RE: Cooling fans

[Tom Garcia]

I think that would be “pulls” in the case of a 74 Jensen. Look at the fan blade and notice the angle of the blades. Imagine each blade cutting through the air and moving it out of the way. As you visualize the blade moving you can see the direction the air is moved. If the blade is angled from the back to the front (from the engine to the radiator) to the left, the fan must spin counter clockwise to pull air through the radiator. If it angles to the right, it’s a clockwise rotation you are after. IIRC, the replacement Bosch fans angle to the left and spin counter clockwise. Good luck, Tom   Snip…   Whichever way pushes air throught the rad!
