1995 Chevy Cavalier mileage: 97,000. Last winter, heater with fan on never really got hot, only warm. A month ago, the temperature gauge started to show running hot, but not in red/danger, but close. I flushed system. Replaced coolant. Also replaced thermostat. Now, 1. Low coolant warming signal stays on, even though cooling system is full; 2. Engine runs on cool side barely above cold, and 3. Heater still does not blow hot air. Any ideas? Thanks

Test the low coolant sensor by removing the wire and check the warning light. Also, ground the wire and check the light. If okay, the sensor may be faulty. From what you describe, you may have the wrong thermostat. Your car should have a 195 degrees thermostat. This will also help the heater with hot air.
