JB Weld makes a plastic 'bonder' that might get you through until you can replace the tank. I'd do something like that and once it's cured and you can see that it's not leaking then put some super strong tape over the bond. Some thing like this

or even Eternabond if you happen to have some lying about. Anything to work as a back up to the primary fix.

It's called a surge tank IF you have a Freightliner chassis. They run around $125, takes a shop around 3 hours to replace it if you give them guidance. They do age out and weep but usually don't leak, which gives time to get around to doing the job at your leisure. (But...I did read about people who had to be towed when it leaked big time). I used Eternabond tape (found in the paint department of Home Depot) to seal mine up so I could drive another 3600 miles or so. And when it was time to replace, I did the job myself...Surge Tank replacement

Tanks are different for the Cat and Cumins.

I replaced mine for a Cumins 8.3 ISC with a metal tank from Freightliner, Not a hard job just ordinary tools and an hour or so.

When I first found the plastic tank weeping, I syphoned the tank dry, sanded the area and applied JB Weld. It held from RGV TX to Albuquerque. That was the closest in stock tank I could find. April 2016 $239.19

There been a number of listings about the tank pain in the neck to get in and out when you replace it use what they call t bolts. You can get home by releasing the pressure on a radiator cap it will stop leaking.

I had an '05 with the same problem. I bought a new tank from Freightliner. Not cheap. If you can get the tank off without destroying it, because it may be a bit fragile, you can dry it and wrap it with Gorilla Tape. I think it is water proof. Fill the tank with distilled water when you reinstall it. It might be a good time to replace your antifreeze if it is over 5 years old. See if you can find a replacement tank at a truck bone yard. I had to do some mounting mods to get the new tank to mount.

Go up a couple of posts. I solved the problem at a cost of about $110. For new. I would never go through that much labor to put in a used one. I will paint most of the front of this one and a drop material also to shade it.

Ken,
You found those tanks, like the one in the picture, for ONLY $98????? If they're the same as the picture, that's a STEAL! I replaced mine 7 years ago at a cost of $134.00 NOT including tax. I'd almost buy another one and hide it for safe keeping at that price.
