Hey this might be wrong section, but I have a 06 lly. This truck has 210,000 miles and I have hardly ever had fan clutch lock up. Now it can be 80 degrees and it will come on a good bit. Even noticed it would come on going 75 on interstate. It will run for couple min and cut off. Temp doesn't seem to be high but not sure how accurate gauge is? Any advice? New fan clutch?
