  1. Wiring EFK -- Need help wiring relay

    Volkswagen Passat B5 Discussion
    So I currently have an EFK but using a temp switch sucks. It's almost impossible to adjust, making it either on all the time or not at all. I need to replace the radiator soon anyway so I am looking to just tap into the stock fan auxiliary switch in the bottom of the radiator I currently have...
  2. Recommendation for Chicago area garage/mechanic to install EFK

    Volkswagen Passat B5 Discussion
    The other week the shaft bearing for the cooling fan exploded in my 04 Passat GLS. The failure was catastrophic as the engine compartment was showered with ball bearings and the shaft had a full inch of play from side to side. The radiator survived intact so I was able to cut off the...
  3. EFK and Underdrive Pulley What size belt?

    Volkswagen Passat B5 Discussion
    I have a Electric fan and ECS underdrive crank pulley installed. I would like to remove my fan pulley. I already have a shorter belt that I got from ECS and my tensioner is at the limit of its travel causing a slight squeak from the A/C belt not being tight enough. So, here's my question...
  4. Is the EFK still made?

    Volkswagen Passat B5 Discussion
    Like the title says, I've been looking for an Electronic Cooling Fan Conversion Kit and I can't find any for the B5.5 1.8T. I know a few guys on here have been running them and that there used to be kits available, but company that I have found stopped making them. So...do you know who still...
  5. FREE EFK (used by previous member.)

    Classified Archive
    I've had this EFK sitting for about 3-4 years now. I had one chance to use it when I replaced my belts, tensioner and water pump on my 1.8T but never got around to it. The system was used once before by HvyDrkr who has since left the community. I bought it from him in a package deal. I can...

  7. FS: Everything A4 related in my garage EFK, T3/T4, WOA clutch, leather

    Classified Archive
    I’ve been away from these forums for awhile, but I finally have enough time to get organized and sell off the old parts from my Audi A4. It was a 1998.5 Audi A4 1.8T Quattro 5-speed. I’m not going to go into a lot of detail on these parts as it would take too much time, but if you have specific...
  8. EFK How-to (aborted)...

    Volkswagen Passat B5 Discussion
    (not the EFK but the How-to) My viscous fan clutch bearing sounds like an elephant cow in heat w/emphysema. I've gleaned a lot of info from PW over the years and figured it was time to give back w/a how to on an EFK install with fan delete. As Robbie Burns would have it - the best laid plans...
  9. Calling all home brew EFK experts CF/M Q's?

    B5 Garage
    After extensive research (obviously not extensive enough!) I decided on this 16" Spal fan from SpeedwayAutos.com Having wrestled w/this PIA deal all day I can safely say that this fan won't fit without trimming (of it or the stock shroud) and I'm wondering if it will fit even then. This...
  10. How to Trigger EFK?

    Volkswagen Passat B5 Discussion
    I got a 14" Electric Fan to replace my dead/dying Viscous Fan Clutch but don't have any way of regulating its operation. Any thoughts? Any thermal sensor to hook up?
  11. Doesn't anyone sell an EFK anymore?

    Volkswagen Passat B5 Discussion
    SPP doesn't carry one (anymore) and neither does EVOMS. My viscous fan clutch bearing is dead and I figured I might as well replace with an EFK. Can't seem to find anyone selling a kit. Any leads? I know the SPP kit was a SPAL fan. Anyone know which one? 13 inch Medium Profile or High...

  13. Whats better mods for V6: Chip or EFK( Electrik Fan Kit) with Crunk Pulley?

    Volkswagen Passat B5 Discussion
    Just want to know what will give me more benefit or power gain. Thanks.
  14. New Mods: Exhaust, Rear Sway, UD Pulley, EFK

    Volkswagen Passat B5 Discussion
    I wish I was a little more scientific when it comes to modding my Passat. Instead of performing each mod individually and then evaluating the performance gains of each one, I tend to do everything in clumps. Today I got my car back from Dubwerks with a SS Techtonics down pipe, TT SS 2.5"...

  16. Install EFK on V6 with Tip

    Volkswagen Passat B5 Discussion
    When installing the Spal EFK on a V6 with Tiptronic, do the ATF lines into the radiator cooler flex enough so you don't have to remove them from the radiator? I know I have to drain the radiator (remove radiator hoses) so I can swing it enough to slip in the 14" spal fan between it and the...
  17. EFK & Underdrive Pulley Combo - Opinions

    Volkswagen Passat B5 Discussion
    Fellow CBers - I am sorely tempted with the EFK GB and also have a yet uninstalled ECS Underdrive Pulley from a past GB. Will they go together or otherwise? Your pearls of wisdom, please :bow:
  18. Anyone have EFK with Underdrive Pulley and FMIC ?

    Volkswagen Passat B5 Discussion
    Has anyone installed Electric Fan Kit with an Underdrive Pulley and FMIC? Any issues with doing this? I've currently got ECS underdrive pulley and intend getting an FMIC and wandered whether the EFK would complement these items seeing as there's a GB on at the moment. Thanks, Kos
