To prevent future repairs for a steering gear squeak noise (as outlined in “Squeak or Rub Type Noise when Turning Steering Wheel at Slow Speeds“), GM is recommending that the fluid be changed to DEXRON-VI automatic transmission fluid when a steering gear assembly is replaced for any reason.
Make every attempt to confirm whether the power steering system has already been converted to DEXRON-VI.
If the power steering system has original fluid, the system should be flushed and refilled with DEXRON-VI using the procedure listed below.
The recommendation to convert power steering fluid to DEXRON-VI automatic transmission fluid is for gear replacements only and not for repairs to other system components, such as pump, cooler or hoses.
The service gear shipping box will contain a tag that will identify the vehicle has been converted to DEXRON-VI. The tag should be installed on the power steering reservoir filler neck and secured with the cap.
Power Steering System Flush Procedure
Important: Due to the interface between the pinion shaft seal and the fluid, it is critical to ensure that no old fluid comes in contact with the new seal. Be sure to thoroughly flush all old fluid from the system prior to installing the new steering gear assembly.
- Raise and support the vehicle until the wheels are approximately 61 cm (24 in) off the ground.
- Place a large container under the vehicle in order to collect the draining fluid.
- Loosen the hose clamp (1) and disconnect the power steering fluid reservoir inlet hose from the power steering fluid reservoir.
- Plug the power steering fluid reservoir inlet port.
Note: This step may require 3 L (3 qt) of DEXRON-VI fluid until the draining fluid appears red.
- With the key ON and the engine OFF, turn the steering wheel fully to the left and to the right while an assistant maintains the minimum fluid level in the reservoir using DEXRON-VI Automatic Transmission Fluid. Continue until the fluid from the power steering fluid reservoir inlet hose runs red.
- Remove the plug from the power steering fluid reservoir inlet port.
- Connect the power steering fluid reservoir inlet hose to the reservoir and secure the hose with the clamp.
