Radiator Repair

[GregOConnor]

A member of my RV Club with a HolidayRambler series 60 had a fan come off the fan motor 200 miles out of the shop from a radiator rodding. My thinking was that the shop used the old lock washers?? they then installed a new radiator and the member asked me to check their work. I found that the fan was in backwards. After speaking with the shop tec he thinks the old fan was also in backwards but there is no way to know for sure. Quite a bit to check with the fan hose and spring clamp engineered torque. Looks like they did a good job. Did you pull the fan out the bumper or out the side? I see a bumper in one image?

I plan to do this project next month.

Rather than spend too much time trying to experiment with the location of the fan to try to get better cooling, We're just going to stay with the fan located 2/3rd inside and 1/3rd outside for the time being. We're going to run the bus up Cajon pass a couple of times to determine if the cooling is sufficient. If not, then we will experiment with the fan/shroud design and possible adding an ring to the shroud.

The last two pics will show where we decided to leave it for now.
