Radiator fan failure July 12, 2012, 10:02:57 pm Yahoo Message Number: 9444After reading about it here, it has happened to me. My fan failed during an exhaust break activation, taking out the fan shroud, radiator, and cracking the paint in three spots on the hood where debris cracked the fiberglass. My RV is on a 2006 C5500 chassis with the duramax diesel LLY engine, and 21800 miles. Currently down in Ocala, FL awaiting parts. I can't wait to tally this expense into my summer vacation plans. Does anyone know if my insurance policy will cover any of the damage that was not a mechanical failure, mainly the hood, radiator and shroud? I have progressive, but have not called them.Roger Quote Selected

Re: Radiator fan failure Reply #6 – July 14, 2012, 10:30:20 am Yahoo Message Number: 9453Ours failed too about 3 years ago in Southern California. Going up a steep grade towing about 6K on a trailer and about 105 degrees outside. Wiped out shroud, tranny lines and lower radiator hose but no hood damage. After towing to a truck repair in Colton, it sat there for over 6 weeks while they tried to find a new shroud. None could be found. They finally had to get GM to authorize the shop to re fabricate the existing one. Ours is a 2006 Dutchman 35' and warranty had just expired within months, had less than 20K miles on it. GM replaced the parts and our extended warranty covered the rest (except the $350 plane tickets to fly back to Cal from Phx to bring it home). We too cringe every time we go somewhere in the heat (still live in Phx, AZ) and up a grade. Good luck with yours. I would like to hear if parts are available now...From: Gary Myers To: "KodiakChassisClassC@yahoogroups.com" Sent: Friday, July 13, 2012 5:20 PMSubject: Re: [KodiakChassisClassC] Radiator fan failureMine failed about 3 years ago on the way to rally in Indiana.

Re: Radiator fan failure Reply #10 – July 14, 2012, 12:30:07 pm Yahoo Message Number: 9457Greg, it didn't. The door fell off of our fridge. I was lucky we were in Elkhart as I made contact with Jayco's service mgr and they had a new Norcold door installed on Monday after we had McCormick do the annual service.Donps. I find these fan episodes frustrating even though I had a gasser. That just shouldn't happen and GM really should be standing behind its products in cases like this. I can understand why people may travel with the fingers crossed. That is how we travel towing the Escape given the number that have burned out transmissions. Our has been towed for more than 5000 miles (Florida and back twice for starters) but you still keep your fingers crossed. Tough to hold on to the steering wheel. Quote Selected

Re: Radiator fan failure Reply #25 – July 18, 2012, 01:29:21 pm Yahoo Message Number: 9494Not sure - its a whole different assembly. Mine is electric operated clutch from what i can tell. Mine failed too!!! BUT it failed in a mode where it did not spin anymore - at only 6,000 miles. Good news you really don't need the fan unless its really hot and you are driving slow climbing a steep hill and in my case I overheated following a big rig truck taking all my wind while I was towing my Jeep forcing me into the slow lanes.Once I figured out the failure mode, let the engine cool down and started up the hill again in the fast lane at 65 MPH everything was fine.Also the fan will on on a hot day when there in a A/C call and the condenser needs to be cooled more - totally unrelated to the engine radiator.Be well, ~Victor - KI6IMKodiak Diesel Dutchmen 34H BunkhouseFrom: Dennis Bradford To: "KodiakChassisClassC@yahoogroups.com" Cc: "KodiakChassisClassC@yahoogroups.com" Sent: Wednesday, July 18, 2012 10:12 AMSubject: Re: [KodiakChassisClassC] Re: Radiator fan failureThere are millions of vehicles on the road today and the majority of them older with thermostatically controlled fans.
