I have a 2000 Dodge Neon that overheats as soon as the car warms up. I have checked everything. The Thermastat, Water pump, Sensor, Fans. I have no clue as to what it could be. The car only has 80,000 miles on it. Anybody have any ideas? Thanks D.R. ---

These cars were noted for faulty head gaskets. If everything else checks out then I’d look at that. ---

Have you checked the radiator cap? A cap that is unable to hold pressure will cause the radiator to boil over when the car warms up. Ed B ---

How do I check the radiator cap. The boil over is at the overflow bottle.
