I was working on my 98 XK8 and accidentally broke this small hose. (See ATTACHED photo)



Can someone identify it ... and let me know its function?

Thanks so much!

Ron

 

Welcome to the forum, Ron. That's a vacuum hose that enables the cruise control. If possible get a piece of rubber vacuum hose from your local auto supply to patch it. Please visit the new member area and introduce yourself wen you have time.

 

Thanks so much!

I figured it had to be a vacuum line - just wasn't sure for what.

I'll finish filling out my "about" forms - and definitely introduce myself to all.

Thanks again!

If this is your ride, your coolant hoses are in sad shape. The bypass hose is swollen, the upper radiator hose is collapsing.

Just an observation.

The radiator hoses almost appear to be under vacuum. Sucked in look??????

 

Ron, FWIW, when this vacuum is compromised this will happen. Start a drive, level road or downhill , engage cruise control. All looks ok until you meet a rise in the road. Cruise control will engage to increase throttle for the uphill. Leak prevents this. Car realizes its attempts are futile, cancels and disables cruise control, displays amber warning message (I forget exact verbiage).

the cruise control refreshes when ignition is cycled off on.

I encountered this when my motor mounts needed replacement. Excessive engine movement jiggled the silencer out of the air filter box and tugged on this hose enough to pull it off.

thought you might be interested.

Must be the photo - all hoses are virtually brand new. (Less than 3000 miles on them)
Had a recent massive temperature/atmospheric pressure change which sometimes causes the hose to temporarily collapse.

But thanks!

 

Also consider replacing the coolant tank cap as it has two functions pressure and vacuum release.

Fixed the hose ... and now know what is is for!

Thanks to all for your help!

 

Good job!
