Thanks for the update!

So, I decided to run it till it broke and guess what happened.....the fan turned on at 230, according to my hand held obd2 reader, all is good, thanks for the input , btw the infarred did show me it was running cooler then the obd was saying, I wasnt sure what I was pointing it at, but all is good now

so the fan has 2 red leads and one black one, one red lead is thinner than the other red and black leads, is the thinner one the one thats suppose to run the fan to cool it or is the thinner one for the a/c, ifI run 12 volts to either red lead should the fan come on ? 

Did you install the updated thermostat housing with the electrical adapter?

When you installed the updated thermostat housing, you should have disconnected the old sensor in the coolant hose elbow like this:


It is possible someone already eliminated the elbow with this new hose.

Electric Fan 

The ECM drives the electric fan via relays. A resistor is connected in the supply line for stage 1 at the electric fan for the purpose of reducing the voltage supply of the fan in stage 1. In stage 2, the system voltage is fed directly to the electric motor of the fan.

Corresponding to requirements and depending on the coolant temperature, the ECM drives the corresponding relay and thus influences the speed of the electric fan. The pressure sensor for the air conditioning system also has an influence on the drive of the electric fan.

hardtop, and I havent used a a infarred, its a new sensor, and I know they go bad, just hard to believe with all the changes I made this wont work, there is only one sensor , the one in the thermostat housing on the top, and the one thats built in the thermostat housing thats not replaceable unless you change the housing, correct?

Is your 2007 S a gen2 hardtop or a gen1 convertible?

How are you measuring the temp? an infrared thermometer would be accurate.

I have a 2007 s and I rebuilt the motor, I have changed the fan, relays,thermostat housing, temp sensor in housing and cannot get the fan to come on, I have run the engine to 220 - 230 and I get nothing, the fan comes on with the a/c , but not whenI believe its suppose to, any ideas ???
