Well I'm willing to try anything would you recommend motor rat thermostat or Mopar
Although the me has never had one since i bout it
Also I've heard about upgrading to an open system maybe like A3 core what are the benefits to an open system other than just the radiator cap

Mopar thermostat 52028186AC. Amazon has them.
Nevermind a different radiator.
The cause of your overheating could be as simple as a bad cap on the pressure bottle.
Try a NAPA 703-1396 for a better seal. Most all other replacement caps are chinese junk.
Replace the fan clutch.
