It's a 1990 VW Scirroco radiator if that helps. The hole size is 1/2" ips nom. See 2nd pic with 1/2" PVC nipple threaded in. It would also require an o-ring or gasket to seal. Any idea's or should I head to the junk yard? TIA, Kent

Temp sensor for electric fan I believe. Should have two blades for wires to attatch. It's possible the later Scirocco had a molex connector. Looks like your wires are cut anyway.

Fan switch. Some have 1 circuit and 2 wires, some have 2 circuits and 3 wires (one speed or two). You'll need this to control when the fan runs and when it doesn't. They use either a thick paper or copper gasket (I prefer the paper one). Switches run 10-30 bucks. You'll need a wiring diagram to determine which switch and how to wire it. The wrench you need is a 29mm, but a 30mm will work.

I should have said this is a 914 conversion. Suby drivetrain w/factory Suby ECU to control the fans. I need to plug it but a sender might be the easy route.

There is a plug, but I have no idea where you'd find one. Needs to have a machined flange for the seal. You'll need to relay the fan.

I have a wiring diagram for you I can even show you which relays work best sorry, couldn't resist.

Good one. And Cap't, it does appear to have a raised flange for washer contact.

There should be a temp sensor on the motor. It seems, that would be a beter place to check the temp.
I think, I pluged the hole with a temp sensor, not wired up.

Here's a fan switch from JEGS:

Even though I have fan trigger wires from the ECU (Chevy LS1 fuel-injected conversion), I like the simplicity of this switch-triggered setup that's supplied by Renegade Hybrids.

I have dual Spal fans, and I was a little surprised at the amp draw at startup...spikes at a little over 40 amps (I know this because a 40-amp fuse lasted "a little while"). 60-amp protection, er, currently.

Yea thx but that one is ips or tapered thd. I'll need something with a washer as the Cap'n mentioned.

I just threw that switch out there as a quick example. My fan switch originally had a fiber washer that dripped a little bit, but I changed over to an O-ring seal plus some sealant and it's been great.

I was speaking of the flange on the plug that could be used there. The fan switches have that sealing area incorporated in the design. To answer the switch availability issue, the VW OE or OES switch would probably be best because it's readily available in a variety of temperature ranges, it's cheap, and it fits without fooling around. The paper gasket works fine, or you can opt for the copper washer. There's no relief for an o-ring, so that would be one of the last things I would look at for sealing the joint.

never knew they made Sciroccos in 1990 How does that fit in the frunk? Any pics?

They didn't. '89 was the last model year.

The Cap'n

88 was the last year, and that was my first brand new car. I sure miss it!

All good info though I'll stay away from the crush washer. I'm afraid it wouldn't seal well against the plastic face of the radiator. I'm glad you've retired. It gives you more time to answer questions.


Doug, Look in my build thread http://www.914world.com/bbs2/index.php?sho...=201776&hl= there are several shots of it installed. And maybe it was a Golf or Jetta. I'll have to look back. And somebody needs to set Wikipedia straight on this.......... Volkswagen Scirocco
