Es una pena, a menos de 1 año de uso fallo la bomba y tuve que cambiarla, aun siendo que en USA ACDelco ofrece garantia por mas de 1 año aqui en mexico las "garantias" son una burla a pesar de comprarla aqui, me mandaron con el vendedor el cual para mi es ACDelco los contacto y me salieron que solo tiene 1 mes de garantia jaja es una burla. Atencion Amazon si vende productos con descuento porque son lotes defectuosos esta pesimo
