cant offer any help but my 68 280se inline 6 has been climbing with the increased heat lately.

apparently it is common to have cooling issues.

I too will watch the responses.

It has been recommended to me to keep an eye on coolant, possible install an electric fan (mine doesnt have one) and possible re-core.

for the time being careful driving and monitoring can keep it under control. keeping the a/c switched off certainly helps
