  4. 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...

  6. Using a Unorthodox Racing underdrive Pulley on your 1.8T?

    Volkswagen Passat B5 Discussion
    I've installed the UR pulley 021410602 about a year ago with the recommended Gates belts, for the accessory belt I used the Gates K050500 and is equivalent to the EU metric 5PK1270 belt. After a couple of months I got some really bad squeeks, with the AC on it was even worse. I thought it was a...

  11. EFK & Underdrive Pulley Combo - Opinions

    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:
  12. 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

  15. Installed ECS underdrive lightweight pulley kit today.

    Volkswagen Passat B5 Discussion
    My first impressions are good. Someone had described it as if you got rid of one heavy invisible passenger. I would agree. The car revs up faster and is a bit quicker. I could not believe how heavy the stock one was compared to the ECS. At least a couple of pounds difference! I recommend getting...
