After my previous post entitled "Overfilled Coolant on Fiat Punto", I
have determined that as suspected there was something more sinister
behind the reason I needed to add water to the beast. Yes, it seems the
head gasket has gone.
Am going to get someone to do it next week, but was just wondering if
there was anything else worth getting done at the same time, or anything
I should ask the fella to look out for. For instance, I've seen people
suggest that its worth having the head skimmed whilst this is being
done-is this a good idea and is it expensive/what does it involve?
Also, would it be a good time to have the cam belt replaced - does it
need to be removed to do this work anyway?
Anything else anyone can think of?
It would be usual practise to have the head checked and if necessary skimmed
by an engineering firm while it is off. This should cost approx another 50
quid on the bill. It is good practise (but not vital) to take all the
valves out and reface the seats, decoke the head and renew oil seals etc.
But that may make the job uneconomic if you are paying someone else.
The cam belt has to be partially removed, so it may well be a good time to
get it replaced (unless recently renewed, of course) Get the water pump
checked and if suspect replaced.
The most common reason for head gasket failure is that the engine has
overheated (even a 'small' overheat) usually because of a minor leak
somewhere else. When too hot with no coolant in the head, the alloy head
twists and buckles , soon after, the head gasket starts to leak, usually it
is assumed that the head gasket is the primary problem, but often there is
another fault (usually a leak or failed thermostat or fan) that has caused
the initial overheat.
Cheers for the comprehensive reply. I'll get him to check for possible
causes, although from what I've read it seems that the head gaskets on
these Puntos quite commonly go at low mileage, some saying they've had
theirs go at a lot lower than the 35k that's on mine.
Out of interest, any idea what sort of cost I should be expecting from
an independant garage? The bloke doing it is a friend of my Dad so I'm
not expecting to be ripped off but was just wondering.
