[AT] OT drain plug size

[szabelski at wildblue.net]

I’ve welded a nut unto a drain plug before, and it worked fine. As far as the rubber gasket, you can pop it out before welding, it’s just an o-ring pressed into the bolt head. At one time I used to buy an oil filter for one of our vehicles and it came with a new o-ring for the filter cap and a new o-ring for the plug. At the moment I don’t remember which vehicle it was, too many to recall. 

You can apply a small amount of RTV to the drain plug, it will act as a lubricant for the o-ring and help seal if the plug’s o-ring is worn or starts to leak. I’ve done that on oil pans were the threads in the pan were worn and the drain plug would feel extra loose when threading it in. Use the black RTV made for engine gasket sealing, it dries fast and you don’t have to wait a day before you put the oil in.

Those look nice, and might work good with a slide hammer for pulling 
shims etc.  However if you look at the reviews there are a few that have 
broken the jaws by tightening.  My problem on this drain plug was the 
plug head was so soft the pliers just chewed the metal off.  The fine 
teeth of the knipex pliers worked the best.  I have a pair coming from 
Amazon for the next oil change. This was an ex Hertz car.  Perhaps in 
its history the oil pan could have been changed and a different plug was 
installed.  The oil pan could have been damaged on a parking block as it 
is the lowest point at the front of the vehicle.  Some really great 
engineering.  Just like the spare tire mounted underneath between the 
front seats.  You have to remove the center console interior and use the 
jack handle to lower the spare and hope has air in it.  We have had 
great service from the earlier models and that is the only reason I 
looked for another one when our old one was rear ended by a "texter".   
However, this is the last one.  I have had a problem every time I went 
to do any normal maintenance.  You have to remove the air filter box to 
get to the high side air conditioner access port.  It was one lb low of 
freon and I could not find the ports to hook my gauges to.  There is no 
dipstick for the transmission.  According to Chrysler, you drain the oil 
and measure it then pour it back in.  There is a you tube video of how 
to use the engine dipstick and mark it for transmission...   No more 
Dodges for me..
