I hate to bring up this subject again but here goes.
I install a 15-4947 in my coach and went to Tampa FL from Decatur AL. As long as temp was below 90 F out side I was alright. My temperature would stay below 190 F. Once the temp went over 90 degrees outside my engine temp went over 210 with AC running. I turned AC off and slowed down to 55 MPH from 65 MPH and it dropped to 195F. So I have install a 15-4644 which I used with no over heating last summer. I have an AL radiator. By the way the circuit barker potted in my generator and it got hot in the coach ... 97F.
Last summer when my clutch fan was taken out by fan belt that came off the AC and wiped out the clutch fan, I installed a direct drive until I got home. My engine temp never when over the 185 that of my thermostat even when it was above 90F with the direct drive. I could not talk to my wife but the engine stayed cool.
I have been wondering if my carb could be a little lean and that is why I cannot use the normal clutch fan and have the engine temperature stay down.

I used to have a 15-4947 and I never ran hot and I never heard the fan, of course, Wisconsin is much cooler than the south. After it failed I replaced it with a 15-4944 and now I hear the dang fan all the time.....kind of sorry I didn't stick with the 4947 now.

Hmmm, My clutch is a 4974367, I never hear it and the Engine temps are always good even with the A/C. The receipt shows a date of 8-19-83 and cost 92.90.
Wonder why the big difference in numbers.

I had a 15-4947 when I ran hot. When the clutch engages I had a slight change in noise level. It is not much. My previous one was 15-4644 and you could hear it loud and clear when it came on. The one I just install was the old number 15-4298. They had two of them and I bought them.

It was for the Olds 403, such as in a Toronado or Custom Cruiser wagon. Not sure if that is good or bad.

Thanks Ray, I have never heard a change in the sound level during the 3000 miles that I have had the Coach. The only time the temp ever went above the normal point was at idle one morning when I let it sit for aa extended time, as soon as I increased the RPM the temp dropped like a stone.
Don't know if the clutch is working or not.

My fan clutch died last summer on the way home from vacation on a Sunday night, go figure.
I replaced it with a Delco 15-4644 Heavy Duty which supposedly locks to 90% of RPM........after our trip this past weekend, I ordered a new one, a Delco 15-4947 which supposedly runs at 65% of RPM. The heavy duty drove me nuts, was engaging whenever my temp gauge went 1 spec past the 1/4 point and it's nosier than heck. My old one we NEVER HEARD and the engine always ran cool, so I decided to step it down, am hoping it works as well as the old one. If it does I'll be selling my 15-4644 which I paid $115 for last August.

The thermal load on a cooling system varies with some factors such as
ambient air temp and relative humidity, head winds vs tail winds, load in
the coach, rolling resistance of the tires and road surface, accessories
being driven by the engine, incline or decline of terrain, driving habits of
the operator and perhaps many others. How does a restrictor in place of the
thermostat compensate for all these variables? No wonder fan cluthes cycle
on and off. Whatcha think? Jim Hupy

thermostats only make your engine hot -------once they are open, they do
nothing
they do not cool or adjust, the theory is -- if you engine never gets up to
temperature it will retain moisture, etc. Just does not happen with a GMC
( at least on the left coast ;>)
now if you want to run your engine hot -- just to run a heater --- that is
up to you.

Just to stir the pot and give you another option(and poke StevieF)
When I got my engine from Mondello, they would not warranty it unless they
put in a restrictor (not a thermostat - which can fail shut). I like it,
the engine always runs at 180 cause motorhomes don't do no city driving,
they are always hot.
so with my new / old 23 , I called them to get a restrictor for the new
engine and I asked them again and he said " We don't use any thermostats
here, they can fail"

The heavy duty drove me nuts, was engaging whenever my temp gauge went 1
spec past the 1/4 point and it's nosier than heck.

So, why not run without a stat or restrictor at all ?? Has anyone ever done a test to see what temp the engine runs with the water just free-flowing? Would there be any affect on performance or ??? for us in Wisconsin where the weather is cooler ??
Oh, and if I need heat, I don't want to be using the GMC.

thermostats only make your engine hot -------once they are open, they do
nothing
they do not cool or adjust, the theory is -- if you engine never gets up to
temperature it will retain moisture, etc. Just does not happen with a GMC
( at least on the left coast ;>)
now if you want to run your engine hot -- just to run a heater --- that is
up to you.
