    Just wondering what is best, Dextron or the Blue Hydraulic Fluid for a Western Mark IIIa ? My buddy told me he had lots of problems with Dextron freezing in the sub zero temps, and would never still it in his pump again.

    Is there any problems with putting the blue stuff in if you previously had Dextron, since it would be next to impossible to get all of the dextron out?

    Freeze up with dextron is not an issue, that would be caused by di-hydrogen monoxide (H2O) in the system, dextron will slow the pump due to thickening, at low temps the heating and cooling effects cause the paraffins to separate causing even more problems. Replacing the dextron with a low temp. hydraulic fluid will increase the performance of your plow. The cheap blue stuff is an improvement but even better is someones quality snowplow fluid. They contain lubricants and cleaners the cheap stuff doesn't have. I've had freezing problems with the cheap blue fluid, try a name brand. they have to be better their name is riding on it and they sell on more then price. They are all compatible with the gaskets and seals in your pump.

    Try draining the unit, pull the motor off and siphon or sop up what is left in the housing.
    Then run a qt. of Meyer hydro-flush though it. Meyers Hydro-flush is compatible with everything. Drain and clean again, now fill with meyer, western, boss, or snoway's Premium hydraulic fluid.

    You're pump will run faster, draw less amperage, and be less susceptible to freeze up.

    Ditto what Basher said.:nod:

    Make sure you drain the old fluid out of the rams and hoses too.
