Changing Vw hydraulic fluid extends the life of steering system components. Flushing your Vw hydraulic fluid can eliminate steering related problems caused by old Vw hydraulic fluid. You should never mix generic type hydraulic fluids with OE spec Vw hydraulic fluid. Our G00200 Vw hydraulic fluid meets the hydraulic CHF 7.1 mineral base and CHF 11S synthetic base Vw hydraulic fluid specifications.

Pentosin 11S Synthetic Mineral Base Vw hydraulic Fluid

Pentosin CHF 11S is a special proprietary synthetic mineral high performance Vw hydraulic fluid. This hydraulic fluid is designed for extended mileage interval changes. This fluid is unique in its ability to maintain consistent viscosity in extreme operating temperatures from -40°C to over 130°C.

• This is the top line Vw hydraulic fluid, especially designed for hydraulics of the highest technical requirements
• Equivalent to Vw hydraulic fluid part number G 002 000 (G002000).
• Due to its excellent features it's suitable for Vw, BMW, Mercedes Benz, Porsche, Saab, Volvo System and hydraulic suspension systems
• Equivalent to BMW hydraulic fluid part numbers 82.11.1.468.041 and 81.22.9.407.758, Porsche hydraulic fluid part number 000.043.203.33
  

Bilstein 7.1 Mineral Base Vw hydraulic Fluid

Bilstein type CHF 7.1 (equivalent to Pentosin) is a select non-synthetic mineral oil blend of Vw hydraulic fluid designed for standard mileage change intervals. All properties are similar to CHF 11S with exception of synthetic mineral oil blend vs mineral oil blend and should be changed more frequently.

• Equivalent to Vw hydraulic fluid part number G 002 000 (G002000).
• Due to its excellent features it's suitable for Vw, BMW, Mercedes Benz, Porsche, Saab, Volvo System and hydraulic suspension systems
• Equivalent to BMW hydraulic fluid part numbers 82.11.1.468.041 and 81.22.9.407.758, Porsche hydraulic fluid part number 000.043.203.33
  

Flushing And Changing Your Vw Hydraulic Fluid IS Important!

Some Vw authorities suggest you don't change your Vw hydraulic fluid. We feel this isn't logical. The Vw hydraulic pump is just one of the components having many moving parts. Internal components inside the pump and steering rack and pinion wear and mesh with one another and create finite metallic particles which contaminate the Vw hydraulic fluid. It seems only logical to perform Vw hydraulic fluid service as a part of your preventive maintenance schedule and change the Vw hydraulic fluid. We recommend changing your Vw hydraulic fluid as a first step in trying to solve hydraulic related problems such as a noisy steering pump or intermitted loss of power assisted steering. The Vw hydraulic fluid system should be flushed at your Vw timing belt intervals. Vehicles operating in hot climates or that are subjected to driving in heavy city traffic should have their Vw hydraulic fluid changed every 30,000 miles. It's good preventive maintenance, inexpensive and logical for you to change your Vw hydraulic fluid. It is much cheaper than replacing an Vw steering pump or Vw steering rack and pinion.

Can You Mix CHF 7.1 Non-Synthetic Mineral Base Hydraulic Fluid With CHF 11S Synthetic Mineral Base Vw Hydraulic Fluid?

There has been a good measure of controversy over this question. Here is what our own experience shows. Over the last decade we've had no compatibility problems mixing the CHF 7.1 non-synthetic mineral base fluid and the CHF 11S synthetic based Vw hydraulic fluid. No problems with our own vehicles and no problems with our customers vehicles. Our success in mixing the 2 Vw hydraulic fluids coincides with the Audi / Vw tech bulletin 48-89-T07 issued in November 1989. It states "The new [synthetic Pentosin 11S] and old hydraulic fluid [non-synthetic Pentosin 7.1] can be mixed if necessary ... the part number [remains] unchanged." So according to Audi / Vw, you can mix the 2 Vw hydraulic fluids. Even though the composition of the fluid changed (CHF 11S synthetic mineral oil vs CHF 7.1 non-synthetic mineral oil), Audi / Vw didn't even change the part number. Please Note: Never mix generic hydraulic fluid or other fluid with the CHF 7.1 or CHF 11S Vw hydraulic fluid (G002000). If you or someone else did, flush the Vw hydraulic fluid as described below.

How To Change Vw Power Steering Fluid For Vw Passat 1998-on Models Overview:

• Refer to the factory Bentley manual for Vw hydraulic system instructions.
• We recommend having a A.S.E. certified Vw mechanic change your Vw hydraulic fluid.
• Always wear gloves and safety goggles when handling Vw fluids.
• Never start the vehicle without Vw hydraulic fluid in the fluid reservoir.

This is a basic overview of what is involved when flushing Vw hydraulic fluid. It is not intended to replace the factory Bentley manual. Please refer to the factory Bentley manual for detailed instructions.

1. The Vw hydraulic fluid reservoir is located on the drivers side inner fender well in the engine compartment right behind the head lamp.
2. Locate the oil cooler tubing in front of the radiator for Vw hydraulic fluid. Find the rubber hose that attaches to the tubing located near the drivers side lower corner of the radiator. Disconnect the hose and drain the Vw hydraulic fluid.
3. Flush the old Vw hydraulic fluid out of the Vw steering rack and pinion. Turn the steering wheel full lock side to side about 10 times. This sequence pushes the Vw hydraulic fluid out of the steering rack and into the fluid reservoir in order for it to drain out.
4. Some models have a sleeve type filter screen inserted in the fill hole of the Vw hydraulic fluid reservoir. If it has the filter, remove it and clean it. Clean out the sediment that also exists on the bottom of the Vw hydraulic fluid reservoir.
5. Reinstall the Vw hydraulic fluid hose removed in step (2) and fill the reservoir with G002000 Vw hydraulic fluid.
6. Start the engine and let the car run for 10 seconds at a idle. Important! Do not rev the engine up. Revving the engine could cause hydraulic pump damage.
7. Refill the Vw hydraulic fluid reservoir again with G002000 hydraulic steering fluid.
8. Start the engine and let the car run at a idle turn the steering wheel full lock about 10 times from side to side.
9. Turn the engine off and top off the Vw hydraulic fluid in the reservoir.
