Title: Manual Gearbox 3.0 Oil change
Post by: JamesV6CDX on 25 June 2007, 14:46:30
Questions -

Where is the drain plug

Where is the filler

What's the capacity

What type of oil to use

Any other useful tips!

Going to treat the estate to a gearbox oil change, once I sort out the oil leak...

Do you change the oil in a manual Gear Box I thought you never had to. As it not like an Auto Box

Lets See How Wrong I am lol

Its worth considering....

The drain plug is on the bottom at the rear, the level plug is on the drivers side.

Drain the oil and then fill with about 1 litre until the oil is 8mm (from memory) below the level plug......then drive it a bit and drain the oil again, re-fill as before and then its job done.

You need to do the first stage on earlier cars to flush the old stuff out which is different to the latest oil.

And the oil is Vx only......its NOT ordinary hypoid!

just drained mine.  It had exactly 1.2 litres.  So I topped up with exactly the same amount for the flush fill.  

I haven't drained to refill again yet so I do not know how close that is to being 8mm below the fill hole.  However, when I do refill I will measure it again as a rough guide for all here.

Oil - VX


Filling:  I recommend getting about 1 metre of clear plastic tube (12mm) plus a funnel.  Made refilling very easy: without that a complete PIA.

Drain and fill plug is 9mm hex

Dont forget to clear the crap of the magnet in the drain plug
