Does anyone have some info on how much is normal reading for engine coolant temperature via OBD on VQ30 engine?
My country ambient temperature is around 38 Celsius at daytime.
During high speed cruising at 130km/h the ECT is around 93 Celsius, but when climbing a long hill it can reach to 105 Celsius.
Even though the reading is over 100 but the temperature gauge still around middle line...

Hope someone can share some info about it.

Thank you very much
