I don't want to change my radiator because the overflow plastic nipple broke. Does anyone have a good permanent fix? I thought about drilling it out enough to fit a small piece of copper tube down the middle of the nipple and cement it all together. What type of glue works best on this type of plastic? Thanks.

 

None is releiable forever. The tank plastic gets brittle. Some have drilled out, threaded, and glued in a threaded nylon hose b*a*r*b. JB Weld. You may prefer to have a $150 ish replacment radiator than a patched one that may crack elsewhere.

 

This is the one I think I'll get if I have to. Land Range Rover Discovery OEM Radiator

It's not $150.

 

Others have posted about radiators at about half that. Of course, quality is always an issue. Here's pix of what is inside that plastic tank, not a lot of meat to work with.

Dave, you get what you pay for in this world, I recently installed that same radiator in my Disco, yes, it is more expensive and the only one that is not a American made knock off or worse yet from China. It is stamped right on the box, it is made in Scotland.
Don't forget to replace your t/stat with a new 180 degree soft spring if you have not already done so.

 

Forgive my responding to a very old post, but this just happened to me, while trying to fix a squeaky fan belt on my 2000 DII. The thought occurred to me that if the radiator is now trash, what do I have to lose trying to fix it. There are any number of hacks that will solve this problem. Here is the hack that worked for me:

I took a 1/4" carriage bolt out of the junk draw and center drilled a 3/32 hole, 1.5" through the middle if it. I used a small lathe, but you could use a drill press or even a hand drill, if you first make a suitable center guide. I then trimmed back the broken plastic stub sticking out of the radiator, using a razor knife, and drilled a 7/32 hole through the middle of it. (I spun the drill bit by hand, to avoid launching it through the front of the radiator if it bit the plastic too hard...)

The 1/4" bolt threaded quite nicely into the new 7/32 hole in the radiator. I removed the bolt, cut it off at 1.5" and re-threaded it back into the radiator. The hose fit loosely over the threads and was secured with a clamp. DONE!

At some point, I'll probably need to replace the radiator, but it won't be today, and it won't be because of this ridiculously flimsy plastic connector.
