suddenly my Carat w. 2.1 WBX runs hotter than usual... not overheating but
coolant needle creeps up a bit and the fan came on more often...

I suspect the thermostat - but it's new...only 6K miles, same as the Temp2
sensor, the coolant gauge sensor, new heads, new fan resistor

what else should I check? vacuum? anything electrical?

thanks in advance for any clue...
