Radiator is leaking again

I've made two trips since the radiator leaked and I added the Barrs leak to it without a drop left behind.  Tonight in the driveway, it's leaking again.  I thought it was just a hose clamp, but after tightening that, it seems like it's also leaking from the end tank or core.

Looks like it's going to need a radiator.  Is the radiator something special that I need to get from FT or can it be repaired or sourced by any radiator shop that does big trucks?  I wish I had a go-to place here in Vegas.  Anyone have a suggestion?

A good rad shop could probably recore it.

The tubes are coming loose from the header plate. Depending on the radiator shop and labor to R&R it can be re-soldered by a good shop. My crane vibrated those tubes loose and a shop hot tanked it and re-soldered the tubes back to the header. Otherwise the core assembly can be replaced using your tanks.

Kieth don't forget the PO had removed the radiator for leaks. I genuinely think he wouldn't cut any corners. Would double check with him what all was done. May be under warranty too.

You can still get radiator from the orginal maker down in Corpus Christi Texas. Atlas Radiator. I can get better info tomorrow. Or ask around locally. May have a better deal. Better quality by finding a shop that can build with latest and greatest materials. Mark

Should be a metal tag on the radiator somewhere,it will have a build number,try and get that and Atlas in Corpus can give you a price and timeline,figure about $500 for shipping.
PS,Anyone heard from David in Vegas lately,the guy with the shop?

A good radiator shop is:
Bob Rondeau's Radiator Shop in Bow, NH.  As a finishing touch he flows solder around the ends of the radiator tubes for additional reenforcement.  Most recently he re-cored the radiator in our Studebaker after a whoopsie.  HIs main business is truck radiators.

Could be just the gasket on the ends. I've had great luck with an ounce of cayenne pepper into the cooling system.

In March 2019 we took our rig into Cummins/Las Vegas to have the engine valves adjusted.  At the time we had a small annoying radiator leak.  I wanted them to flush the coolant system and replace the hoses; fix the leak if possible.  They stated we don't fix radiator leaks, just replace the radiator and hoses.  Gave me an estimate for $13.6 coach bucks and wait.... they needed half down before they would proceed.  I declined their fix and later on when we were in Nac in May 2019 at FOT had the mechanics tighten all the bolts connecting the tanks to the core.  This helped, but there was still some leaking.  They then poured in some Barrs? and that stopped the leaking.  The problem with this fix, is that I cannot have the coolant system flushed and the coolant replaced for fear the leaking will start again.  I have the coolant protection and pH checked and the filter changed regularly.  Don't know how old my hoses are which is concerning.  BTW - had other issues with Cummins/LV about their service; would not return!!

I left the parking brake off on our MBZ ML320 and it rolled over our bank and into a tree. I ordered a NEW aluminum radiator (OEM) style and it was delivered for $75 about 4 months ago. The AC condenser turned out to be OK but I didn't want to take any chances so also ordered a NEW one as it was only $45 delivered. $13.6 coach bucks? I don't think that is in the cards for us. The train has come off the tracks! How can anyone stand for roadside IEDs for thousands for a tow truck, mega thousands for a radiator and even more for any internal engine failure?

At a week long Cummins school, about 50 yrs ago, I was told that after sealing cooling system leaks with products with like Bars that the system needed to be drained, flushed with water, and refilled with the coolant of your choice. The stated reason for this is that heat and air are the catalyst for the sealant to solidify and plug the leak. The theory is that a catastrophic loss of coolant could result in sealant solidification where the sun don't shine e.g. radiator tubes.

I don't think it's end tank gasket...you can see in the 2nd picture I posted that coolant looks to be coming from where the tubes meet the ends of the core.

FT says they have 2 rads on order from "their supplier", which I assume is Atlas, since May.  6 months and haven't got them, plus they want $3800 for one.

I think I'm going to try 2 more bottles of Barrs leak and see if that stops it.  If not, I guess I'll have to take it in to someone.

Keith, unless they have changed to another outfit, Foretravel's supplier is Atlas Radiator which is located in Corpus Christi. I ordered mine from them about one year ago. Foretravel used the same radiator for many years. I would think yours would be a similar price.

Complete Rad/CAC Assy (as drawn) ... $3840
Radiator ONLY ...............$2488ea
Lead time is around 6 weeks.

I had Nacogdoches Motorhome Service install my new radiator. The charge was 14 hours labor at $110 per hour for about $1600.

I attached a drawing from Atlas of my radiator.

I like your idea of trying some more Barrs. I did two treatments in one of my rigs and it cured the problem.

Unless the corrosion is beyond repair, I would locate the leak, drain the radiator, let it dry, use a wire brush to take off any rust, and then patch it with JB Weld. Use the kind that takes longest to cure.

Unfortunately, it's just over a year and not in warranty.  The shop he used is a rad repair place and will not R&R it from the coach, which would really make it difficult for me.

I called FT back to verify and their price is $3802 for JUST the radiator, not the assembly.  WOW.

Price for radiator only (from Atlas) in July was $2910 +$200 shipping to Nac.  Quoted lead time was 12 weeks.

I took mine to FOT. R&R labor was 12 hrs.  The good news was that my radiator was re-cored at the shop they use in Lufkin for $600.  While they were at it I had all the hoses replaced since they were 21 years old.

So you paid $1300 in labor and $600 for the recore.  That's about 1/2 of just the radiator.  How long was your coach at FT?

Attached is the radiator portion of my ticket from FOT.  About $2700 before the Motorcade discount.  As far as timing goes, I was having work done at Xtreme and some items from the remodel shop that were going to take a while, so I was able to just leave it and they worked it into the schedule.  Worked with Alan Hall to coordinate everything.  Mine started leaking a year ago and the Barr's did not stop it.

FT has 2 radiators on order from Atlas, that they expect in the next month or so.  I've got one earmarked for me.  Just need to figure out who to have install it.  I need one or two more things looked at as well, so I think this is a good time to have a pro dig into this coach for a minute.

Still don't understand why you are buying it from Foretravel instead of Atlas unless it is the same price or cheaper,would also have your CAC checked out now as they have to remove it to replace the radiator.
