random temperature fluctuations?

strange thing happened when i was driving earlier.. this is the first and only time i've ever encountered this.

I was parked up reading my book for a while, and the water temp gauge was showing 60 or so..
I started driving, and the temperature rose as normal, then it got to about 85 and began going back down again at a rate that i could literally see it going down. I was a bit shocked, so i pulled over.
The water temperature went all the way up to 90. I rev'd the engine a few times and the temp fell again as it had before.

I turned the engine off, waited a few minutes, and then started her again, and the problem has vanished since.....

anyone any ideas?


the irish country roads go round and round, round and round, round and round

........ AND I LOVE IT!

Re: random temperature fluctuations?

Agree with Belfast Bob, most likely its your stat on its way out.
