am going to remove standard fan soon and replace with electric.

Question: Does anyone know the best water temperture the car should be running?

ie: so i can set electric fan sensor to try and hold the right temperture, and if needed change thermostat to 62c instead of 76.5c, looked at service manual but doesn't say what running temp should be.

If standard stat opens at 76.5c running temp would be 76.5 or just over?

Any advice much appreciated

between 80 and 90 Celcius.

 

Anything below or above that and the ECU will start to make (small) adjustments to either timing , AFR and base-idle...probably meant to help to get the engine to the 80-90 Celcius operating temperature.

My sensor kit operates at 85 mate,
