    i have a older dodge that has a belot driven pump under the hood for the sander and plow and it worked fine last season. I just hooked the plow and sander back up to the truck and now when you turn the switch on for the pump it screaches/hums loud. but then goes away and acts normal after the truck warms up for a bit. Could there be air in the lines maybe since they were unhooked all summer? also, all the soleinoids are hooked up seperatly on the fender. can i bleed from them? it is a western blade and swenson spreader.
  2. sounds like the belt is slipping.single belt or doubble i have a double belt system and the pump is high on motor and sometimes it takes a minuit to prim when its cold! hope thos helps.also check tank make shure level is good
