I have installed the OBD II bluetooth adaptor and the torque application in my android phone... Now I can read the coolant temperature. What is the normal running temperature for Volvo S80 /V8/ 4.4 ?

There is no temperature gauge at all in the vehicle. I am trying to find out how to fix one on my own

Hi,

Can anybody suggest/ recommend how to buy and fix a Coolant Temperature Gauge ?
