Help me fix and make $50!

may i ask was the car runs at for operating tempature on the gauge? Also what size thermostat do you have. To give me a idea as to where it is at on the gauge tell me in terms of what letter the needle points to in the word "normal"...
 
The needle points straight down the center of the A. Maybe I should figure out why my codes arent showing first. I bought this car screwed up from some cartards and turned out to be the starter solenoid. Theres no telling what they tried to do!
