We just brought our 84 Eagle 10 home a few weeks back and I was wondering if the placement of the 15KW Wrico generator in the far back curb side beside the engine would have an effect on engine temperature? Does the 8V71 require cross air flow from the curb side to cool properly? The people who had converted the coach totally enclosed the generator for sound reasons and the generator shares the engines radiator. Just curious... |

Where your genset is now, used to be the A/C condensor & fan. That combination dumped more heat into the engine compartment, so your configuration reduces that. Just pay close attention to the dash temp gauge if you're running the genset and pulling a grade in summertime temperatures - and downshift appropriately to keep the beast cool, too!
The only other effect I can think of at the moment is how the hum of the genset will affect you while you're trying to fall asleep if it's running. . .
FWIW,

I assume you bought it this way??? If so, it must work. I don't know about the 8v71, but my 6v92 is a constant struggle to stay cool in the summer. I have a tool chest where the AC used to be and a door that closes back there. Last summer when I went across Nevada and Utah, it got so bad I removed the door and chest and stuck it in the bay. It helped, but didn't solve my problem. I had to turn on all my heaters in some places to scavenge heat off the engine. This helped reduce the heat load off the engine quite a bit, but it makes for some annoying discomfort in the coach. Fortunately, we had enough air conditioning to overcome the heat.
After that trip I made some mods to the radiator shroud for, hopefully, better fan efficiency. I won't know the effectiveness until next summer.
My genny is in the front bay and has its own cooling system, so the heat load isn't shared like yours. Like RJ said, just keep an eye on it next summer and hope you don't have to change anything.

That is where my genset was mounted in my 80 Eagle 10. Boxed off so that no engine air could get to the genset. The genset was plumbed into the radiator of the 8V92 which runs quite a bit hotter than the 8V71 I believe. I did install two auxiliary automotive type electric fans on the radiator with a thermostat control that turned them on at 190 degrees. The fans would also come on occasionally when parked with the genset running, so you need to do that. Unit was very quiet and I never had any complaint about noise or vibration with it being almost under the bed. Suggest you talk to Dick Wright at WRICO who is an expert in this type situation.

Thanks guys for the advice. The generator sits under our side aisle, but the noise is loud enough that my kids said they had to turn the laptop computer up to the max to hear their game. There is an electric fan mounted on the side of the radiator, but I'm not sure if it works... In a previous post, I was looking for help on the temp issue, the bus would run around 195-210, but the temp gauge for the generator stayed at or below 170. I'm thinking about getting one of those infrared temp gauges and jumping out and checking the temp on our next outing. Where's a good place to check the temp? My radiator also has an air scoop on the outside. Learning the ropes of this beast...

Brent, Again I suggest you talk to Dick Wright who built your genset. I am sure he can come up with some soundproofing recommendations. Mine was so quiet that you could not really tell it was running, from inside the bus, while I was parked.
Check out the electric fan and make sure it runs, preferably with a thermostat control. You will need this fan when parked out in the desert during hot spells.
Definitely purchase one of the infrared temperature probes. Great for checking not only the radiator but also for checking for proper tire temperature. (a low tire will run hotter than the others). The top of the radiator should be about 20 degrees warmer than the bottom I think. The temperature at the top should never be much above 190-200, 210 maximum.

Go to Harborfreight.com I just bought one of the Non-contact Laser Temp guns for $3900 by the time you get It home It cost $4800 and It workes good on my 7 |

Brent, the best place to check the engine or anything else is all over. This tool can teach you things about what's going on that you wouldn't believe. They're one of the better investments that you can make.
A long time ago, I had learned some things about our atmosphere that had surprised me. For example, when I flew out of Seattle headed to Fairbanks in the winter, the pilot announced the outside temperature at elevation as a little more that 50 below.
When we we coming into Fairbanks while it was cold, the temperature at elevation was only about 30 below. It was colder on the ground than up high.
Remembering that, I used our IR thermometer in AZ when the temperature was just warm outside and got the usual readings until I aimed it straight up into a cloudless sky. It read 50 below. It made me think of space just outside of our atmosphere.
Try one; you'll like it.
