Found my dads original 1971 duster!

Just got back from a 20 min drive. Temp is now back up at around 215. I guess that’s still too hot. It’s pretty warm here today. 27 degrees. Also, I put fuel in the car when I ran to town….and now my fuel gauge suddenly doesn’t work. Lmffffffao.
Thats it for today.
Do you guys think 215 degrees is too warm to be driving it in for its alignment? Thanks
