m.
Too high a fluid level can cause:

• Overheating of the fluid
• Fluid leaks

Too low a level causes destruction of the gearbox.

Thank you very much Marc, for the detailed desciption. I got the correct Mobile oil now, but need to order som new seals for the different plugs.

I'll get back with the result in a week or 2.

Thanks

hello again.. I ended up with having my garage fix it. Rodovre AutoCentrum, Provensvej, Rodovre, Denmark did a fine job and is 100% familar with the process.

Why i didn't do it my self? Well first of all it was a lack of time issue, and the i got a load roarring sound, like if the exhaust pipe was touching the chassis, wich i wasn't. It was 2 broken "suspension" to the engine!!.

It was fixed and the gearbox got 750 ml of oil, and the old lady now runs smoothly noiseless like a limo, wheater it's cold or running at working temperature.

Thank you guys for all your help.

I probably get back, next time i run into uncharted teritory...

until then have a nice summer

Lars
