Thank you all for the answers. The radiator was rehauled 6 months ago, this just happened after the carburetor cleaning and the distributor rehauling......this morning I replaced the coolant just to be on safe side, but the temperature is still high.....I am going to take it to the mechanic tomorrow morning. It might be the timing or running lean, or maybe both........the car is running great but engine is definitely hot. I am lucky that the mechanic is only 5 minutes away......so I can drive there.
