I am begining to notice that my car is begining to run a bit hot. I have not driven much recently but it does go up to about 100 degrees. It seems to rise a bit more at a stop and if I let it idle awhile. I think it might be the fan clutch. What do you all think and is there something else I should consider? If it is the clutch, is it pretty easy to change or should I take it in to my local shop to be diagnosed and repaired. Thank you.
