Hi guys,

I think my aux fan is dead. Won't come on with AC and temp creeps when stuck in traffic. Cruising brings temp down to middle, but not lower, so I'd guess t-stat and pump ok. When I look up replacement vids, they all show fans in front of the rad. Mine is between the rad and engine. Is that replacement pretty straightforward? Remove shrouds, pull up, drop in replacement, and go? The one out front required bumper work from what I saw. Hopefully the coolant can stay in the rad and the rad can stay in the car for this.

I'm going to plug in and see if I can test it or if any codes. I'm also finding fans for my model (2004 4.4) but they look to be front of rad mounted. Are there some with fans in front and some behind rad?

Thanks in advance.
