OVERHEATING
I think you need to go back to the day that it didn't overheat and work your way forward, troubleshooting what changed to make It overheat. There is a reason why it's doing this. You'll figure it out. Check the simple things first. Don't Over complicate the thought process. Don't change parts because you're guessing. I'd make sure you have good air flow through the radiator before I did anything else. My 2 cents. Good luck!:thumbsup:
