Happy Memorial weekend everyone, especially to those Sonic owners who served their country! This will be a quick post, not one of my long winded ones, I will try anyway! OK, I just had my oil cooler replaced at my local auto garage yesterday, and I asked them to use a G.M part for my 2012 Sonic with the 1.8 engine. My question is, a crack was found in the original oil cooler and the coolant was flushed and replaced along with an oil change ( I do that myself ) but let them do it since the oil may have had some contamination with coolant. How long have you found the new oil cooler to last after replacing it, it was pricey if your not doing this yourself and don't want to have to go through this again with this car. I do about 5,000 miles a year since I work very close to my home, and while I really like my Sonic, I will only put so much money into this car being its a 2012. It has 94,000 very well cared for miles.

Thanks folks

A question: After being on these great Chevy Sonic groups and reading about the Sonic's famous coolant issue's, the 2nd issue that most owners seem to come across would be the oil coolers going out.

I think at 94,000 miles, my own 1.8 engine Sonic might be starting to show signs of oil cooler failure.

My question is: Why does the Sonic's oil cooler go out even at fairly low miles, while other cars never ever have any issues with oil coolers? Is it the fact that our cars run so hot, is it the quality of the oil cooler itself, or is it just plain bad luck?

Thanks and I look forward to reading your comments folks.
