Yes, a clogged radiator can definitely cause overheating. Especially at higher speed driving, like expressway driving. Personally I'd replace it since everything else is new. A flush with a chemical cleaner may unclog the radiator but it will probably start leaking. Try Ebay for an inexpensive new radiator. I found one for my 2000 Grand Prix for $80 free shipping two years ago and it's been fine. Hope that helps! Jim

Take the radiator cap off and drive a new vehicle under it. A 2004 Neon is known for cooling and head gasket issues.
