WTF! Both gas tank strap bolt spins.....
- Thread starter moneypit
- Start date
Nut weld must have broken on the back side. Fixing is going to involve cutting the strap, and buying/fabricating a new one. Many folks see the condition of bolts like that before starting a job, and hit it with penetrating oil for a few days before trying to spin it out.
well I spoke to soon cause the front let loose too
funny how this was at the dealers just 2-3 yrs ago for a new tank too..?? I wonder if trying to drill thru the head like a rivet would work? and then in the end, what might be a suitable fix "without" having a nut rewelded or tacked up there since I have none.

Doesn't appear to be how mine looks, maybe since I got a 02' verses your 08'
It does appear that maybe the dealer installed tank is where this initially happened? and the tech installed bolt/washer & nut cause it don't look 13 yrs old.
Well I made progress, I was able to get the rear out by wedging a pry bar between corner of square upper washer/nut?? and miraclulously it came apart!
The front one doesnt afford me this plus it seems the washer is pulling thru the mount hole pita! I can't get a hacksaw or electric sabre saw up in there to cut the threads..figures

Good deal.moneypit said:Advance auto had replacements
I'd probably over engineer it and hit with grinder to clean it up and ad some new steel.

You still have a steel rod/tube below the tank, in addition to the straps, right? (if I recall......)]

Yes correct, I got my GM f-clip/nuts which are twice as beefy as aftermarket as I thought making the next time(if needed) tank removal alot easier. For anyone doing this in areas that are prone to corrosion..like here in NY, I would advise of making sure you can get these out before any other line disconnection so if you have to grind...everything is sealed. Oh and if grinding watch your wheel against the plastic gas tank which I happened to catch at first and almost ground thru!

Thanks, MoneyPit!
I had all the problems that you did replacing the gas tank straps. Tried JB Welding a nut (M10-1.5 threads) onto the little "shelf" where the bolt goes thru. Looked good, until some rust/scale fell into the nut and jammed it all up.
Hoo-ray for the G<M part--off to buy one!

Guess WHAAT? Yep--this Genuine GM part will work in my 2003 Silverado short bed 4.3L V6 4 w/d, BUT--there's absolutely NO ROOM to "slide" it onto that frame bracket where it should be with that bottom retaining clip.
No room at the inn "thang."
Had to cut off the bottom portion of the retaining clip (the height of the new nut was an issue) , "shave off a bit on the sides" via Mr. Grinding Wheel so the "modified" nut could easily slide in, and position it in that very narrow "slot" where the OEM nut was welded to the frame.
It works! Got 'er done.
Guys--I am in my mid 70s. I've had GM products since 1963 (first one, a '56 Chevy Bel Air Coupe @$50) but I tell you this: I've NEVER seen such damage and corrosion to undercarriage, brake and fuel lines, sheet metal, as I see now with "new" vehicles. Here in No Ohio, they use rock salt, calcium chloride, and brine from oil & gas well on winter roads--pure DEATH to the chintzy metal used on today's vehicles IMHO. I try and keep my vehicle for 20+ years--it may be impossible to do these days.

I think the earliest models we're prone to rust. My 02 Bravada was in bad shape. My 06 Envoy is not rusty at all. Maybe GM used better steel ha ha.

You're correct! They did. My research showed that the earlier Silverados (1999 give or take) used DEFECTIVE CHINESE STEEL TUBING.
WHAT! The Chinese trying to cheat...hard to believe (sarc)
When I called GM about my brake lines bursting, they said: "Oh, you're the Chevy years that we BANKRUPTED in court. You're out of luck. Can we interest you in a brand new Chevrolet?"
I had two words for the GM lady on the phone--and they were NOT "Happy Birthday!"

Are those the pics of the recovered Titanic?
Not to worry, Locksmith! Like the Motown song goes: "Your day will come..." unless, of course, you are South of the Mason-Dixon Line where NaCl and brine never show their ugly faces. Let me know how your rig is in 17 years!

Sorry I dont mean to revive a dead post but I mistakenly bought the Dormans showed in this post before I saw they didnt fit, ordered the nuts from the dealer and they are on the way but, did you try the bolts from the Dorman part in the dealer nuts? Just wondering if Ill need to go buy bolts now

So I got the nuts from the dealer, for future searchers, the bolts from the dorman kit DO fit the oem nuts from the dealer
