Is it possible for you to take a close up pic of your temp gauge and post it here? If we can communicate an accurate range that the gauge is reading, I can have a much more informed answer for you....

What is the normal temp range these trucks should run?

Expert:  Robert R replied 1 year ago.
Radiator fins don't look too bad but it may help if you wash it out. If that doesn't help you may have a partially plugged radiator internally. With that many miles chances are good that you may be partially plugged. If this is the case you may need to have the radiator professionally cleaned or replace the radiator..
Normal temperature operating range is normally between 195 and 210. It is actually normal for temperature to be higher upon initial restarting after a short sit (5 to 15 minutes). This is because there is no airflow or coolant flow with the engine off so the higher temperature of the surrounding metal gets transferred to the coolant. When you first start it the temp can be higher. As long as the temp comes down fairly quickly after a restart, I would see no reason that hitting 230 after a very short sit could cause any problems as long as temp goes back to normal within a minute or so after restarting.. Also as long as it never goes over 212 while towing or driving under a load it would be considered normal also.
