I have a 2001 Dodge Intrepid and my check engine light came on but dont coolant does that mean need to change coolant?

The check engine light can indicate various system malfunctions and does not specifically signal low coolant levels. You should retrieve diagnostic fault codes using an OBD (Onboard Diagnostics) scan tool or have it inspected by a mechanic to identify the underlying problem triggering the check engine light. The coolant level, however, should be regularly checked regardless and be maintained according to the recommended service intervals stated in your vehicle's owner's manual.
