try not to mix coolants as it can cause damage due to corrosion. I was told by mechanics to use only OAT and not HOAT. Also, only 50/50 should be used. Make sure the brand you use is capadible. (NOT ALL COOLANTS ARE THE SAME)
can you add some details to the video pls. did your shock leak out? i do see the damage but why replace it? was the car flashing service suspension on and off ???
Why do you think is so damned important to have crazy loud exhaust? Is it to announce "hey everybody, look at me!!" ? That's what harley bikers do it for. Is it to annoy neighbors or the police? Time to grow up.
