Stripped pan bolt
got a stripped pan bolt on the auto trans and its just had a service done on it, so can you do a helicoil on it with out taking the pan of again or not.

hole in the pan will get in the way of fitting a helicoil is it one of the bolts that go into the alloy where you cant fit a nut on it or one of the side ones where the bolt comes right through
I tune the oldschool way fear on the passengers face and knuckle colour cant go wrong

Passenger side corner back one
A mate of mine stripped one of his trans pan bolts.He just left the stripped bolt out altogether,tightened the rest of the bolts up,and it didnt even look like leaking.And as far as I know,it never has.His was half way along one side though,a corner bolt might be a different story,it might not seal up properly.I guess you could try it to see if its gonna leak.The only other thing I can think of is buying another bolt thats the same length but is the next size up,and getting a tap and die set, and re tapping the hole out to the next bolt size.Also if you find the next size bolt is too big.You might find that if the original thread is imperial or metric, that there might be a slightly bigger thread size between the two units.Example,you can go from a metric size to a slightly larger imperial size,or vice versa.Some of them are only slightly different in size,so you might find its just enough to tap another new thread without taking the hole size out too far.

if its a bolt that bolts the pan up to the housing, your cheapest option if you dont have a tap and die set, is to buy a helicoil re-thread kit.
Plus, by drilling out the stripped thread and putting a helicoil insert in, not only does it return the hole back to the original thread size (same bolt, not a bigger one) but i believe the helicoil inserts make it a stronger fitting. I know for a fact, you can by the kits from blackwoods, coventry fasteners, thomas warburtons, and even some places like bursons, repco, etc.
Ring around, you will be surprised in the price variations. you just have to know what thread size, AND pitch the original bolt is.
no worries thanks for all the information ill go helicoil way to make it stronger, dont ya just hate the alloy shittho rather have steel anyday lol.

I did a search and found this about the helicoil and would like to know if it will be ok for one of the bolts on the thermostat housing on the VS.
I got new bolts and one is just tight.
I let the sealer dry over night and will fill it up this morning and hope it doesn`t leak.
All feed back seems to be good about helicoil.

Real cars are steel cars.
No problems with a helicoil on cooling system parts.
As well as loctiting the coil inplace, I would also use some coppper grease (such as Wurth CU800 or Penrite Copper EZE) on the bolt threads to prevent them from unscrewing the helicoil.
If you wanted to go one better than a helicoil, use a 'timesert' instead. Works on the same principal as a helicoil but is a cylinder with a thread in the inside and outside rather than a coil.

Problem with using a helicoil is the cost - around $30 for probably the one and only time you will ever use it.
As mentioned above, not replacing it probably will not cause a problem, and even if it did leak it would only be a weep. If it was me, I'd get a short metal thread self tapper the same length as the old bolt and a fraction thicker and gently screw that in - no way can that cause any damage.

I wouldnt locktite it in, it comes thru and cloggs up the inside thread and sticks the bolt in with it.
Turning the helicoil backwards before you break off the tang is normally enough to lock it in place. I have never had one come out on me

Hence the copper grease.

Yeah but you still have loctite in the threads of your helicoil, so its still likely to come out when the bolt is removed.
