I'm talking about the screws that hold the black plastic piece to the metal filler neck. I removed the one screw, the one closer to the engine. Then I tried to get the other one out, and I screwed the top of the bolt right off the bolt. So the threads are just sitting in the housing there.

-Do I need to get a new filler neck?
-Can I drill and tap a bigger hole?
-Can I just use a C-Clamp to hold that side down so no coolant sprays everywhere?

 

hmm the first two options make snece to me, dont try the c clamp that wont work worth a darn!!!

depends a tap and die set are somewhat costly, if you can find a filler neck in a junk yard for 5 dollars id try that......

depends on how easy it is to find another filler neck tho!

 

try soaking it in a penetrant for a few days. then drill a small hole in the center, and pound an easy out into it. then, if you have access to an impact wrench, impacy it out. i would really try to get an impact though, you need all the tapping. if you can't get one, put pressure on the bolt, and tap it w/a hammer. let me know how it goes...

 

Last resort is you might get away with drilling it all the way out and retapping it a size larger.

 

Yea, RX-7 Parts are scarce in these parts, especially junk yard cars.
What kind of penetrant are we talking about here? Like WD-40? or something extra special.

 

These things are not that rare, and I'm sure if you posted a WANTED ad in the classifieds section in here, you'll get several offers.

Penetrant = WD-40, Liquid Wrench, P'Blaster, etc.
They all work okay, and some will argue one is better than the other.

If you got a good pair of Vice Grips, you might be able to back them out after getting them soaked.

get easy outs, it will work perfect

 

i have a filler neck i can hook u up with pm me if u want it...

 

New Chapter in this saga...
So i tried using easy outs to get the bolt out, all it did was make a nice bowl shape in the bolt. So I decided to take of the filler neck and bring it into school so I could drill and tap or do what ever it takes.
Filler neck bolt 1, out. Filler neck bolt 2, halfway out, then snap. I am soooooo pissed. Now i get to stare at my thermomstat and half a bolt sticking out. I don't have heat/electricity/lights in my garage cause it's an apartment garage. I can't take my car anywhere without coolant.

What am I supposed to do? I can't "soak" this thing. Do I take a propane torch to it? Even so, i can't get a good grip on it with a vice grip.

 

lol ohh boi........... ok well now your gonna have to take the water pump and water pump housing off..... lol

 

Is that absolutely nessesary? I'm afraid to touch anything else that has had coolant run through it. I'm gonna bust every effin bolt on this damn car.

 

well spray penitrant on the half a stud thats sticking out... then try to screw it out of the hole with some vise grips or somthing or using two nuts locked together to try and back it out....... if u cant get it out with it on the car, then your gonna have to do somthing....
