I have been learning alot from this site about Gen3 and done small works following the guidance described in this site until the head gasket issue that recently fully developed with rapid coolant loose with insane amount of white smoke filling neighborhood. Just saying Hi. I had so much good memories with Gen3 and sticking with Prius. But this time I am getting a 2021 Prime. I hope it is a better than Gen3 and even more reliable...
Hello and welcome to the forum! Do you have any photos of your Prime? Feel free to share them with us. Fellow newbie here.
I'd like to know more about your gen3 demise since that's what I have. Did you ever clean out the egr cooler system? How many miles?
