Is it possible to fill the gap between the shocker insert and the tube of
the strut with a fluid such as a light oil so as to help cool the inserted
shock absorber.There is only an air gap at present which is not a good means
of dissipating heat .We get very high temperatures here so any way of
tranfering heat is good .Is this a foolish idea or does it have some merit ?

Just found out it is done can it be done with Volvo 740 shocks and using
what fluid ,an anti corrosive fluid or oil?

The only problem is keeping the fluid from draining out the holes in the
bottom. I'd just use engine oil, it won't hurt anything or evaporate.
A dedicated heat transfer fluid won't transfer heat much better, and
would probably be very expensive. That said, unless you're driving very
hard over very rough roads, you probably don't have anything to worry
about.

thanks mike I was thinking off synthetic oil as it wont take much .Should
see the variation of quotes on new shockers it was huge .If bs was fuel I
would be a happy man as same shockers at over double the price fitting was
up to three times as much as well .Interesting exercise .

I'd use silicone heatsink grease, it's sold for electronics and is a white
paste that won't dry out or drip off. I'm not sure how useful this is
though, unless you're racing the shocks generally won't overheat.
