Folks.
My TR 3A engine is running hot at highway speeds. Generally, below 70 mph (3000 rpm) the engine runs around 190 to 195 degrees. Over 70 mph, the engine temperature goes up to between 205 and 215 degrees.
The engine was rebuilt about 1000 miles ago, the radiator has been rodded out, and the engine is using a sleeved thermostat. Timing and air/fuel mixture are fine. Air deflectors to the radiator are installed correctly.
A friend is have similar issues with his TR 3A even with a new radiator (with crank hole). He also has installed the Macy’s Garage cooling fan, not that it would have any bearing at highway speeds.
It has been suggested that perhaps the water pump is moving the coolant too fast at higher rpms, thus not allowing the coolant to hang out in the radiator long enough to bet cooled off.
Any suggestions other than drive slower?
Thanks.
Ron
