reach337 Posted March 21, 2021 Share Posted March 21, 2021 Has Ford fixed the problem in the 2021 5.0? We had a 2017 GT Premium that with the hood open, you couldn't hear it running. We traded the 2017 for a 2019 GT Premium. At 9400 miles, the tick, more like a rattle, became extremely noticeable. Its embarrassing to drive. Maintaining speed, it sounds like a diesel. It now has 12,400 miles. Wanting to get rid of it for a 2021. If the issue hasn't been addressed, and this awful noise is "a characteristic of the engine", then a brand change is in order. Not looking for smartass answers, if you know for sure its been addressed, your input is appreciated. If you dont know, please dont comment.

blksn8k2 Posted March 23, 2021 Share Posted March 23, 2021 My understanding is that the 2021 Mustang GT will continue with the same gen 3 Coyote as the 2018 through 2020. I have a 2018 F-150 and my Coyote has the same noise issues as your 2019 GT. The 5.0L Coyote in the 2021 F-150 does get some major changes with the addition of cylinder deactivation and a new belt driven oil pump design but I doubt either of those changes will result in a quieter Coyote. Neither of those changes apply to the 2021 Mustang. Quote Link to comment Share on other sites More sharing options...
GT69 Posted March 13, 2022 Share Posted March 13, 2022 The only thing they changed is that starting with MY21 they now recommend 5W30 instead of 5W20 oil. At least that's what I found out from my research. Quote Link to comment Share on other sites More sharing options...
coupe3w Posted February 4, 2023 Share Posted February 4, 2023 It would be nice if Ford would at least tell us where the noise is coming from or what is causing it. Is that to much to ask? Quote Link to comment Share on other sites More sharing options...
