Engine Temperature

when under hard acceleration and then cycles between about 80 and 100
degrees when fan kicks in and out. Any thoughts? Is this normal?

sounds like youre exxy is still warming up "under hard accelleration"
if the temp is still on its way to 100C?
on my exxy, the temp does fluctuate quite a bit while idling
(stationary eg while parked) -depending on whether or not the fan is
running - ie, it goes up to 100, then the fan cuts in, drops it to 80,
the fan cuts out and so the temp begins to climb back to 100 until the
fan cuts in again....and so on it cycles... this has been the way for
both exxys ive owned.
if im cruising on the open road i think it sits around 90, but its
been awhile since mine has been off the road for the last couple of
years. 90 is what my Alfa runs at, and up a big hill it climbs
through 100...
temp should be in degrees C on an exxy, so 100 should be ok..much
over 110-115 is getting closer to boiling point, but remember the
radiator system is under pressure, so the boiling point is raised
(water only boils at 100C at natural air pressure, more
pressure=raises the boiling point)
what is the consensus folks?
if youre really worried about it, give Mal Simmonds a call at dino
enterprises and see if he can shed professional light on it. tell him
your in the exxy register, im sure hell be happy to talk.

indicate the engine running lean under acceleration thereby getting
hotter, but I am not sure that it would happen so directly as to be
observable actually while you are accelerating...
Mine basically runs between an indicated 80-90deg no matter what I am
doing, unless sitting in traffic on a hot day where it might show 95
before I switch the fan on (I have two fans, but the one hooked up to
the temp sender in the rad has never come on).

pretty close to normal.
My Euro-spec '78 1300 X has a temp gauge that reads in F degrees, with
190 being mid-scale. The car will run at approx 200 under normal
ambient temps, and will rise up to around 210 going uphill (Rimutaka
hill) pretty quickly. This is using a lot of 2nd - 3rd gear work at
full throttle, and the gauge will sit at that level until I reach the
summit (radiator cooling fans have now engaged. I fitted a 2nd fan to
be in the comfort zone!)
The engine temp will drop quickly back to just below 190 as I descend
the hill.
I consider this to be pretty normal engine temp functionality.
The only time that the temp gauge will creep up to the red portion of
the gauge is if I am driving thru heavy slow moving traffic. It is for
this reason I fitted the 2nd fan with a manual override switch on the
console. The fans will switch on automatically at around the 215 mark,
but I like to use the override switch early to keep the engine temp
below the red portion of the scale - at around 200 or so.
Hope this helps your question a bit!

heater work OK?
Run the car up to temperature and then crack the air bleed on top of the
radiator. You'll need an 8mm allen key and feel around from inside the front
boot on top of the left side of the radiator. Crack it open while the motor
is still running and wait till water starts to dribble down the front of the
radiator to the floor. If you are one a slope make sure the nose and the
left front are at the highest point.
I don't normally see my engine temperature fluctuate that much when hard
driving.
Do you hear gurgling noises in the system this can also be caused by air.
Make sure you have a good mix of anti-freeze in the system even if it
doesn't get that cold. The anti freeze helps keep all those water passages
clear and prevent corrosion. If in doubt give the system a good flush -
there are two drains on each of the undercar pipes near the front but if you
take the hoses off and get a garden hose in there it can be good idea to
blow the undercar tubes clear with clean water before putting it all back
together.
