Check engine light[2000 zx2] was diagnosed as a bad temp sensor at autozone, so i picked up one up. I assumed sensor was atop the thermostat housing, so i removed it and noticed it was different from the replacement [3/8 thread instead of 5/8"]. Then i noticed beneath the housing what i thought was the right sensor--it to was 3/8 also. Now i'm thinking these are coolant level sensors.....Anyway, where's the temp sensor located?

thanks
