No good on warranty
Tony (Florida) | September 9th, 2019
I bought the cover for 2011 F250 found down the cover has a Hair crack . Contact the company and they told I have to send the cover and wait if they will warranty the part. I ask if they can send me another one by getting my card info and they said the only way will be me buying another and then they will reimburse me the money. Shipping has to be also pay by me . I don’t how other companies work but I have similar problem with mishimoto and they send me another radiator with no problem and they were in touch with me all the time. Mag hytech didn’t even ask for an email or pictures of the hair crack .
