Which Kit Do I Need?

The ECS Tuning 6-speed Clutch Bleeder Block is available in two kits to t a wide range of VW-Audi vehicles. The two kits are identical except for a difference in the fluid seal used to connect the hose from the clutch master cylinder to the bleeder block.

The illustration on this page shows the difference between the master cylinder hose configurations and seals. The o-ring seal used at the connection between the bleeder block and concentric clutch slave cylinder is identical in both kits, for all models listed below.

SPECIAL NOTE: Be sure to remove the old seals and install the new seals included in the kits, as shown. For kits containing a grommet seal as opposed to an o-ring for the master cylinder inlet hose, please carefully observe the installation procedure outlined on Page 5 to ensure proper fitment.

Bleed the system to remove all air. The bleeder valve contains a one-way check valve, so no special bleeding equipment is needed.

Old and New Blocks

The ECS Tuning 6-Speed Clutch Bleeder Block has features not found in the original factory-installed bleeder block. Made of black anodized aluminum with a steel bleeder screw, the ECS Tuning bleeder block will not ex or expand, and is less apt to leak.

The fluid passage inside the ECS Tuning bleeder block is larger, for less fluid restriction and faster operation of the concentric clutch slave cylinder.

By comparison, the factory original bleeder block body is plastic, with a metal bleeder insert. This design is more apt to distort from pressure and heat, and is also more prone to fluid leakage at the bleeder screw insert seal.

The internal fluid passage is narrower, creating a fluid restriction that delays slave cylinder response.

Installing the New Bleeder Block

Installing the bleeder block is the same on MKIV, MKV, and MKVI vehicles. General procedures outlined below apply to all three models.

Remove the Original Bleeder Block

1) Using a pick or small screwdriver, pull up the two metal spring clips on the original plastic bleeder block.

2) Slide the supply hose from the clutch master cylinder out of the bleeder block.

3) Slide the bleeder block o the slave cylinder tube. Discard the old bleeder block.

4) Remove the old o-rings, or o-ring and seal, depending on which hose style is used.

Install the ECS Bleeder Block

1) Install the new o-rings (or o-ring and seal) on the slave cylinder tube and inlet hose. Install a new o-ring on the slave cylinder tube.

Note: For ES2608027 please refer to Page 5 for important sealing instructions.

2) Slide the “long end” of the new bleeder block onto the slave cylinder tube. Push the new retainer clip into the grooves in the block until it snaps in place.

3) Slide the hose from the clutch master cylinder into the other end of the block. Insert the remaining retainer clip.

Grommet Seal Installation Procedure

Bleeding the System

To make bleeding the clutch hydraulic system an easy one-man job, your ECS Tuning Bleeder Block has a one-way valve built into the bleeder screw. There’s no need for power or vacuum bleeding equipment.

Here’s the procedure:

  • Remove the rubber bleeder screw cap.
  • Using an 8mm wrench, crack the bleeder screw 1/4 turn (no more).
  • Attach the clear flexible hose from a bleeder catch bottle to the bleeder screw.
  • Inside the car, push the clutch pedal to the floor by hand, then pull it up again slowly. Do this several times until the brake fluid runs clear and bubble-free through the bleeder hose.
  • Close the bleeder. Reinstall the rubber bleeder cap.
  • Check clutch operation.
