I have a 2004 dodge 1500 quad cab 4.7 liter.

Asked by Sep 21, 2016 at 02:51 AM about the 2004 Dodge Ram 1500 Laramie Quad Cab LB

Question type: Maintenance & Repair

Why does dodge use a oil pan drain nut that
is not metric nor standard size . The nut was
not 1/2 inch nor was 13mm not 14mm. Nor
was it 9/16. Why would any car manufacture
make a bolt that needs to be changed
frequently. A size that nobody would have in
their tool box? Now I have a stripped nut and
cant change my oil. Might as well take this
truck to the wrenckers since its usr a matter
of time the oil in the truck burns up and
destoys the engine. Why can they not use a
size somebody would have in a standard
ratchet set?

Odd my 4.7 was 13MM. On Oil plugs that were rounded off I used a monkey wrench, got them off every time and then was able to replace it.

Yea I agree. 14mm is 9/16 just for thought. Like tennisshoes said use a monkey wrench or a pipe wrench and buy a new one and a socket for it. I am sure it is a normal size I have not heard it was something other, any size it could be would fail in standard or metric sizes. It may have been damaged a little, with these I just remove the wrench and use the socket that is correct and my hammer to lightly tap it on the head in the correct position that would line up when its on there of course.

This one wasnt 13 was to small 14 stripped it. My channel locked chewer up the nut so bad. Looks like I have to replace entire oil pan everytime i need an oil change. Its stupid


Look if you can not get on with a pipe wrench then drill a hole in it but not all the way threw it and buy a thread out bolt removal kit that catches on the inside of the drilled hole when in reverse, wait until you get the kit some you do not drill a hole first it drills the hole for you or you can also drill the hole as above and use a reverse thread die to thread the hole in reverse and put in a reverse threaded bolt in and back it out or weld a new piece of metal to it and back it out does not have to be a nut but could be or any metal that is easy to weld and grab a hold too, Put it this way I can get it out guaranteed without removing the tank but it might be easier for you to get it out if you remove the tank.

And when drilling a hole in a bolt do not use a bit that is the same size as the thread as you will destroy the threads on the pan. must be a size smaller or a few sizes smaller depending on you ability to keep it a straight hole. If you can get on the bolt still a little use a small torch to heat it up and then back it out. (not a cutting torch) Map Gas.
