The issue covered by the bulletin involves a power steering noise/whine or fluid leak from the power steering pump, gear or high pressure side power steering hose during extreme low outdoor temperature operation.
GM has determined that in extremely low temperatures, -35°C (-31°F) or lower (usually in the -40°C/F or less range), the power steering fluid may possibly thicken, causing the power steering system pressures to rise and damage various components.
To resolve the problem, GM recommends replacing the damaged components and flushing the entire power steering system with DEXRON HP ATF fluid.
GM cautions that the DEXRON HP ATF flud must be used in these vehicles thereafter and may NOT be used in any vehicle not listed above.
DEXRON HP ATP Part Number 19300536 32 oz.
