87 rx-7 overheating
 

i have a 87 rx-7 that overheats at 55-65 mph speeds. i am new to rotary motors so i dont have a clue on where to start and what to replace... what should i start with to replace or fix?? also it is not the turbo rx-7 but i am wondering what it would cost and how much work to make it turbocharged

When was the last time you changed your rad cap? Make sure your cooling system has been purged and functioning properly.

Might want to ck/replace your t-stat.
