The whining noise speeds up when you give it more throttle. There is nothing going on the dash, no codes, not dropping charging needle, nothing....help please! 2. my temperature gauge just started to fluctuate from normal temp 210 then drops down to 100 then right back up to 210. When it drops down it looses some rpms then picks right back up. A friend of mine is a mechanic and he said it stumps him. It is not sending any codes or anything. Please help, I am a single mom and really dont have the money to have someone try to tinker for hours. God Bless you for any help or suggestions of things that it may be.

Have the electro viscous radiator fan clutch checked. That will need to be done by a mechanic. Sorry, not much that owners can do to them anymore!
COMMENT by babyscot on November 27, 2013
would this make the RPMs drop? Someone told me that we could replace the fan clutch ourselves, is this not true? Thanks for the tip, I really appreciate it. Also, if a mechanic has to do it is it an expensive fix? and can i run it like it is for a while until i save money to get it fixed?

I am no mechanic but what I did once wgen checking is pull out a fuse and put it back in the wrong spot it was an empty spot next to the spot where it needed to go I went and started my truck me and my dash was acting all crazy rubbing rpm's and I was not even touching the gas pedal check all your fuses and make sure they're in the proper spot and you're not missing one also add an extra light emission light lit up on my dashboard that was not their previous to me checking fuses
