Because I like to see where things are at and being a do it yourselfer for maintenance. I had to find out where the oil filter is.
I have the 1.3L engine. I can only assume the 1.2L is in a similar position. Under the car there is a plastic shield that looks like it covers a good portion of the undercarriage. There is a small cover that needs to be removed. I took these pics a few weeks back and do not remember the size of the screw. once the screw is removed you can remove the access cover and I am glad to see it has a spin on filter(blue)
My Equinox w/ 2.4L had a cartridge filter and required a special low head socket to spin off the cover so you could pull the cartridge out.
I did not get picture of the shielding as I did this with it still on the ground.

Awesome, I also like the spin ons vs the canister style. I wish my 18 ZR2 had the spin on, but it doesn't. I also have the 1.3 in my Trailblazer. Thanks for sharing!

Looks like the 1.3T uses an AC Delco 5549105 (PF66). I tried to cross reference that to an K&N Gold oil filter which is about the best you can buy, but no luck as usual, lol.

Funny to see the PF 66 is used in several GM vehicles including the Blazer’s and Silverado’s..So maybe these TB’s are built like a rock❤🇺🇲

We have a plastic oil pan which is where the plug is located.

do you have to take the whole bottom cover off to get to it

I believe so to get to the plug, but I haven't done it yet, so I can't say for sure. I'll have an answer in 2 weeks when I do my first oil change at 3k miles. No way I'm waiting til 7500k as the manual specifies. That's just too long for the break in oil. 7500k between changes is fine after the first oil change especially with full synthetic.

You can see the drain plug in the plastic oil pan in the lower right corner in this pic from the 2021 Trailblazer Group on FB.

ZR2LIFE,
Thank you for posting this pic. I have a pic of that, but was not sure when I was taking pics if this was truly the drain plug. Not sure how it works. Interesting to see with shielding off. When I do mine soon, I will take this off to be a cleaner, easier change.
Curious to know what the hose is.
