Fan Clutch

Has anyone replaced their fan clutch with the ones that Oemy has listed on his website? The part numbers are GM - 15712914 or AC DELCO - 15712914. These 2 are a little less expensive than the Workhorse (W8002567).

Thanks,

Jim

Read about too many people using the non-Workhorse and having issues. I spent the money on the Workhorse version.

I watched the video and he noted that he was having cooling issues and noted the coolant temp getting too high. I would think that I would notice the absence of the unmistakable roar that accompanies the clutch engaging the fan at about 205 degrees as another key indicator to the diagnosis.

FYI, the large fan nut has left handed threads.

I must have a different model, but when I took my fan clutch off, it was the "normal" threads, righty tighty lefty loosey

If you watch Kevin's video, it will also show that as well, based on the wrench holding the fan pulley

You are absolutely correct, I was thinking back on something else I had been working on, maybe replacing my grandson's A/C condenser fan on his dodge PU. sorry

I am having overheating problems on my 8.1, I think!
Changed the radiator cap, the thermo stat, I drop and
change the coolant ever couple or 3 yrs. I have closed
off the side of the fan shroud, back flushed radiator.

I am thinking that the thermo spring in back of the fan
is NOT activation at the correct temp. As I monitor the
scan gauge.
And the fan turns hard when the engine is off, less than
a quarter turn.

Anyone have any thought on the subject?? coopcolt

The fan shouldn't be that hard to turn.

When you say back flush the radiator, do you mean internally? Have you tried clean the fins? I know a lot of guys with rear radiator DPís do this on a regular basis.

vettenyts, no I did it externally, opened up the engine cowl and
with a strong concentration of hot water DAWN. Used a weed killer
pump up container to deliver the DAWN.
Then back flush with a water hose.
I also just last yr. installed a new electric fan, one of two.

Looking for something off the wall, as I have just recently heard
the engine fan kick in, seems very erratic on just when it kicks in.

It is not as loud as the engine fan in my old 454.
Now that the weather is cooler, and wont be going to FL. till Feb.

Just trying to think outside the Box...Also installed the 180 deg. stat.
which I realize does not do anything once it goes into overheat mode.

thanks.....coopcot

Can you describe what you mean by the fan seems erratic.

If you can't hear the fan engaging then it need to be replaced

How high are your temps??

Based on your description, sounds like the fan isnít engaging like it should. Mine comes on and is loud when it does. It slows down when the engine temp comes down. I replaced mine in summer 2018 when I did the water pump.
