I will need to change oil soon and this will be my first time doing an HHR. I'm use to doing the typical spin-on filters and the cartridge type on my '66 Chevy. The HHR filter looks easy especially doing it from the top.
Is a gasket used on the drain plug? If do what is size or part number for it?

Thanks.

 

Oil pan plug has an o-Ring . No need to replace it.

 

Funny. I've had this new HHR drain plug sitting in my computer room for 3 years. Bought it at the dealer because my original on the car was leaking. Wanted just the rubber gasket but the plug AND gasket where only 6 cents more than the gasket alone ! Weird GM pricing.
The gasket is not an O-ring. More of a flat washer with a ridge seal. It sits in the recess of the drain plug.

 

I love my Fumoto valve

"Shorty" socket is very helpful to remove oil filter cap, any auto parts stores usually have them.


Oil Filter will look like this, Oil up the O-ring & others, so it doesn't scrape up the O-Rings.

 

I stand corrected, the plug has a washer not an o-ring .

 

Oil pan plugs are essentially standard on many GM vehicles. As such, and I have all GM vehicles, I purchased 12 washers in a plastic bag for $1.00.

 

Like these at RockAuto?

 

I've never replaced my Oil pan plug washer. Still the OE one.

 

Me too, but they are available. For future readers.
