Im going to put this Ford Windstar Dorman Efan replacement 4,000 cfm unit on my Champion alum rad and the JY Windstar Efan I nothed the plastic shroud large enough to clear the petcock but I think if I 90° down it would work better for ease of using the petcock, notch the shroud and have the petcock facing down out of the shroud, I don't think that cut notch would hurt airflow since it'll only be 1/2" X ? deep and wouldn't need to remove the Efan shroud to change antifreeze/water, so anyone done this? The fan thats in the car is from a JY 2003 Windstar $76, the new replacement Dorman Windstar Efan $110 to my door is the one that'll fit Dorman 630-131 ,lol I guess real question is anyone put a 90 on the petcock for ease of draining?
