Coolant tank bleeder screw
 

Whyyyyy is it plastic??!!
I promise I wasn't twisting that hard.
The cap just sheared from the body. The threaded portion is still in there.:rolleyes:

They do that........dealers have them in stock and the old one will screw out easily. I use a small screw driver and gently tap it and move the broken plastic stud.

Check the tank for leaks, they all leak and end up having to be replaced, the tank is made out of the same defective plastic.

So are the timing chain guides in the V-8's.

Just replaced the tank. Replaced the coolant as well. Was trying to bleed the air and *snap*

You can buy brass bleeder and drain screws. Just don't over tighten those lol

Plastic screws are often used in plastic housings because overtightening will result in the screw snapping, and the housing (usually the expensive part) being recoverable. Metal screws in plastic housings result in stripped threads in the housing, and a perfectly fine screw (cheap part) but a stuffed housing.

Ditto what others said above...it shouldn't be too hard to remove the remaining thread shaft that's still in there.

You can drill several shallow holes to make an emergency slot (in the broken piece) that you can stick a screw driver into to back it out. Or you can drill a small hole then super glue a throw-a-way screw in...then back it out once the glue dries. Or you can heat up the end of a metal screw driver (make sure that the handle doesn't get hot)...then press it into the shaft that's still stuck in the tank...then once cool enough, insert a screw driver and back it out.

Good luck, and remember...it doesn't take much to screw in the "plastic" bleeder screw. Plus there's a little rubber gasket that is there to prevent "spillage/seepage" as well. :)

Heat up a screwdriver and jam it in there and turn

Thanks so much for these tips. :thumbup::thumbup:
