This is the first time I have seen anything written on this subject. I checked with my new found mainjtenence shop in Sacramento and to my suprise changing the power steering fluid and filter is done fairly often on vehicles getting a lot of steering use. As with fire trucks and other city dwellers. The heat generated turns the fluid black. The next decision is do you go with dextron or motor oil. Has anyone got any recent info from Prevost as to this choice. Fire back quick if you have because I will be getting into mine this Thursday when I do the water service again. We lost too much cooling fluid along side the road when the high heat sensor was removed and changed. We did not have any extra of the correct antifreeze to replenish it. We had to resort to adding water until we reached civilization. Something to think about carrying along with your spare high heat water & Oil sensors.
Thanks for the previous info from Jim and Jon.
