Anyone on here done it on the Mondeo 2.5T,i have done it on the Focus 2.5T and it was a pita.

They both look the same,just wondered if there were any hidden attachments on the Mondeo what you cannot see.

I've had a bash twice and gave up, I got to the point I was going to take a hammer to it.
One difference between the two i have noticed is the air snorkel on the Mondeo which runs right to left as you look at it,did that get in the way ?

I have just bought a Group A,but do you know i think its too big for the space.

Its strange but there is more room in Focus engine bay than in the Mondeo.

All the extra vacuum pipe work and the vacuum thingy that sits in front of the battery just takes up space.

Yes thats where i put the one on the Focus,but there is no way that this huge thing will go down there on the Mondeo.

You can safely remove the vacuum pump and seal the plastic hose-end

The airbox itself is the same as the focus, except for the snorkel.

The trick is to spray the mounting rubbers with some lubricant and remove the snorkel+tube first, then disconnect the ECU.

This gives you barely enough room to pull out the PITA!

Cheers for your input DG,you say the vacuum pump can be taken off,what role does the pump play in the scheme of things ?

This is the pump,what does it do.

The vacuum system for the brakebooster is connected to the inlet-plenum, the inlet-pipe and the vacuum pump.

When the engine is off-throttle , there is vacuum in the plenum.

But when you put your foot down, there is boost in the plenum...... But at the same time there is vacuum at the inlet-pipe connector. So that is the backup, so to speak.

If you brake; 99,9% of the time you don't have your foot on the gas-pedal anymore ;) , so there is always enough vacuum for the brake booster.

The vacuum pump is a backup for the backup.

Focus ST's don't have it, Focus RS doesn't even has the inlet-pipe connection, only the plenum.

Volvo removed the vacuum pump for the later s40's and v50's.

JWR removed the pump from his mondeo and never noticed any difference.

My mate disconnected the pump in his S40 because of the noise it made (broken).

So what does the pump do?..... It sucks! :p
