Want to retrofit this to my 740 to make it quieter! Like the 240s the fan in its shroud is the loudest thing in the engine bay.
Are you wedded to factory bits? A davies craig senaor and controller and a modern fan are even quieter again than older efans.
They need to be cut down. How often do you drive with the stereo off to be able to hear it! ?
Yes some trimming is needed but it's still a good fit from what I've read. You mostly hear it when you first drive off but having driven my old 244 with and without the fan you will notice the difference.
I'm wondering if I leave the original shroud in place and replace the fan with a 14inch unit mounted on the radiator, it would still work fine.
Yes and no. I do have a spare shroud worth only cutting to make fit. Then you just install a Davies Craig fan controller kit and it should be just fine.
Is thr fan working at all times? The hub could just be on its way out as I don't notice the fam on good working ones unless it's a hot day.
I was looking at the 14 & 16in Davies Craig fan kits and wondering if I could simply install the fan with the old shroud or even leave the shroud off completely. The 16in fan would cover most of the radiator.
You need the shroud to retain cooling through the radiator. A vs v6 electric fan should fit straight in too.
