Hello,

I seem to be having some overheating issues. The 61 I'm working on has a new 2-row original style radiator, new water pump, new hoses, and a new 180 degree thermostat. Back at the end of May I had been driving it around a local town and it didn't seem to have any problems, temperature stayed right in the middle all day. Yesterday I was driving it at a steady 40 mph and the temperature gauge pegged out fairly quick after about 4 miles. It is warmer out now since it is going on July, but I don't understand what could make it drive so well last month and now it seems to overheat so badly? I haven't really messed with anything recently.

Based on some research I did, maybe I should check the timing? Also the fuel to air ratio on the carb? I also heard that a blown head gasket could be the culprit.

Does anyone else have any leads or maybe something I'm over looking? Thanks for any help!
