Question type: Maintenance & Repair

Hi everyone,
I have a 2002 Chevy Impala 3.8
overheating when stops at the light.
I replaced the radiator May 2016,
and i just replaced the Fan last week.
After replacing the Fan I noticed one
Fan wasn't spinning and the car started
overheating,after reading some topics
online I traced the Ground wire connected
to the Fan cleaned it and now both fans
works. Now the overheat at the light and
I feel like the Fan Vibrates.
PS:1 code came up P0108 I replaced the
Map sensor yet still vibrate and overheat.
P.S: I've been riding all winter with the
DexCool GM approved.

Need Help here.
Thank you.

Yes you are right but what about the vibrations?

All you can do for the fans is to try and secure them better, but if the vibration is from the one fan you just purchased, it may be out of balance. So I would complain and try and get another one. If the vibration is cause by the air flow, then securing it better is all you can do.

Yes the Car is above 160000 miles,no digits on the meter it goes up to 3/4 and back to half never in the red. I don't think the Car has Air trapped in the Cooling system. But the problem is the intake manifold or the PCV valve,the Car would have gave me a code?

Thank you Jim,I will definitely check it out. Another Detail but it might be a different problem I've been driving with a bad A/C Fan switch for a year now. In order to get heat or A/C in the Car the Fan speed needs to be on 3, or 4 5 the 1 and 2 don't work. 3 weeks ago the Fan started making some loud Noises. Noise
