So a little bit after the time I replaced my turbo amongst other things injectors, fuel pump and misc bolt on's I noticed that while my car idles it crosses that optimum temp threshold. I did lose some coolant when I replaced the turbo just never thought to top it off because it seemed little at the time. I also did notice that it's only when idle and has happened only a handful of times over a few months… As soon as I drive though it drops back to normal.
I'm thinking I need to burp the system as some enthusiasts point, out maybe a coolant flush would help?
Has anyone ran into a similar issue or know who has so I can begin my process of finding out whats wrong in the write direction?
