I was driving home and all of the sudden my speedometer stopped working off/on sporadically. Then I was going about 40 mph and my rpms jumped up to 3 to 3 1/2. when I finally got home i heard a noise coming from under the hood and I could hear coolant bubbling as my car was overheating- but the gauge on my dash board while I was driving never indicated my car was overheating? Any ideas what the issue is? Thanks!
