Re: Cooling Fan Motor failure, with fusible link failure
 

Thanks for that. Just out of curiosity, how do you know it has fresh motors, etc.?

NOS = New Old Stock. Never used or installed.

Thanks for the education.

Re: Cooling Fan Motor failure, with fusible link failure
 

Update: I installed the NOS cooling fan shroud/fan assembly a few days ago.

The trick to doing so without having to open the AC system, is to unbolt the RH side fan from the shroud, and maneuver it out through the bottom. Then the shroud and LH side fan can be brought up through the top.

My suspicion was correct -- the RH motor, which was the one that blew the fusible link, would only freewheel for about 1 to 1/2 revolutions when spun by hand. The LH motor, and the NOS motors, will spin for 7-8 revolutions before coming to a stop.

Everything buttoned back up, I now have cooler A/C at idle and less risk of overheating in traffic.

Same here. Just a couple weeks ago my secondary fan took out the link. From the looks of it, the link itself was none worse for the wear - no discoloring or scorching - and still very flexible.

In doing a little research on fusible links I read where the insulation of fusible links is designed to withstand the heat of the wire melting without melting itself and possibly catching fire.

I replaced the link and the fan motor (with a new Bosch). I too took it out from the bottom. I was surprised at how easy a job it was.

Super old post, but I was wondering if someone has a part# or replacement info on these fusible links mentioned in this thread.

Re: Cooling Fan Motor failure, with fusible link failure
 

Even if the fusible link was available as an OEM part, good luck finding one for a C4 26 years after the end of production.
However, there are generic fusible links available from multiple sources. If it were I, I would determine to gauge of the wire the fusible link is protecting and go 4 numbers higher replacement fusible link.

"Typically, a given harness segment is protected by fusible link that is four gauge numbers smaller. A 14-gauge wire would be protected by an 18-gauge fusible link".
