Overheating during idle?

I have a 1940 Chevy 350 engine streetrod. It has an AFCO aluminum radiator with an electric fan. I have had for 5 years and NEVER run over 200 degrees. In fact, I have been in several parades and NEVER run hot.

The car has sat for 1 year and I recently took to a car show. The guys said i had some white smoke coming out the exhaust (maybe valve guide leaks). So, I put in some Stop Leak. It has only helped marginally.

When I drove the car yesterday, (once in the early morning and once at night time), the temp guage read 185-190 degrees the entire time). When I stopped to show the car, during a 5 minute idle- it started puking out anti-freeze and was running close to 225 degrees...... It has NEVER done this?

As I think about, I am not sure if the fan kicked on? Normally, I can hear the fan, but during my night drive, I paid attention and did NOT hear the fan come on?

Any ideas or suggestions? THANKS!

Doc here

Check the Fan fuse, relay, and sender first. Next check to see you don't have an air bubble in the cooling system. It may be time for a flush and back flush too...If All's good check the thermostat, although, it seems to operate on the Highway.

My Bet is on the Inop Fan....
