[s-cars] FYI:Leaking coolant reservoir return pipe

[J. Khang]

Hello, everyone. This is a public service announcement
for those of you whose S-cars might suffer from a
slightly leaking coolant return hose. I remember
someone was asking about this a couple of months ago.

I've had this problem for a while and tried to fix it
by tightening the clamp first and then using plumbers'
PTFE tape. Neither worked so I finally cut the end of
the hose off and reinstalled it. No more leak.

The leak is caused by the clamped section of rubber
hose attaining a permanent set. This reduces the
maximum clamp pressure that the hose clip is able to
exert and results in a small leak when the cooling
system is pressurised. Cutting off a bit of hose
reinstates fresh undeformed hose for a good seal.

End of announcement.
