Radiator fan exploded!
Hey all! Recently while traveling at around 40 mph, my fan disintegrated into 1 million pieces, destroying my air filter housing, as well as the reservoir, supplying the coolant on the lower passenger side of the radiator. The shop that I had it towed to said that it may have severed the transmission cooling lines as well as the oil cooling lines. Has anybody else had this problem? And would you happen to know how much it cost to replace it and get it back to running thanks in advance. Cheers.
Oh boy. Hard to put a price on that repair, all depends on the extent of the damage. Was there red transmission fluid on the ground? While the shop may be right, all the cooling lines are in that area, you should ask them to show you the old parts and how they were damaged. If you haven't used them before and aren't really sure how trustworthy they are, they are in an excellent position to charge you for all kinds of things you don't really need. I don't want to cast a shadow on anyone but I've seen this type of thing happen before.

Just to add to this, a few months ago a couple of guys on the P38 forum I frequent talked about having the same issue, also having a lot of collateral damage. The warning is to keep an eye on your fan for faults such as cracking etc.
On a D2/P38 I've seen a lot of worn out fan shrouds at the top. That is from the fan making contact with the shroud. It's either from an improperly installed shroud/radiator, or the motor mounts. Now if it's not rubbing then yes the fan blade itself can crack and fail as well causing all sorts of damage from cooler lines, PS lines, coolant hoses, radiator, radiator shroud, serpentine belt, and even dent the hood. Check the fan blade condition at every oil change & it's much harder to spot cracks on the black OEM fan blade vs Dorman Unit.
Ouch, this has happened to me LONG ago on a D2 and actually last year on a 1988 RRC (it took out a ton of underhood components, plastics and hoses when that happened). Sorry for your troubles.
I had it happen on a D1 as well while I was waiting for a set of SG engine mounts to test out for SG. The SG mounts never arrived, and I called it quits waiting when the fan blade caught the fan shroud, and exploded right after I did an oil change and I had the hood up checking the oil. If it wasn't for my left arm which blocked 50% of the flying debris I'm certain I'd be writing this with a damaged face & eye. I found parts of the fan blade and shroud nearly 100yd from where my D1 was parked.
I found another upper/lower shroud, gave up on SG, and slapped on some Jag engine mounts. No more issues after that & occasionally I still find small parts of the debris when mowing my yard...

That kind of failure probably hurt your water pump as well, so don't be surprised if that will also need replacing. My advise (for what it's worth) would be to ditch that clutch fan as soon as possible, and do an electric fan setup, there's a lot of benefits to it. When my fan grenaded, it also took out my air box, so I replaced it with a homemade cold air intake with a bigger filter, works great and was much cheaper than the original (search the forum here for Alex M's writeup). Check out the link in my signature for the electric fan option....
