Hello, not sure if I am doing this right. I joined because I have a 2006 HHR that has an oil leak from the main oil line. I think that is one of the lines to the oil cooler, I also have to replace my thermostat. Thanks for all the info that is available. I think I can do the the thermostat myself, not so sure about the oil cooler seals, if that's where the leak actually is coming from.

 

Welcome to the site, use the search window to type in what info you need there are many threads on both subjects, both have been tackled in a driveway or garage.
It all depends on your tools and comfort level with your wrenching skills.
The oil cooler o rings I have changed on a friends 06 not a fun job but not a bad job due to limited space .
