    if your running the correct plow fluid and its fresh n clean each season then you dont realy need this.

    the correct blue fluid is rated to pour at -76* f temp :eek: look here for universal fluid spec . i was told by delivery guy he delivers LOTS of this stuff to snow plow shops all the time. and the lift gate on his truck has it. that thing moves like its a 100* day in the dead of winter.

    so unless your in the north/south pole i dont see much need for it.

    i been plowin for years and havnt had a freeze up on the few myers and fishers with the pump unit out front.

    Appreciate the post. Last year I had a terrible time with plow freezing, using the correct blue fluid. Changed fluid several times, had the shop look at it and they changed the motor/fluid resivior gasket. Just changed fluid again for the new season and got thinking i really dont wanna go through this again.

    Do you think there is a risk of overheating the fluid with that thing? Granted it is only 10 amps, but that's just more draw on your electrical system. If you are hell bent on installing it, I would put it on a timed switch. But, if your system is properly sealed, not leaking, and clean you shouldn't have to worry about a freezing issue.

    To answer your questin put a bottle of the SAM blue fluid in the freezer for a day. Pull it out and see if it is frozen. I bet it won't be.

    You are getting water in your system or it is not being flushed fully. Fix this and the problem will go away.

    I used to have a small magentic heater I bought at the auto store and put it on the pump and it did keep things warm for sure.

    I have had the shop go over the complete plow, my thought for this would be back up, same reason we all carry tools and spare parts. If something happens in the middle of the season, middle of a storm, I can just turn this on and get out of a pinch.

    I'd do it, why not? Sure your fluid wont freeze but when its cold it wont flow as freely as it would when its warm...... Just my .02

    I checked with a couple shops around here and they said they had other people coming in with the same problem. Around here the temp kept rising and dropping causing condensation to form.

    Wouldn't that cause even more of a condensation problem? You would have a bigger temp swing

    You would think, they all said that when you drain/flush it would get it all out, not so sure about that. One shop said they had the problem on a couple brand new plows( snow dogg).

    Finding the source of the water infiltration is the big issue. Add enough water to anything and you get slush and freeze up.

    Pits in the cyls ( angle or lift ) is the biggest cause on the newer plows. Followed by quick couplers on the older plows and then by condensation thru the tanks on the steel tank plows and then on the poly tank plows.

    The internal filters on most of the plows is a fine poly screen. Boss is still using mostly a wire mesh screen of a larger mesh size. If you pull a Fisher or Western, Snow Dogg or Blizzard apart right when the problem occurs you will find a fine slush attached to the screen. It can be hard to distinguish as the filter mesh is white also but you can pick it off with your finger.

    Find the source, stop it and the problem goes away.

    With the large temp swings ( 40 - 60 degrees ) in a storm system some times you will be down to straight condensation. This is more prevalent if you put the plow in a heated garage or building on a regular basis and then head out to plow.

    Thanks for the insight. I think I got everything looked over good in the off season, will find out here in a couple days. We should get lake effect (fingers crossed)

    lets see 100 wats is like leavening your lights on all night, last time I did that I had a dead battery in the AM, and cook the oil.

    I don't see a down side to using a heater.
    Start the truck, flip the switch on and by the time you are plowing your first job the pump fluid is warmed up enough it should work good and smooth with no freezing. It might even help evaporate any water in it.
    Once you start using the pump the fluid gets warmer from constant use so there no reason to leave it on unless u have a problem. Most of us have huge alternators/twin batteries and LED lights now so if it starts freezing up then flip it on.
    Kind of a no brainier.
    I'll probably get one for my pump.

    If your using quality and correct fluid, you don't need it.

    That is even more of a no brainer... use the K.I.S.S. theory;)Thumbs Up

    Well if you get water intrusion then that's not true. Sometimes the angle cylinders will pull moisture in. ESPECIALLY if they are pitted.

    If, if moisture that is just sitting on the ram can find its way in,then
    Hyd fluid at 500-1200psi will surely be squirting oot.

    But the fluid on a one way plow ram is not on the side of the stinger.
    The fluid is on the otter side of the gland nut and packing.

    A better idea would to be to fix the worn out parts.

    Ps stop nicking them with the shovel....
