Vac lines
« on: 08 April 2021, 08:52:46 »

After putting everything back together I decided to have a good look at the vac lines. I'm not sure if this is right but from the brake servo the diagram is showing what looks like another pipe going straight to the front multi ram (MR) actuator on the passenger side, but the pipes from the vac tank go to the rear multi-ram and the brake servo, nothing from servo goes to any of the front MR at least directly. On the front bagpipe thingy I can see front drivers side MR valve right at the radiator, and a white pipe goes from that to the one on the back, looks like a sensor, am I right that the sensor on the back is something to do with the other MR actuator as I can't see that chamber valve thing anywhere else.

Diagram:

I don't know if I'm actually looking at, or can see, the front MR left hand actuator as on the diagram, and if it's connected up properly. I done a video that might help explain and show what I'm looking at.

Just wanting to check if this might be wired up wrong as it's been like this since I got it.

If you mean that you can't see the passenger side front multi-ram (Valve shown on drawing) it's because it's not there. The diagram is probably from a 2.5/3.0 which had Secondary Air Injection Valve on the passenger side of the inlet. This was dropped on the 2.6/3.2 engine so you won't find that if you have either of those. If you google a V6 3.0 against a 3.2 and look at the passenger side inlet you'll be able to spot the difference.  :y
Apologies if I've misunderstood what you meant.  :)

Makes sense now, the top diagram must be used from the 2.5 version even though it says for later model.

The 2.5/3.0 was fitted to the first facelift model year ;)
