Spark Plug & Oil Drain Plug Torque Specs

Guys,

Been searching and can't find the oil drain plug torque specs for my 04 Rubicon.

I didn't get a manual with my TJ and it's due an oil change.

Also got a new set of plugs to go in. Is there a torque spec for the plugs?

Anyone have the specs handy?

Spark plugs are 22ftlb and the coil rail screws are 21ftlbs. I seem to recall reading somewhere that the oil drain plug is 27 ftlbs.

Personally, I have never "torqued to spec" any of these. I just use common sense.

Just a traveling cat in a tall black hat riding a goat. Nothing to see here.

You will get use to not using a torque wrench for a plug change.

Stick with nothing larger than a 3/8" drive ratchet wrench and you won't have to worry about over-tightening them. With a 3/8" drive, I tighten them both to no more than one grunt. Using a 1/2" drive is just asking to overtighten/strip those sizes of parts out.

Getting Savvy...

When you have a choice, buy American.

Thanks. I guess I should have clarified that I have a history of stripping threads. I thought I would start out right on the Jeep and use a torque wrench from the start. Plus, good excuse to buy a better torque wrench.

That's a smart move. It's hard to go wrong doing things the right way.
