Possible Radiator Replacement??

Our '05, 40' FDTS is at the local Cummins shop in Reno, Nevada. I had a low coolant warning light. I just got a call saying the rad. is leaking around the header. He won't know if it is rebuildable or fixable until it is removed. We have some good rad. shops here. He said it is about 16 hours to remove and replace.
What luck has anyone had with repairing vs. replacing the radiator? If replacement is the better option, where do I find a replacement? Was this rad. made specifically for Alpine?
Any input is greatly appreciated. I want to do the repair correctly and do not want to cut corners. Yes, I know my checkbook will not like it, but I want to do the right thing. I imagine all rubber hoses should be replaced.
As an afterthought, are there any specific items that should be serviced or checked on the engine while it is at Cummins? It has about 50K miles on it.
Thanks a bunch!!

Hello Wrinklemeist, Sorry to hear about the radiator. If you find a radiator shop that can fix it they can build you a new one.

I would also have them check the Charge Air Cooler while it is out. If it leaking have it repaired so you do not have to pay the R&R twice. :thumbup:

Having the cooling hoses is a great idea.

Thanks for the info. I have heard of the charge air cooler but have no idea what it is or what it does.

We had our radiator replace by Quinn Cat in Calif. The Steel and Copper radiator was shipped of Sweet Home, Oregon at a cost for parts and labor $5400 with a coolant flush and Cat coolant.
Mine being an aluminum radiator it could not be fixed. You might give these guys a call to see if they have anything in stock for your coach if you need one.

A simple search of this forum will give you hours worth of reading on this topic. Bottom-line: Alpine and several other coach builder used aluminum radiators with epoxy seals/seams for a period of time. This type of seal cannot be repaired. Sources for replacement include Burt Morgan [former WRV employee] and a radiator company in Portland, Or; and perhaps others.
The CAC is the radiator structure in front of the coolant radiator which is leaking. The CAC cools the compressed air exiting the turbo before it is returned to the engine. These CACs may have changed over the years but the earlier ones have rubber gaskets on either end that can eventually leak--reducing turbo boost to your engine.

Problem Solved

Thanks to all for their input. Engineer Mike put me on the trail of a new, improved radiator from the former Sales Manager of Western RV in Washington. I have ordered a new one and it's on the way to me.

Can the information on the new improved radiator including the former Sales Manager of WRV be posted to the thread so others might benefit? I believe mine's starting to "weep".
