Earlier today I was driving around and my car started to overheat, it only does this when I come to a stop sign....as soon as I start driving the temp gauge returns to the normal position again. I spun the 2 fans and 1 sounds funny..the one on the left side of the car spins smooth and freely...the one on the right side of the car makes a click click click sound when I spin it. So Im thinking there must be something wrong with the motor cooling fan. Is there anywhere I can troubleshoot this without buying parts that are not needed? Please help, Thanks.
