Power steering problem

[rdodd]

When outdoor temps get below about 25* my power steering don't work first thing in the morning. After a few minutes it usually starts to work. Has anyone else has this problem, and what can be done to fix it? Should fluid be changed?

Power Steering

You could try changing the fluid, possibly the wrong type has been used, try Autopar part number VU1280, available from the dealer parts department. My truck has been down to -26 C (-10 to -15 F) with a good wind chill and although the steering is a bit tighter than usual it works fine otherwise.

Hope this Helps,

That sounds like the same thing that happens to rigs with rack & pinion type steering and that is caused by wear on the aluminium parts. Basically things wear to a point that an internal leak is occurring and when things expand from the power steering fluid heating up then things work fine. This can be visual diagnosed by the silvery cast to the power steering fluid (wear particles from aluminum) . I know our trucks don't have R & P steering but the same thing could happen in the pump itself.

Mine does the same thing, but at a little lower temp. I not sure it is necessarily a problem. The owners' manual in mine mentions something about revving the engine a bit before driving when it is cold because of this. Can't hurt to change the fluid though.
