VF V6 Coolant Temperature Sensor

Hey mate how did you go? What was the problem in the end.?
I'm having same issue where temp reading is 3/4 about 118c. When parked the fans are constantly on when idle and temp not going down.
When I rev the engine temp keeps dropping. Soon as I idle temp goes up again

In the end I replaced the radiator cap. This increased the cooling system pressure and didn’t have any further issues
