Ferrari: 328 Operating temps

Hi Ian,

For my '87 328, I see oil temp and water temp both attain peak temps of ~
190-200 after the car is full warmed up and at steady-state. Keep in mind
this is in Arizona, although actually I don't see much difference in summer
or winter. But if your winter is truly cold (our winters are warm, summers
bloody hot) then maybe my operating temp info isn't relevant for you. Do
you see a difference summer vs. winter?

I get much closer to the 195/210. If run hard for a long period of
time (very naughty speeds on nice big Euro roads) she'll push beyond
these...

I'm not enough of a mechanic to understand these things, but although
I take your point about the engine being 'designed' to run at an 'optimum'
temperature, I wonder if it is that specific, purely guessing I'd have
thought
that the temperature range in which an engine will run efficiently would
be quite wide and that being on the 'low' end of the range would be
inconsequential.

Anyway, I'm sure someone who knows more about everything will
be along in a minute...

Thanks for that...we do get wide temperature variation Summer-Winter but the
thing seems to run at more or less the same temps year round. The more I
think about it displaying all the symptoms of a stuck T'stat and there is
fairly easy test to check - just start the thing & let it idle....if water
coming to the radiator gradually its probably stuck - if its working right
the rad will stay cold for quite a while and then get hot fairly quickly as
the Stat opens. I'll be doin' that as soon as it stops snowing!

Some will say it doesn't matter within reason (which is probably where I am
more or less) but there is no doubt that running an engine in a perpetually
over-cooled state isn't that good for it - if you run it without a T'stat
you really will bugger it - you get a massivly increased flow rate, a temp
guage that barely lifts off the bottom & nasty things like cavitation in the
water pump. Things are designed & tolerances set for standard operating
temps which, for most cars I've ever seen, means a water temp of 190 or 195
(about 90 in "new money").

Mrs M's Audi has an oil temp guage on it & there is no doubt that after I
changed the T'stat on that & the water temp stabilised at 90 the oil temp
came up quite a lot from where it used to run at (Funny enough it runs at
about 90 now as well!).

On the other hand the Operating manual for the 328 does talk about ranges of
temperatures. That said the one thing it is specific about is what the oil
pressure should be at 6000 rpm & 212 deg oil temp - mine never gets anywhere
near that which further suggests its running too cool. The fact that both
oil and water temps are down points to over cooling (old/lazy T-stat) rather
than a dodgy guage or a dodgy sender I think.

Hope all is well

Doesn't get near 212, or 6000 rpm..?


If it's the latter, well, I guess Paul was right about you...

At least what I could hear over the squeaking as he applied
his 20th coat of tire black.


I agree with your stuck stat diagnosis, btw.

p.s. it's 'tyre', you colonial!
p.p.s. anyone else notice that dear 'ol Iaiaiaiaiain can't spell gauge

a quick google [just to ensure I'm not making a complete tosser of myself,
you understand] reveals that neither can many others).
p.p.p.s anyone who knows me would realise how laughable the idea of me

Yes, but at least I'm not colour blind (!)

pip pip!!

For some reason I can't see Matt's post via my news server so I googled for
it - cheeky sod (!)

....and Mr Borland, for your information, it winds round happily to 7800rpm -
which is a damn site more than you're going to see out of your impending
Plymouth Voyager !! (unless, that is, you want to be wearing your valve
gear!)
