    power steering fluid temperature

    Has anyone taken the temperature of their atf on the power steering.
    Went out for a run on Thursday, very hot here and after an hour or so noticed the power steering seemed to have a weired noise when on full lock. Checked oil temp when I got home and found it at 68 degrees which seemed a little high to me when the engine oil is lower than that. I'v had a garage project to fit a small cooler but not got round to it yet.

    Engine oil will run at 85+ degrees all day long, if it’s running at 68 then it’s still warming up.

    jim,

    it's not the engine oil but the power steering atf which is being questioned. Typically how hot would you expect it to get when running on a normal road.

    ATF can run WAY hotter than that. 68 degrees is little more than domestic hot water. Within reason, the temperature of hydraulic oil is not important.

    yep, aware of atf spec, but has anyone taken the temp of their ps fluid after a run.

    I've never had the need to check the temp of ATF, but some power steering pumps do make a noise when on full lock.
