Does anyone know where I can get a fan for a6V92 Detroit fiberglass fan rear radiator ? Foretravel doesn't have one and the manufacturer is no longer in business. Thank you

Thank you but they could not help they only do the engines now
How about Mike at Protech Racing on our forum? He is using electric fans and might have a source for a fan or a work around.

Thank you I will try to contact him tomorrow. Surly there is a repair for this!

Good man/place to deal with and quite knowledgeable.
I bought a nylon fan for our 1989 8.2 DD a few years ago.
Another lead you might try.

Hope the info above does the trick.

How about filling in all your information for your rig? Year, model, length, engine, interior layout, build number if possible. This can really help as others with the same coach can chime in for anything you need.
Thanks,

I have done this. Exact model and engine. Have to get to the coach for records Saturday. In the meantime will search around here. This is an exact replacement blade, bolt on. Actually, did it from the top down. Had to remove bed. Know I have this stuff somewhere. May have even posted it.

Look these 2 treads up in the search engine upper right corner.

Flex o fan stopped making this fans 2 years ago none in stock.
I added part numbers to the fan thread. It may work for you , may not . I have 20 -30 hrs getting it where it is today . Buy it could be replicated in about 10 , plus whatever you want to do the the engine door.
This needs a lot of 12 V amps for sure and Im not sure how many it uses . Between the fans and the AC my solar chargers and inverters are working hard.
Suspect quite a heat load difference between a Caterpillar 3208 and Detroit Diesel 6V92.
How much torque does the DD make? How much fuel does it burn?
I believe 890 ft lb I don't know how much fuel it burns per hour
If it is 6-7 mpg than it needs more radiator than 10 liter at 9 mpg .
DRP's year was programmed for 300hp and 890 ft lbs because Allison didn't make a transmission that would handle the torque of the 350 hp and 1020 ft lbs until they came out with the 746HT. Even then, Allison's 6 speed would not handle the torque so U300 owners got stuck with the 4 speed. That's why I have to back up my driveway. 90 feet elevation change in 300 feet.
The DDEC Detroits only need the ECU reprogrammed to change the HP from 250 to 630 for marine use. Unless you have a fire dept engine serial number, Detroit HQ won't program the 6V-92TA for more than 350hp. Typical for them is 350 for the small pumpers, 440 for large and 500hp for the ladder trucks. But, the side radiator for the '92 to '94 U300 is not large enough for more HP. That's why Foretravel went from one fan in 1992 to the two fan setup in 1993 models.
Mike, our U300 has recorded exactly 8.0 mpg since new (electronic readout, was 7.9 when we bought it) and will get almost 12 mpg from our house to San Francisco. And we live in the Sierras where every drive is full throttle or Jake.
All GVs would not need any more radiator if it had been placed in the nose where it belongs.

What are the radiator measurements? for the rear setup? Sounds like it should have a larger radiator than my baby Cat 3208 .
How big is the fan ?
Thank you for all the information Pierce, 7mpg is what I get. I contacted Flex O Lite and they quit making those fans two years ago. I'm working with Josh Harsany in Detroit Mi I m hoping he maybe able to come up with something. Parts guys at Foretravel didn't have anything I have a call in to tech support also for their input. Any help is greatly appreciated!!
The fan is 28" with a 2 pilot 6 blade the radiator is 42" wide by 28 1/2 tall with 6 rows that is the core size.
Mine is 46 wide
36 tall
7 thick
That is out side of all tanks
Not core.
DRP,
If you have access to a Pro-Link 9000, you can even check the gallons your coach has used since new and the fuel mileage since new. It's also handy to see any codes the ECU has recorded. Someone will probably have one at Quartzsite. This reading is from 2013 as I remember.
Pierce
No sir I not have that
It's a good tool to have as it can diagnose any problems the same as the Detroit dealer (or Cummins, CAT, Allion, Meritor). You can find the reader/cartridge on FB Marketplace or ebay for around $100 if lucky, less than $200 if not so lucky. And others will try and get a fortune for the tool and cartridge. This is a used price as the new models are a couple of thousand $ I have the factory user manual also in PDF format. It's free to anyone interested.
If interested, send me a PM and I will try and help you find one. Attachment shows the reader from the front. only as the cartridge slides in on the back side. This works on all Foretravels with the 2 cycle engine.

Nitehawk you are the man! Josh has fan coming to me he feels like work so thank all of you guys for your help and input! We should be back on the road in a couple of weeks!! Dennis
Dennis, has the fan showed up yet??
Yes sir I received it yesterday! It looks good and is a direct replacement. It is a 7 blade versus a 6 blade but has the same pitch so it will provide a little additional cooling that will not hurt a thing!!! I little FYI to all you owners with a fiberglass blade change it!!! Thank you again Nitehawk!! The radiator will take 2 more weeks to get here it had to be made being it was a 6 row! I'm not looking forward to the reassembling it's a pretty thought job!
Ok guys what pressure radiator cap should I us? Apparently I placed mine in the wrong place and it got mashed.
6V92 Detroit 1991 Grand Ville rear radiator!
Does it have a coolant recovery bottle ? I use 9# with a bottle .
Mike , it does have a bottle so is that a 9psi cap?
The Detroit factory has 7 psi for their replacement cap. Replacement caps are available from 7 to 16 psi. After reading the Wanderlodge forum and from my experience with ours, I think that after fitting the rear and rear side radiators to many of the Foretravel models, some have experienced marginal cooling in some environments such as summer, long grades and high altitudes. Ours is no exception as it's really a three season coach for not really having to monitor the temp gauge that closely.
At 7 psi, a 50/50 mix will boil at 248 F. With a 15 psi, the same mix will boil at 265 F. Naturally, interior cylinder passages may be quite a bit higher than where the sensor is located. If the coolant does boil, it creates a partial void and less cooling occurs around locations like the exhaust valve.
I checked our OEM cap and it has the 15 psi stamp on it. Not likely that either the PO or anyone else replaced it. I think that when Foretravel installed the rear radiator in the U300, they derated the Detroit to 300 hp with a firmware change as the available Allison would not handle the torque of the 350 hp engine. So, when they went to the side radiator and 746 Allison, they updated the ECU to 350 hp in 1992 and installed the vertical single fan radiator. This was not enough and many overheated so the next year, they went to a larger horizontal radiator with two hydraulic fans. The problem is the second fan uses even more power to run and power is heat. I think this is why the 15 psi cap was OEM on ours. A stopgap measure for a poor cooling design.
In marine use, the 6V-92TA gets all the cooling it needs from the ocean or river so up to 620 hp can be squeezed from the engine with only a change to the ECU.
Even U225 members have had cooling problems with some adding an aux front radiator to better cool their engine.
Pierce
Yes. I use a 9 with the bottle. It sounds important to keep the rad full .
The coach is ready for the road again, new 7 blade fan and new radiator installed . If anyone has a fiberglass fan I strongly recommend changing it! I've driven it on a short trip all is fine. Thank all you guys for you input as the fan was a problem to find and don't rely on Foretravel for any help.
Dennis
Do you have a part number for the replacement fan?
