It has gone up just over the next gauge mark, which I think is 235. I
think that it would have kept on going if I hadn't been moving agian.
Where would the aux fan be, I looked, and haven't found one, unless it is
between the AC coils and the radiator.

Re: Heating up too much
First vote is the fan clutch. But a second and easy one is the radiator
cap, if you are not getting enough pressure your water will not hold as much
heat.

It could also be the pump impeller has worn and your not getting enough
flow.
Clutches are fairly easy. When hot they shouldn't spin easily and when
cold should spin "easier" but not fully free.
Also know the 8 runs hot and has fairly poor circulation. Installing
the 5.9 hood vents is usually good for 10-20 degrees.
