It is not recommended by Dodge, but it might work in an emergency.

To add power steering fluid to a Chevy Silverado 1500, first locate the power steering reservoir, which is typically found near the front of the engine compartment on the driver's side. Remove the cap from the reservoir and check the fluid level; if it's low, add the appropriate type of power steering fluid until it reaches the recommended level. Be sure to replace the cap securely after adding fluid. Always consult your owner's manual for specific details regarding your model year.
