Condition
Important: The information contained in this bulletin applies only to the models listed. DEXRON HP fluid cannot be

Some customers may comment their vehicle is experiencing a power steering noise/whine or fluid leak from the

characteristics over the former cold temperature fluid.

During extremely low temperatures, -35°C (-31°F) or lower (usually in the -40°C/F or less range), the power steering
fluid may thicken and the power steering system pressures may rise, causing damage to various components.

To resolve this condition, replace any damaged power steering system components. Refer to Power Steering in SI
for diagnosing and repairing steering system component fluid leaks.
Flush the power steering system and refill with DEXRON HP fluid.
