I have a '65 Roadster with a 300 hp small block and auto transmission. In warm weather, like summertime, the engine temp runs 200 to 210 degrees. I can't make myself believe that this is design temp for the engine. I have a stock radiator that I have had out of the car and cleaned and boiled out. The water pump seems to be doing its thing and I have a new fan clutch. It has a 190 degree thermostat in it. Is there a coolant that will help with the engine temp? I want to keep the car stock so an aluminum radiator would be like a last resort. I would appreciate any info available. Thanks for the reply. John

 

hi john,try redline water wetter,it will drop temp 20 deg,and try a 180 thermostat,that should help.and make shure your cap is in good shape,and you have no air in system.

In the 60's, they did not run that hot of thermostat. 200 degrees with a 190 degree thermostat is not uncommon. I would change to a 160 degree stat, make sure there is good airflow to your radiator and try the wetter chemical. [8D]
