Oil drain Plug

[tnt31]

I recently purchased a 2008 Chevy Cobalt with the 2.2L.

Was peforming the first oil change since purchase and the oil drain plug did not seem in good shape.

I had a Dorman 090-91.1 that seemed like a match for the drain plug I removed with the exception the new Dorman is magnetic.

However when I look up the vehicle on Dorman's website it indicates the correct plug is a M090-175.1

Dorman list the 090-091.1 as 'Oil Drain Plug Magnetic, M12-1.75, 15mm head'.

Dorman list the 090-175.1 as 'Oil Drain Plug Pilot Point, M12-1.75, 13mm head'.

Looking at other specs the 090-091.1 is about 1.19 in shank vs 1.024 for the 090-175.1

Do you think OK to use the 090-091.1 drain plug in this application?

Since the thread size and length are the same....it should work. But to be on the safe side.... install the 090-91.1 and see if it leaks.

Too much work for me, I would just go to the dealer and get a drain plug.

The M12-1.75 part is the spec that matters. The size of the head only matters when you're picking which socket to use to remove the plug.

Of course the replacement plug on-hand is OK to go.

The possible differing feature would be a flange or shoulder on the drain plug to engage a gasket in a particular way.

Is there a gasket involved?

GM usually uses a rubber ring in a metal washer, they are good plugs.

Aren't they only a few bucks iirc? Hard to beat that deal. On the Accord the dealer automatically replaced it and added the charge to the bill. No biggie.

 

[Trav]

Yes they are cheap.

Thread diameter and pitch is really all the matters. Try it since you have it.
