Daughter picked us up last night in her Corsa (175k) and mentioned
that the engine management light had just come on and that the fan
stayed on for some time when she stopped off to grab some milk (and
she had only driven 1/2 mile at that point). The fan stayed on a bit
when we got home (another 1/4 mile).
She doesn't use the car very often and generally only for short
journeys when she does.
Today I put about 1l of water in it and noticed that the EML went off
after a couple of restarts, it all seemed to warm up and eventually
the cooling fan kicked in and of again. Whilst it did seem there was
quite a bit of water / water vapour coming out the exhaust (to start
with especially), there didn't seem to be much /
any sludge under the
filler cap on in the cam cover or in the coolant expansion bottle.
to the heater seems quite hot but even with the blower fan
off the outlet hose is only mildly warm so does that point to a
blocked heater matrix? Could there be trapped air in there that is
causing other issues?
I had a quick look where the hoses join the heater but I can't see how
they join / release and if I was to flush the heater, would it be
'better' to take the hoses off the other end in any case (waterpump /
If it's really blocked and won't clear, are they easy to change (a
quick Google suggests they aren't as bad as some).
Or are we looking at head gasket or worse? ;-)
It seems to start and run ok (considering the age and miles etc) and
didn't seem to overpressure the cooling system after (once warmed)
revving it a bit?
