Hood release cable preemptive replacement?
« on: 18 September 2021, 03:08 PM »
Hi guys
Been thinking about this for a while...is there any value in preemptively replacing the hood release cable before it snaps on you in the middle of nowhere?
Or does this fall in the "leave well enough alone" category :o?
Cheers

The cable itself seems to be very robust, the release lever assembly tends to be the failure point.

Thanks I see references to lubing the front lock mechanism so as to remove strain on the cable.

Agreed, regularly lubricating moving parts promotes their longevity, and the weakest link fails first.

I have to agree with the keeping things lubricated and leaving well enough alone.  I've never seen a hood release cable break on a W116, either.  However, I have installed several over the years.  The reason being is that the rubber grommet that is affixed to the firewall dry rots and crumbles away.  Those grommets are no longer available separately, so the only way to get a new grommet is to buy a new hood cable, as they come with a new grommet.  But 9 times out of 10 when you remove the grommet and hood cable you'll discover rust under the firewall pad.  In addition, getting the grommet to seat correctly is a huge pain.  It's a catch 22 situation.

Thank-you for the great information.
The metal barrel came off the end of my cable ! 
Anyone have solution as to how to add something to end of cable to replace it ?

Temporary fix, use a bike yoke cable clamp.

Once affixed to the cable, you have something solid to tug on and open the hood latch.

Daniel, thanks for asking this!  I've been pondering the same question for some time, so the responses are helpful and reassuring.  FWIW, some time back I did get Uncle Kent's hood adjustment tool kit.  It does seem to make that job easier and I've gotten plenty use out of the wrenches.

Do not know what a bike yoke cable clamp is ........but will certainly try to see if this works.
 Within a few days of aquiring car I lubricated the hood latch and oiled the cable some because release was very hard to pull. Of course within just a few more openings the barrel cam of the cable.  Cable did not break, just the end that holds it in the latch !!!
Thank-you 4 the suggestion..........
