spal fans and shroud

[jlat]

hello people: Youz guys remember when alradco was selling them. I bought one and I knew the mounting holes did snot line up and that was why it took so long for me to get to it. Alradco was gone when I noticed it. Others said it was a drop in but that was snot in my case..I spent most of the day on the install. Lucky there,s a bracket U can remove at the bottom of the stock fan U can use as a template for the holes. Well it's in. But to anyone with one where did U mount the relays? For now I just have em two way taped to the IC as I thought the tape would stick better to the alum. rather than the powder coat.

hello people: I moved the fan 1 1/8 from where it was as it was snot centered right. I like it better now who knows for how long.
But to youz with dual fans do they both come on when needed or does it depends on how hot it is.

My dual Spal's w/ matching shroud come on at 160* and 180*, respectively. They do a great job of cooling in better than 100* temps in the desert in AZ.

Not sure what Alradco stuff does, or if it matters.

Pretty sure it's all predicated on the ECM reading the temp and regulating the low/hi fan operation. Obviously, the relay plays an important part in the overall system, as well. It must be working properly.

hello peoples and hello TurboTG. So both of your fans come and snot related to heat. Meaning 1 comes on at 160 as U say and the other at 180.
Here's another question is a stock fan set up a 2 speed?
thanks

Stock is 2 speed that's what the big resistor is for the low speed.
Chip controls low speed turn on, A/C and intake switch around 220 degrees control high speed, and never talk about the delay relay it should be gone.
I have the Alradco radiator and stock fan both speeds work, I control high speed with switch, when the A/C worked I saw 220 on 90-100 degree days high speed on, in crappy New England traffic, on the highway usually 180. 160 stat. That's my story. Most stock baffling in place.

hello peoples: I don't think Alradco would of done anything different with the wiring to the fans, just kept them as stock would have it. But anyone with his fan and shroud combo rewire it to so the fans come on at the same time. If so what did youz do to rewire.

I remember this. There was two wires that you had to switch around to make both fans come on at the same time. I did this and it worked. Unfortunately the picture does not show up on the thread. I will try and dig it up and attach it here.

Thank you all for your replies. I do have the casper hi-lo fan switch if thats what you are talking about. Someone had jumped the pins on the harness for the alradco fan to make them turn on at once when the tstat opens. Even had a pic of which wire was re-pin to make it work.

hello X: thanks for pics. I'll need to look mine and see what I have. Can you tell me how long you have been using that setup?
