Several months ago I removed the gas tank to weld up up a leak around the filler neck and to clean out 20 years of accumulated crud. However, for the life of me I can’t get the front bottom mounting nut started on the stud. It’s in an impossible to reach location with the intake manifold above and the exhaust manifold right next to the stud. There’s not enough room to get the nut started with a socket. I’ve got every imaginable swivel and swivel socket and crows foot but there’s not enough clearance from the exhaust manifold to get a socket on the nut. I hate to pull the intake or exhaust manifold just to start and tighten one nut especially since I removed the tank without doing that chore.

And yes, I absolutely do not recall how I got the tank unbolted and removed... The ravages of old age.

Any ideas?

Thanks, Craig in the Ozarks.

Should not have to but 12 point nuts may be the easiest answer. Pitstop.com. I put Allen head cap screws on my carburetor.

Start it with your fingers and use a wrench or pliers instead?

A child's hands usually can do things like that better than mine.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄

I have a friend that's standard answer is,"Go get a triple jointed Chinese kid from the assembly line."


I know it can be done,but always with great difficulty. If I remember 1/4 inch drive sockets help. As i get older and stiff joints who knows if I still can.

Are those 1/4 inch bolts? If and only if I am remembering the right parts,they should be. At this stage of the game have they rattled around loose and been taped out to a larger size? That would make it harder yet.

I actually used a little bit of all the suggestions ( started by hand, 1/4” drive with swivel, etc.) finally got the nuts on and tightened. No Chinese (or Peoria) assembly line worker but a willing pair of female hands helped to get the nut started on the stud. I guess at the factory they assembled the entire pony motor including the tank put it in place. Definitely NOT field work friendly...

There are a few annoying things like that on these machines. Definitely helps if designers have to "eat their own dog food"

We used to own a 2010 Chevy Malibu. In order to change a headlight bulb, the entire front clip had to be removed from the car. Not sure whether that was from the engineer not eating his dog food or GM trying to generate more work for its service departments. Just to be safe, I went to an independent mechanic's shop to change the bulbs out.

Things aren't really built to last these days, or be fixed. Only built to be replaced.

I have a 2005 chevy silvarado 1500. It has something like 35,000 miles on it. The speedometer stopped working, the stepper motor wasn't working right, so I replaced the stepper motor to get the speedometer working. A few months later, now the Tachometer doesn't work. I may need to replace the stepper motor in that.

Considering the few miles on the truck, it is a wonder why anything is really breaking down on it.

I'd take an awkwardly placed nut and bolt over having to replace a stupid little stepper motor every year just to have functioning dash meters.

I have the 04' and have had the cluster repaired twice. Just send it off and get every stepper and light bulb replaced, well worth it.
There are a few years GM production that are well known for bad cluster design. They should have all been replaced for free with unlimited mileage.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
