got a chance to drive the car today after the thermostat replacement....runs cool driving down the road but stop and go driving and the temp rises....as soon as i drive for a little while it cools down...the electric fans are on with the a/c and come on if i let it idle without the a/c and the temp get up there...i'm thinkin the fan clutch may be bad....i let it idle with the a/c on and the temp got almost to the 110 mark...i then shut it off and checked the fan clutch...the fan still spins pretty freely...shouldn't it be pretty much locked in if the temp is nearing the boiling point....it has never boiled yet..thanks guys
