For the 5.9, in city driving, you're really playing with fire (pun

(probably the highest-CFM electric around) from his 5.2L 2WD because it
wasn't cooling well enough in his summer city driving in New Jersey. I
haven't had any problems with that fan (bought it from him) on my 5.2L
4WD in the month I've had it installed. Time will tell.
