It was 100* yesterday when it went. Had to drive about 10 miles in traffic and the one fan was able to keep my temp at 215 - 220 max. It was working overtime and although my running temp was higher than I would have liked it got me home without over heating. Unfortunately it does not appear you can buy a replacement fan so I guess it is back to the junk yard.

The electric fans take a TON of vibration and stress off the mechanical water pump to start with!
Pumps will last MUCH longer with electric fans.
Electric fans take a lot of drag off the engine in general.
Dual fans have 'Redundancy', if one quits, you don't loose the entire cooling system like you would if say, a fan clutch quit working and the fan wouldn't turn.
These fans are normally NOT failure prone!
The only failures I've seen are from crash damage, a crack you don't see when you install.
I don't know why the OP's fan came apart, but everything fails at some point, it's just a fact of life, and if you don't prepare for it, you WALK HOME.
With his 'Dual Fans', NO WALKING IN THE 100 Degree heat!
No $300 tow bill to get the vehicle home...
Unplug the 'Bad' fan and DRIVE HOME to work on it! REDUNDANCY is a WONDERFUL THING!
I honestly haven't heard of any failures like this unless the fan was cracked when they got the fan out of the salvage yard...
My 'little woman' had a Ford Taraus wagon that went 350,000 miles on the fans with NO ISSUES at all.
They are RELIABLE above all else, and the redundancy factor is a big plus!
I preach REDUNDANCY, but people think it's 'Over Kill'...
I run two fans, two fuel pumps (Second fuel pump started out as an electric transfer pump so I could fuel farm equipment... Evolved into a secondary pump for the Jeep engine when the mechanical pump quit without warning one day and I didn't want to walk home!)
I have two batteries, that lets me get home when the alternator quits without carrying a second alternator,
And it helps out with welding, winching, tools, ect.
Since I have two batteries, I have two starter relays to feed the starter.
One battery or relay can be MISSING from the vehicle and it still starts/runs just fine!
Not as 'Pretty' or as 'Sexy' as a bunch of Chrome or crap with 'Skulls' printed on them, or stuff hung on there with big name brand stickers on it,
But it keeps me from walking home
in the heat/snow and the vehicle gets a lot of work done on top of that!
Even my mechanical fan has an even
number of blades.
If one is damaged, I can break it off, and the one opposite to it off and get home...
So far, none of the 'Support Systems' to the engine have left me walking in some time (Knock Wood!
) so it's working out for me...
Can't sell it as a home game, but it works for me!
The ONLY thing I haven't figured out is how to install two WATER PUMPS!
If the water pump fails, I'm SCREWED!
That's a pretty big job to do along side the road or in a mud pit somewhere!
