Another overheating situation 63 Slant six

@Hideogumperjr
The radiator has a place for a sensor so I installed a thermostatic switch at 185
I am not liking this, is this per instruction? I would like to see the sensor on the intake manifold if possible. Placement in the radiator can have very different temps depending where the sensor is placed. Me I would find the correct radiator for your car and the stock fan blades. If you still have your old radiator you can have a new core installed and using your stock brackets. You have ask yourself just when did your heating problems start....
