have your radiator flushed

 

do a good flush and check out after-market all-metal radiators on the Internet. The Evans Coolant is worth looking into...I have it on everything, even the motorcycles as it's track legal. you could also power wash the bugs and dirt out of the radiator...you'd be surprised at what's in there!

 

Another idea is to change your ratio of antifreeze/coolant and water. If you don't have to worry about freezing then water has much better heat dissipating than the antifreeze. Make sure you use distilled water though. Make sure you radiator is getting air to it also. The A/C condenser and intercooler are in the way. I would suggest a radiator flush and make sure the other too wind blocks (intercooler and condenser) are clean. Also your grille is free for air to move through.

 

First off i would suggest geting a upgraded water pump and if your radiator hasnt been removed and cleaned its almost free to do and can effect you temps alot the other thing i would do is put 2 bottles of royal purple ice in and get a 16 psi radiator cap also i upgaded to dual 18 inch electric fans witch helped alot on my truck the other things would be bigger FREE flowing exhaust intake and thats about it
