Hey Guys! If ANYONE could help me it would be great....
I have a 98 Dodge Neon. I recently had the engine replaced and the mechanic did a wack job. I now need to replace the majority of the engine mount bolts, and realign the center pully for my belt (located on left side). To be honest I can't take it back to the origional mechanic and have to replace the bolts myself. If anyone knows where to find the leanth and width of the bolts (the dealership and chiltons manual had no answers) it would be greatly apreciated. Also, if anyone has advise on realigning the center pully-it's eating up my belt-it would be really helpful. I'm stumped for resources. Thank you in advance!!!
I can help you by telling you that you need to learn how to go to the "Introduce yourself" forum, and introduce yourself, before you will get any help from anyone.
Ok, fair enough. But now that I've introduced myself would you help me now? :) Pretty please.... :oops:
Sure thing, but first I have to get something straightened out in my mind.
If somebody put this in their introduction;
Why would they need help with a simple task like that? I mean really, if you grew up under the hood of a car, installed your own turbo and swapped out a few other parts (whatever they may be), why can't you figure out something as simple the size of a few bolts or how to align a pulley? My guess is you didn't bother to read this, specifically the last sentence.
I think the answer is petty clear but I can't wait to hear your comments.
It may seem simple to you, but not to any of the three mechanics I've had look at it. First of all, I called the dealership for the bolts measurements.I'm missing 2 front mount bolts (m10x1.5.25) and 1 rear (m12x1.75x60). The front mount bolts simple don't fit. a 10.9 is too small-there's no 11-and a 12 is too big. Therefore the dealership aparently is wrong or left out some important detail. Second, the pullys are off the old engine. Maybe this is why I'm having trouble. It apears that the center (alternator) pully is out of alignment. However, there's only one place where it locks in. (I took the alternator off and looked) I can't imagine that the other two are out of elignment in exactly the same amount. The whole thing just doesn't make sense to me. I'm not pretending to sound like I know more than I do just to show off. I honestly ment what I said in my intro. However 3 mechanics, a dealership, and myself are all stumped. If this seems simple to you please lend us some assistance. It really would be greatly appreciated.
I'm intrigued about the 6" heels and mini-skirt... :screwy:
I'm intrigued if you know anything that could assist me. I'm sure you've seen plenty of girls in 6 in. heels and a mini skirt. Come on...a guy with as many post as you must know something to help a girl out. :)
Nope! As my title makes clear...I'm only here to cause trouble and edit
out pornography. It is so demoralizing to women!
I'm 0-2 on the automotive problem diagnostics. :doh:
vwhobo is the one...among two or three...to listen to for general wisdom and automotive queries.
So tell me, how does one get on his good side? I don't think he likes me
allready...LOL. As for the porn...a little porn never hurt anyone (Just
teasin') Thanks for the suggestions!
Do you ever get the feeling watching some one do something knowing that you
could do it much better and faster if only you had your hands on the
subject? I think that is what vwhobo is "frustrated" at. Many people on
the forums take offense at him too quickly and miss out on his help because
they are too easily offended at words that may sound offending, but truly
mean nothing other than wanting to kill the lazy syndrome in today's up and
coming "car enthusiast." You are doing just fine. Keep the questions
coming to him, know that he does have the answers or will direct you to
someone (a qualified mech.) who can better help you. He's quite honest and
forthright in what he knows and can help with vs. what he doesn't know and
can't help via these forums. :thumbs:
may i make a sugestion... maybe its a metric verses non metric problem?.. lots of metric bolts etc apear to fit but dont..(i speek from dumb experience!).. or a speciel thread form thing...BSF/Whitworth or terror of terrors fine metric and course metric... (yes they have them! usualy the fine is used on bigger bolts like motorcycle axels)

You asked for the lengths of the bolts and those are given in the numbers listed above. The 2 front bolts are, accoding to these numbers, 25 mm long and the rear bolt is 60mm long. That is about 1" and almost 2 1/2" respectively. The # after the M in the above numbers reffers to the bolt diameter (not the head) and the number after the first "X" reffers to the thread pitch.
I am not sure what you are reffering to with a 10.9, 11, and 12 but my recommendation to you is to stop fretting over this. It is a bolt, not some critical engine component. Measure up your holes and the length you need and find the largest bolt you can fit in the hole with just enough length so you have a few threads left over after you put the nut on.
As for the pully issue. If you have a missalignment issue, you may have to put in some spacers to get the pully lined up. Now I had an issue with what I thought was a misaligned pully that actually turned out to be a very pitted pully. The roughness of the pully was actually eating away at the belt. So make sure your pullies are nice and smooth and use some spacers to get that pully on line.
Hope all this helps out.
Thanks for the help guys! I'm going tonight to re-measure the sizes and
hit the hardware store for new bolts. As for the pully-I never thought
about a spacer (duh!) I know the pully is out of alignment because it's
VERY visably different. I'll let you guys know how it goes. Thanks again
for the help. It's REALLY apreciated!
Just one point. Why go to all that trouble and time ?
When stuck in this same situation i beat my feet down to the dealership and ordered the exact bolts for the vehicle. ( After looking at the screen myself).
Sure it cost me more, but there was no guess work and i was sure that the bolt going into the hole was the correct pitch and strength.
If buying bolts, not only do you have to know something about the bolts
nominal diameterm threads per inch and length but you also need to know
something about the strength or material grade.
a bolt specified as m12x1.75x60 is a metric bolt, 12 mm diameter, 1.75 mm thread pitch and 60 mm long.
Bolts are not just bolts in automotive or other machniery. Failure to use the right strength fastener and torque the fasterner to the right torque can cause expensive damage at best, get someone killed at worst.
Numbers such as 4.8 or 10.9 stamped on the head of a metric bolt is the strength grade of the bolt. This means the material in the 10.8 grade bolt has a higher yeild strength than the material used in a 4.8 bolt. If you use a metric grade 4.8 fastener or an unmarked bolt (found @ the local hardware store which is an SAE grade 1) in an application specifying a 10.8 bolt could result in a fastener failure. This is due to excessive bolt elongation in to the "plastic region" of the material's stress strain curve for the material during torquing or result in a subsequent failure due to overloading
If in doubt as to which grade fastener to use, take your old one to the dealer, an auto parts store or to a good industrial fastener outfit and let them help you match the right material properties as well as the dimensional properties.
Thank for all the great help guys! Hitchhiker....Good point about the
Dealership. They said they don't carry the bolts in stock. It would take
up too much inventory and suggested where they go and buy them. They're
the ones who gave me the wrong measurements :) Go figure. It kinda makes
you wonder what they do with your car when you leave it there.
As for everyone else..thanks for the suggestions! I'll be honest, I had no idea that engine mount bolts would be so complicated. LOL. This should have been a much easier job. After your suggestion, tbaxleyjr, I did make sure I got the right grade. And yes, that was extremely important! It ends up the dealership gave me the right leanth and width-but the wrong thread. Good news it it now runs (whew!) and I'm having a machanic take a look at the alternator pully. I think a spacer and new belt should fix the problem.
THANK YOU ALL SO MUCH FOR THE SUGGESTIONS-THEY ALL REALLY HELPED! You guys are the best!!!
I don't use the dealership service dept. much.
Most dealers are OK although pricey and attempt to do good work and make customers happy. There are, however, a few who are a little flakey @ best.
