cadiwa Report post Posted April 4, 2013 Has anyone had a problem with the air filter collecting water spray when driving in the rain? Share this post Link to post Share on other sites
chp007kd40 Report post Posted April 5, 2013 Yes. We have a Horizon 40DP with a side radiator and 8.9 Cummins. I see water stains on the bottom of my air filter every time I have my maint. man change it. The first time I saw this I had him disconnect the the air tube until we didn't see anymore signs of moisture stains in the lines which was about four feet. I've always commented on what a bad design the low mounted side radiator is for people like us who find themselves on grass, dirt, snow and gravel parking areas. Just saw a dusted motor in Redding with 33K miles and it was not a pretty sight, so I am very careful about who works on my last motorhome. We travel in the winter also and find the very small volcanic crushed rock they use on the roadways in icy areas stuck in the radiator. Good Luck!
