I was cleaning the underside of my car with some soap and water today...

basically...washed underside of car, sprayed it off with some water...drove off and heard a creak/snap kind of sound when getting off the ramps. So I drove around the block....and when I got back, opened the hood...there was no air coming from the fan. The fan was somewhat easy to stop....but the engine was still pretty cold. Do I have a problem on hand?

I was trying to clean it up to make sure I dont have any leaks in prep for a car control clinic.
