WTB - Stock Fan Relays

[SuperSix]

Is there two?

The guts came out of the cap on mine, and got corroded.


Best offers, shipped to 33624.
Thanks!

There are two small relays and one large one.

The two small control low and high speeds.  The large one is the delay relay that turns the fan on when the key is off if the coolant temp is very high.  That is the normal one to fail as it is not sealed.  If that one failed, disconnect it and forget about it.  If it was a small one, replace it...or both.  They are relatively cheap.

Thanks, dawg.

Where are they located?

This was just in the recent Kirban's newsletter:

AVAILABLE AGAIN - THE FAN DELAY RELAY SENSOR -
  
 We last show this the original GM 1986-1987 Turbo Regal Fan Delay Relay available in limited quantities back in 2007. At that time we were selling them for $75 each.
  
 This is the largest of the 3 relays located on the 1986-1987 Turbo Regal inner driver's fender. We recently came across a source that has made them available to us again. Apparently this fan delay relay was used in another application, so this part is now available again. This reproduction is better than the GM original because it has mounted the internals in the top section of the housing so moisture no longer collects on the electronics and cause corrosion and eventually failures.
  
 PHOTO 3 - Shows both a used original fan delay relay and a new reproduction with the housing removed. You can clearly see the difference in the location of the electronics and how moisture has ruined the original fan delay relay. Because both fan delay relays are identical in size, if you want to keep your car looking original, you can carefully remove the original housing cover and install it on the new reproduction unit, so the original numbers on the housing look correct.
  
 The new reproduction ones do not have any protective grease on the terminals to ward off moisture, so we have included a small packet of dielectric grease with each one. Because of its location on the inner fender, even basic washing your car can cause moisture to seep into the fan delay relay, since it is not a sealed relay.

Thanks guys.

A few weeks ago I dug through my cache of parts and found one - all is well now.

LOVE the Racetronix harness and dual fans!

Yeah, I have dual Spal fans with the Casper harness and it runs so cool...

[Steve Wood]

I have dual Spals with the Steve Wood harness and it has been running cool for years LOL

(with no stupid delay relay)

[SuperSix]

I pretty much melted my stock harness trying to run duals off of it. Stupid, yes.

The Casper Harness does away with the relay.
