Cruise Control Actuator Vacuum Hose
According to Rave the cruise control actuator is meant to have a vacuum hose.
After recently doing a head gasket change (on another thread i have going) i don't know if i've lost this, or even it it originally had one? Anyone know if i'm meant to have one, what does it actually do, and where do it connect to? Thanks |

If your car was factory fitted with cruise control then yes, you are meant to have one.
The vacuum hose carries vacuum from the vacuum pump to the actuator. The vacuum pump which you will find at the rear RH corner of the engine compartment (as viewed from the front seats). Simon

I have a diesel which has to have a vacuum pump.---I thought, like Harry, the petrol engines used the inlet manifold vacuum.---

Any photo's or previous posts with photo's would be most appreciated of what it look like.
I'm having a search now. I knew i had no hose's left over (bits and pieces) so i'm guessing the hose is still connected in the engine bay, i just need to re-connect it? |

The vacuum pump ensures that the actuator is controlled accurately to maintain the pre-set road speed. Inlet manifold vacuum wouldn't work because it is directly affected by throttle position which would be adjusted by inlet manifold vacuum which would change the throttle position which would ...... you get the picture! It would be like a howl-round (acoustic feedback) at a rock concert! Simon
