Dropped right in fits like a champ. Very happy that Amazon had these available.

Fits good. Rubber hose to radiator cap is not long enough for a 2014 dodge avenger. Keep the old hose

Lo compré con cierto temor de que no quedara y la verdad es que es de calidad original y la instalación sin problema. Buen producto y vendedor
