  1. Hybrid
    I have a 2014 q50 hybrid, I had a misfire in cyl 5 and upon inspection there was coolant most of the way up the coil pack well or whatever it’s called where the coil pack goes and connects to the spark plug.

    I have a RWD 2017 infinti q50 3.0t premium with just a jb4. I’ve been losing coolant and having my engine temperature go up for some time now. I’ve taken it in several times and passed the pressure test and internal leak test for coolant (so hopefully not a head gasket). This has me stumped...

Long story short I ended up having to take apart a coolant line which spilled coolant and required me to bleed the system(I guess). I have a vacuum lift kit but I don't know if I...

    So I noticed my multi way control valve is leaking on my 17 q50RS. As shown in pic below. After doing research I am seeing this part in only few places. Can I just take the top of & reseal it myself? Or the only way to fix this is to replace the part?

    Hello everybody, My Q50 is nearing 60k (currently at 53k miles). I am planning on keeping this car till the wheels fall off so I want to be meticulous with maintenance. I currently change the oil at 5k intervals. Therefore I have a few questions: Should I do a transmission flush or a...
