Cold Weather Power Steering Hose Upgrade Kit

2015-2020 Silverado 2500HD/3500HD and Sierra 2500HD/3500HD trucks driven regularly in extreme cold climates may require use of upgraded power steering hoses. Extreme cold may affect the pliability of the power steering hoses, leading to a possible power steering fluid leak.

If the power steering hoses need to be replaced due to extreme cold weather operation, a Cold Weather Power Steering Hose Upgrade Kit is available from the GM Accessory Group. (Fig. 18) The power steering hose upgrade replacement is a customer pay option.

The upgrade kit provides enhanced protection against power steering system leaks under cold start conditions, with extensive testing and validation at temperatures of -40˚F (-40˚C). The kit contains both booster inlet and gear inlet hoses.

For more information on the available Cold Weather Power Steering Hose Upgrade Kit, access the Accessory Information Center through GlobalConect, go to (U.S.) or (Canada), or refer to Bulletin #20-NA-006.
