My service engine light is on and I didn't pass my inpsection with fault code
P0128:cry: The SUV runs ok so I wasn't too worried. I took it to AutoZone and they said I needed anti-freeze, it was added, that didn't make the light go off. My temp guage reads ok. Any suggestions as to what might be the prob???
:thx

Welcome, but did you run a simple search on "P0128" before you posted? I think the software automatically pulls up similar threads before allowing you to hit Submit.

Anyway - it's been discussed EXTENSIVELY.

Autozone staff, as you found out, are not mechanics. Their advice is worth exactly what you paid for it. Was your radiator (not the overflow tank) low on coolant at all?

If not, and if it was you have to fix that problem first, then you'll discover P0128 is almost certainly a bad thermostat. Has your gauge been reading the usual rock solid 210, or lower than that?
