I need some help guys. I have a 00 dak slt. It has been running hot for about a month now. I changed the thermostat, which was stuck, and have flushed the radiator but I am still running hot. The new t-stat I put in was a 180 deg. I have no bubbles in my resivour so I don't think it's a bad or cracked head. I never let it get so hot that it over heats. I will stop and shut down the engine if it reaches 240 deg.

 

you still mostlikely to have some air pocket in it...but as you said its been a month......id try to look @ your fan clutch and or your electric fan.....

 

Replace your fan clutch. It probably isn't engaging properly. If you have the heavy duty service group truck also verify your electric fan is working. This can be done by turning on the ac

 

You also might want to check your water pump

 

you can always give the hoses a pressure test
