So, I recently took my 2009 Aveo to a trusted mechanic because the engine light has been coming on intermittently. He told me there's nothing wrong that he can see, but that the problem might be originating from the thermostat.
We agreed to change out the thermostat, but then he balked -- because the one he bought didn't match the one in my car, he said.
I know almost nothing about these things, so I got him to show it to me -- here's a photo:
Can anybody tell me whether something's amiss here? Thanks in advance.
