My Sonic was leaking coolant and smoking like crazy which meant it was the oil cooler dripping on the exhaust system. I'd already replaced the thermostat and the valve cover and I wasn't losing any oil. After getting a quote of $900 that wasn't in the budget, I watched several videos and hunted down parts. After considering non-OEM parts, I decided that the cost savings wasn't worth the risk of having to do the 5-6 hour job over - either missing critical gaskets, misfits, and/or leaking after a short time. So I spent $250 on all GM parts, the 3 pipes and the oil cooler itself. It was a bit of a challenge but everything fit and the leak has been fixed. The YouTube video that I found most useful was "How To Replace Oil Cooler Assembly [ Chevrolet Cruze/Sonic/Holden Barina 1.8L 1st Gen 2011-16 ]". It will save a ton of time to have an impact driver to deal with all the nuts and bolts. It took 5 hours for 2 of us, both experienced working on cars. These are all 4 parts: https://www.amazon.com/gp/product/B004JBE9XU, https://www.amazon.com/gp/product/B004JBJWKU, https://www.amazon.com/gp/product/B01E6CLQJQ, https://www.amazon.com/gp/product/B0792JGR8N.
