Thursday, 12-09-21, Morning warm-up proceeds several minutes quicker without the mech fan, as expected, saving a cup or so of petrol and making for a comfortable ride in the chill. As soon as the car starts moving, the coolant temperature drops, the thermostat closes back up, the cooling fan switch opens as it was designed to and Gertrude moves along at temperatures between ~ 165F-200 degrees Fahrenheit, the optimum temperature window for driving a Mopar B/RB engine. I hope to spray primer the hood today before inclement weather arrives tonight, replace the hood to protect the motor from the elements AND optimize air flow around the engine.
