RE: Coolent Mystery

The sensor in the coolant bottle. The only reason the light would come on is if you have low coolant or you are overheating and you say you have neither

RE: Coolent Mystery

Isn't the coolant temp sensor notorious for malfunctioning in these cars?

EDIT: Wait wait... the TEMP sensor IS indeed notorious for malfunctioning... but the coolant level sensor is known to kick the bucket as well, no?

RE: Coolent Mystery

What color is your temp sensor. If its green its the updated version but that still doesnt mean that its good. Usually the temp sensor kicks a check light too. I am still betting on the level sensor
