I just installed a new water pump...on the coach--before I did the old pump did not pump the anti freeze very well so thought the pump was gone...the new one does't pump all that well...I have an 03 W...
I keep wondering why people keep fighting trying to get that yucky pink stuff through their water lines. Post after post about the problems. Just blow everything out with a compressor. You're done. No problems. In the spring just fill your tanks and you are good to go. Use a little chlorine bleach in your first fill up. JMHO
