Ok, I finally got a chance to drive it up to temp again then park it on the ramps and crawl under to try and get alook at the dripping, without getting hot Dex in my eyes. The dripping is coming from the back of the engine, slightly off center toward the drivers side. So I am guessing behind the thermostat housing.
I snapped a few pics, but it's mainly of a wet axle, lol.

Thermostat housing and or transfer pipe oring.

Yeah, I don't think I have the skills and tools to tackle that. Looks like I will be taking it to the mechanic.

It’s actually pretty easy, I have done it from above after removing the air cleaner box . You need to drain the coolant, then remove the coolant temperature sensor, a 19mm deep socket, then 4 10mm head bolts . Change the oring and reinstall. Took about an hour .

Thanks for the added detail. I did some more searching with that info. If it is this repair, that sounds too much for me. https://www.chevyhhr.net/forums/main...-repair-61008/

I also found this video, and doing it all by feel while blind would probably be too much for me.

Okay, no harm in that. At least you know what is involved and the shop shouldn’t charge you too much.

I realized that I never provided closure. The shop replaced the o-rings, refilled the radiator, changed the oil, and replaced a valve stem on a tire that had a slow leak. Took a couple of days because they are understaffed, but it was all fixed by the following Monday afternoon.
Thanks again for the diagnosis help.

The O-rings for the oil cooler or for the coolant tube from the water pump to the thermostat housing?

Timewalker

the transfer pipe from water pump to thermostat that OldBlue diagnosed.

It’s an 08 2.2 , so no oil cooler
