I'm buying a new radiator from Atlas. The number is B-2358 and the cost is $2,488. Incidentally, I talked with both Foretravel and Atlas. This same radiator was used for years on all Foretravel models so if you're running an 8.3 or an M-11, you're buying the same radiator. Lead time is about six weeks.

I should add that this number supersedes the original number which is B-2148.

Is the reason for replacement interior or exterior damage?

Fin rot which is now leaking. I did not do my (as they say) due diligence when I bought this rig. Just went by what I knew from the forum. Had some surprises as a result. When I got it home I got in there and took a close look and was very flabbergasted to find fin rot with exposed tubes. No leaks, however. I've put 30,000 miles on this coach and it's never overheated but I have been uncomfortable with this all along. Time to fix it right. Cheaper to do a recore but this will give me true peace of mind.

Are you adding a fuel cooler?

Hadn't really thought about it, Bob. I was thinking about getting the CAC too ($1,352) but decided against it. From what I have read, they don't fail as a rule being aluminum with no rust issues. Anyhow, it does have a cooler sandwiched between the radiator and CAC with hydraulic lines running to it. Are we normally adding fuel coolers now?

YES. Particularly with the "insulated" location of the fuel tank, a fuel cooler if running in above 80 degree F conditions is a good idea.

Been well discussed here-- basically, add a Hayden "transmission cooler" in the return line from the engine. Be able to cover it (Dianne made one that velcro'ed in place on ours) for operation in cold weather.

Production started adding them sometime after ours. 99's? M11's?

I ate a m11 ECU on a hot high speed drive last month in Utah after 3,000 hours

$6k later.

I got a quote from the cooler people. $300 range plus shipping. Mounting kit from Foretravel separate

Make sure the CAC mounting tabs on the bottom are in good shape,had to have mine rewelded at Huffman Radiator in Sinton tx,would'nt hurt to price that radiator from them,may be a little cheaper.

Brett our coach has a small cooler hanging in front of the CAC, is that a fuel cooler or something else?
Thanks

Should be easy to trace the lines from engine to it if it is a fuel cooler.

So since I have a 1996 mechanical Bosch fuel pump, I don't need a fuel cooler?

See reply #5 yours didn't come with a fuel cooler but adding one is recomended.

Mines is mounted different but the same cooler. The plumbing for it is some what of a mystery. Out of the transfer pump body to the mystery mess to the cooler out of the cooler to the mystery block then out to the tank. Only thing I can think of is it's a thermostat of sorts, or just a bunch of fittings

I removed this assembly from mine when I put in a new Mishimoto fuel cooler, full time HD FASS UP95 lift pump, and re-plumbed the fuel cooler loop. I took it apart and the only component that isn't a fitting is a check valve of sorts. The rube goldberg assembly adds no less than five 90º elbows and all the check valve could do as far as I could tell is allow some fuel to bypass the cooler if the fuel cooler was somehow clogged. John Haygarth's 2000 ISC does not have it and other 2000 and later coaches that I have looked at do not have it either. I made a function diagram of it while figuring out how to plumb the loop without this assembly. The I/O of the Mishimoto cooler is on one end and I had to fabricate mounts. The original cooler was held on by a couple of of cable clamps. The new one has threaded bosses welded on for mounting and AN fittings for the plumbing.

Don,

Thanks for the post. I will have to check my coach out to see if Rube Goldgerg worked on mine.

It will be interesting to see if they used this assy. for the 99' ISM equipped coaches. I bet the ISM's don't have a lift pump that only runs to prime the injection pump and then becomes a passive pass through manifold along for the ride...

No lift pump for my '99 ISM or M-11 which ever it is.
