Engine mounts what does N and S mean?

[Craig C]

Can anyone tell me the significance of the n and the s on the engine mounts? I assume it is not related to left and right.

North and south ? Why car are they for ? If it's for a 116 the drivers side has the extra thread for the starter motor mount

Well if you may have mistaken the 'n' for a 'D' then it may well be left & right:
D for Destra = Right HS
S for Sinistra = Left HS

Not sure if this may help?
cheers aa

It's for a 2.0 litre Alfetta GTV and I have a number of mounts, some with N and some with S embossed on the rubber and am having trouble putting the engine back in the car. When I line up one side the other is too high to bolt to  the car body.  I wasn't sure if some of the mounts might be thicker / stiffer than others.

Definitely an N on some S on the others.

The two mounts are different, intake side has a different cut out for the starter motor mount as mentioned.  Oh, you should use the starter motor mount, otherwise the starter motor cracks and breaks.

EB spares have some good pictures

Hope this helps.

As to N vs S, I always wondered too.  The great mystery.

Hi Craig

I had trouble installing my engine again recently too. I put it down to the new mounts being larger than in previous times when I had used the old mounts. I had to play with it quite a bit but once I got there it torqued down fine.

As to the letters - I have no idea, but they are definitely not swappable from side to side.

S = Scarico = Exhaust (side) 
N = nnnn no, this one's got me  = Intake (side)

I'm pretty sure what Craig is referring to is two of the same, left or right with the N or the S stamped into the rubber. I.e 2 drivers side mounts, one with N and the other with S.

[Craig C]

I got the engine in with a bit of jiggling. I guess it was a case of letting the rubber compress evenly as it went down.  So N and S was probably not relevant to the exercise, just one of those mysteries.

Craig, does the rubber seem to be of a differing density. When I was trying to riddle your question I though I came across a mount described as 'normale', I can't find it now (of course), but I wonder if the S described a harder 'sports' mount?
