Model Affected:

Concern:

In production, the power assist steering system is now filled with Pentosin CHF 11S fluid (green in color).

General Information:

From the following VIN numbers, the power assist steering system is factory filled with Pentosin CHF 11S fluid:

As of March 25, 1996 from VIN:

99 9 TS 32 3082 Coupe
99 3 TS 34 1781 Cabriolet
99 8 TS 38 5439 Targa

Pentosin has been selected for use because of better and more uniform viscosity behavior at low ambient temperatures.

Vehicles of the model types affected produced before the above mentioned VIN numbers used ATF in the power assisted steering system. It is now permitted to use Pentosin CHF 11S in these vehicles as well.

ATF fluid and Pentosin CHF 11S fluid can be mixed. In vehicles produced before the above mentioned VIN numbers, Pentosin CHF 11S fluid can be used to top off the fluid reservoir.

The 1996 911 Turbo uses Pentosin CHF 11S fluid in the steering and hydraulic assisted clutch systems. In this system, ATF must not be mixed with Pentosin CHF 11S.

Vehicles having repairs made to the steering gear that involve loss of the steering fluid should be refilled with Pentosin CHF 11S fluid.
