The top hose went on my '98 Hyundai Accent earlier - anyone know if
they're a bog-standard size, if they can be lashed up with a normal
length of hose (there's a left hand kink as it leaves the rad), and
how much damage might have been caused driving on it ?

The temp shot up once, but I dumped heat via the internal heater -
but haven't had chance to see just how dry the rad itself is yet, it
didn't draw down the coolant from the header tank :-(

If there's any damage it's likely to have been a warping of the head (is
it aluminium? they don't like getting hot).

But hopefully there's none. Who knows? You'll find out when you replace
the hose, fill it up with coolant and run it for a few days.

a wander round a breakers might bring something similar to light, but a new
one from a dealer is the best way. Engine damage might not show at all or
might show up in a few months, cross your fingers. Question is why did the
hose go? hose failure is rare these days and it may be caused by
excessively high pressure in the system (due to head gasket failure)

I'd noticed that with my 10 year old plus BMW which has never had a hose
fail. Unlike my SD1 Rover which has had several failures (top and bottom -
but others may be originals) - even when it was less than 10 years old. Is
it down to better hose materials/design - and would replacements
incorporate these? Assuming they are new ones rather than NOS.

It's a cast iron head by the looks of it - managed to do a temporary
lash-up with a bit of plastic waste pipe, and a new one should be at
the dealers' tomorrow for me :-}

Bit of an odd one though, at the same time, my indicators have
started to work intermittently (if at all), so the next question is
"where the hell's the flasher unit?" :-}

I suspect it's under the dash somewhere in the vicinity of the
steering wheel, but i'm not sure - I can hear a contactor / relay
pulling in, just doesn't go on to flash - it affects left / right
indicators and hazards.

Yeah, got one on order thanks, it's not worth arsing around for £18 !

I can live with that, it's served me well, and this is only the
second time it's let me down - and one of those times was my fault
for not changing the battery when I knew it was knackered !

I thought that myself, but can't see any sign of water in the oil or
vice-versa yet, and the emulsion near the oil cap hasn't got
drastically worse :-}

It's getting on a bit now, it's 11 years old, so i'd expect rubber to
start perishing at that sort of age - I had a leak from the bottom
hose a while ago that seemed to resolve itself with radweld :-}

JOOI, what's the temperature rating of that plastic waste pipe? At the
pressure you might find in, say, a car's engine cooling system?

Not a sodding clue, but my dad does a bit of work for someone in a
motor factors, and asked him about getting a hose in ("main dealer
jobbie") - it was him who suggested it as a temp lash-up, so i'm
guessing he's had a fair bit of experience using it !

There's only about 1cm of "bare" pipe visible, which was enough to
allow us to cut off the split bit of hose and reconnect.

My only worry now is I didn't think it was going to be cold enough
tonight to freeze, so didn't bung any antifreeze in it until we do it
properly tomorrow...

It makes you realise how much progress has been made in the last 40 years or
so. At one time people were branded as irresponsible if they ventured onto
the M1 without a spare fan belt and a top hose!

Yep, had that conversation earlier with my dad - used to be
remarkable if a car did 60k without three refurbed engines etc.
