Bought that new electric clutch for the engine fan.

just an update: we've gotten to use the new fan in action with some huge long climbs over a few days
of arduous driving. I can only say I'm really impressed with the fan. It comes on when it should,
does its job quickly and effectively, and then shuts off. As if that weren't enough, it's a good bit
quieter than the stock fan and seems to put much less load on the engine. With our old fan,
when it came on it sounded and felt like the transmission was dying, and it was always a huge relief
when, or IF, it would go off. You can certainly tell when the new one comes on, but it's more of a whir than a roar.
And, having battled endless bad fan clutches, we can't help but smile every time it does.
I'm controlling it via the EBL EFI computer, which has a few parameters one can set. I'll draw up a
wiring diagram, etc, when I have more time.

We've only had it a short while so can't attest to longevity, but if the build quality is any indication,
I expect it to work for the rest of our ownership of this vehicle. I would not hesitate to install
one again. I'm quite sure I've spent more over the years on crappy thermostatic fan clutches that
either never worked correctly or failed quickly than I spent on this lovely thing. And although I got
very quick at changing the fan clutch with a hot engine on the side of the road, I will not mind retiring that
particular skill... :)

The old factory set up tends to engage when you crest the hill because you lift throttle and the engine speed drops which toggles the engagement at or
near threshold. If the hill were longer more severe it would (should) eventually engage but slightly later in time. If you lift and reopen throttle
you can trick it to engage sooner if at or near engagement point. Howerver when pulling grade in the good RPM range you don't want to lift and drop
below power curve so counter intuitive. Remember the clutch is thermal but also limits power transmission and max fan speed depending on temp. If
there was a good supply of USA Delco parts this electric controled device adaptation would not have been driven by necessity. Good alternative way to
go.
As far as coming on above 45 MPH -- yes they do that if need be in severe conditions. Theory is poor hot air flow exit at speed caused by high
pressure getting up under the engine room. Back in 76 my friend had a new 76 L82 Corvette. Same issue. At cruise in hot weather the temp would creep
higher, fan would engage for about 60 secs and pull temp back to stat point. This would repeat every few minutes at highway cruise. Not sure but
perhaps same fan clutch part number? Attributed to poor natural air flow as no front grill and only bottom feeder design. Also the theory is constant
cycling at road speed works the clutch hard as there is still speed differential and heat generated in the clutch that has to be disipated by the heat
sink fins on the casting running in an already hot air stream.

Would someone post a photo of this modification. Sounds like a winter project.

Billy,
Thank you for posting the picture.
I have one in my 78 Kingsly if you want me to send you installed pictures,
and call me for more explanation.

Can you install the fan without pulling the radiator?

Of course, Jim. Send photos. I'll call in a few hours so you can explain
the to me so I can create descriptions.
Thanks

There's no need to take the radiator out. You >will< have to remove the fan shroud and modify it by cutting the hole bigger in it if you have the
newer style fan shroud. If you have the 'horse collar' it will have to go away and a new style shroud fitted. Jimmy The K has them in two pieces for
easy installation.
If, like me, you've done something unsmart like bend the new trans cooler lines a little early you may have to take them loose. If you have the stock
cooler lines, the shroud will come out if you unclip them and hold the out of the way. Once my water pump project is over, my new fan goes on.

If you have the Horse Collar, you remove the steel collar and run it
without it and nothing else to modify.
Should you have the all plastic type, you trim the lip around the round
opening about 1 1/2 " all around .
So it is not a big project .

Well, that was not actually good either, Went to your album list instead of the album itself. Try this:

for-gmc.html

To get the album instead of a 404, simply 'Copy' the url, including the second line in the copy, then 'paste'in your browser. Optionally, when the
original gives a 404 error, append 'for-gmc.html' to the end of the address line.

Tom's fan album works correctly now. If you've already viewed these photos,
to make it work in the correct order now, you'll have to clear your history
cache prior to viewing again.
I apologize for it being so difficult to get them in the correct order.

Here's our installation:
http://www.gmcmhphotos.com/photos/g7107-visco-electric-mercedes-fan-clutch.html

It was a pretty easy install. The hardest part was the wiring because I was using the EBL EFI fuel injection computer instead of Tom's setup, so took
a little more time to figure out. One of the best mods I've ever done to the coach.
