Oil drain plug torque

I'm coming up on *my* first Challenger oil change here before the snow flies soon in MN ...........


I done searches here and elsewhere, and I seem to be finding different answers for what
torque to use on the oil drain plug on my 2010 RTC 5.7L.

I've seen 20 ft lbs and 25 ft lbs.

Can someone post an image of the service manual showing the correct amount of torque to use ?

Or point me to an online reference ?

Thanks.

Make it tight but don't go crazy with it.... In all my years around mechanics and dealerships I've never seen anyone use a torque wrench on a drain plug... just common sense.

Agreed. I have been an automotive tech for 15 years and I have never once used a torque wrench on an oil drain bolt. But some people like doing stuff to the exact specs from time to time. Even when it doesnt matter.

You don't need a lot of torque:

*oil pan is cast aluminum

*the drain plug has an very nice integral nitrile gasket and will seal readily.

PS: I've changed oil on both my friend's 300 and Challenger - the dealer's tech went nuts - it took both hands on a breaker bar to break the bolt loose...the oil filter on one of the cars - two hands and lots of force - thankfully the cap wrench held!

You want it tight, but not so tight to hurt her. You're over thinking this.

Your right...but EVERYTHING has a torque value if you want to get technical, and the OP is.

Which manual is that ? Can you post/email a picture of the page in the manual ?

My 400+ page owners manual says nothing.

I found a Chiltons manual that listed the following values:

Challenger 6.1L 20 ft lbs
Charger 5.7L 20 ft lbs
Challenger 5.7 25 ft lbs ...... sure seems like a misprint to me.

Here is what I have found in my 20+ years of rebuilding automotive transmissions...fasteners have torque specs for a few reasons, one of them being so the threads aren't over stressed which leads to thread ripping not to mention head rounding...go ahead and torque it

Sometimes you have to go the extra mile yourself because the dealer won't
