Well, all went pretty well here. I'll grab some images tomorrow. The (alleged) Black Beauty ..isn't black, under interior lighting, the shroud appeared beige ..under natural lighting, it's somewhere between lime green with some florescent tint to it ..and puke yellow. This supports my theory that this is a new unit without being painted and without a warranty.
Oddities I ran into.
Before installing the fan/shroud, I removed the FIT rheostat controller and extended the fan leads. I had debated on just hooking into the terminals that were for ground and MANUAL on their controller, but didn't know what effect this may have on the SPAL controller. It's intelligent and doesn't like things that are "unright".
No problem. So I decide to test the fan before bolting it in. Red to + and black to - straight to the battery. The fan spins backwards ..or rather, is sending air in the wrong direction. No problem ...(although it was "odd") we'll (my neighbor wanted in on the fun - he has a jeep too) just reverse the leads when we connected to the controller. Well, red went to red and .. Now normally this wouldn't be a problem ..but it was darn annoying.
The wiring directions (illustrations) were simple and straight forward. The programming is a piece of cake. The only thing complicated is routing the wires and putting them in their own wire looms.
The thing performs exactly as they describe it. When you hit the low set point the fan soft starts (every time it starts, btw, it's a soft start - no slamming of some relay and full speed) and will increase in speed as the temp increases. I haven't figure out if it has a PID loop in it. I think I'll ask. It didn't appear to care how long it stayed at one speed while keeping one temp. At this point I assume that it's a direct acting proportional band (or GAIN, as it may be) without any interval (rate of deviation from setpoint) or duration (time out of setpoint)components to it.
Lots of extra features too. There are leads for a secondary fan if you use a relay. It just provides a signal when the temp reaches the HIGH setpoint. I think that they also offer a full harness that will do the same thing. There's a lead for a indicator light inside the passenger compartment.
Here's something I never saw before ..well maybe I have ..but I probably thought it was an odd photo on ebay or whatever...
What's up with my asymmetrical mechanical cooling fan? I'll try and remember to get a shot of that too. I know someone here will know all about it, but it's 5 blades ..and two are grouped together fairly close. It's not radially symmetrical. The clutch appears to be ..but that fan.
The only thing I have left to do is pull the PDC cover and tie into an ignition switched relay or vacant fuse socket.
So far the only liability is that I can hear the belt squeak ...and it's annoying.
The front of the engine sorta looks naked.
Edit: Here's the StayPuffed Marshmallow Man - bilateral symmetry
