Re: ford xe 83
You may have to move it out, and if the pulley doesnt line up you can either get a crankshaft double pulley or a gilmer drive gear set up. Al depends on how much space you have.
I have the twin au fans on a std 2 core XF radiator so they are running 90% of the time, 650hp motor to turn over on startup and run a 55 amp alternater with no dramas.
Are you running an alarm which may also be draining the system?
