Why does my C-15 Accert run cool
I have a 2005 475 Accert that will not run up to proper temperature since the cold weather has set it. Runs at 160° driving and will climb to 175° when parked until it starts to cool down at idle. Oil temp only runs up to 120°.
My fuel mileage has dropped significantly.
In warmer weather the temps run closer to where they should be.
I have installed 185° thermostats, replaced the fan hub and tried a winter front with no change.
Is this a good question?
