What is "too warm"?  Does your fan cycle on and off as you would expect?

Yes, that is the thermostat housing (where the lower radiator hose 
attached, on the block, not the head)

My feeling is, when in doubt about a t-stat, simply replace - it's cheap 
and easy.  Don't forget to have fresh coolant on hand, as you will 
probably lose quite a bit while it's out.  Though I suppose with the 
hoses off you already have.

I would imagine you are also running A/C out there, so the cooling 
system can get pretty stressed.  A good flush and fill can help it do 
its job, as can cleaning out as much of the radiator (and AC condenser) 
as possible.

Also, I believe there are two thermostat temperature settings available 
- IIRC, they are about 82 or 87 C.  You might want to try to get the 
lower one.
