Radiator Fill Neck Problem
 
I was trying to "bleed" my coolant, and found this

IT seems that this "tip" (it connects to a hose, that runs down the frame to allow coolant to expel to the ground) broke off...there is a corresponding hole in the neck of the fill tube.

ANyone ever see this?

Can I just solder this back in place?

Thanks
Phil

Shouldn't that go to an expansion tank? What's to keep the coolant from running out when it heats up and expands?

I epoxied mine back on. Pipe doesnt hold pressure. Soldering works too. Thoughly clean both parts either way.

the pressure cap until it reaches way over 220. If it doesn't the cap is bad.

But the hose to expansion tank is before the pressure cap. The picture looks like the hose that goes to expansion tank, unless that is below what's in picture.
curious what that is

It's the hose that is hooked to the nipple on the fill neck right under the Cap. When the cap relieves pressure, the coolant runs out that hose.

We know that you know how it works.

Look into the hole in the neck of the rad,where the cap goes.
Then remove the cap,and look into the hole,
Notice anything?

The cap seals below the hole where the overflow hose should be.

Yep That's right. I do know that.

But Phil said in 1st post that the hose ran down to the ground.

I had the same thing happen on my generator(should have bought Mike's) coolant tank.
Used JB Weld, make sure you don't push the tube into the neck should just be sitting flush so the cap goes back on.

Check where yours goes. The little hose under the fill cap in the little door above the engine hatch.
