> minutes later and the car started no problems, temp gauge went to 3
> o'clock cooling fan ran constantly, drove to volvo no problems
> whatsoever other than cooling fan running constantly, volvo said "ok
> maybe a faulty sensor" they fitted a new thermostat and a new sensor
> and sent me on my way all was well for a month then exact same thing
> happened light on cooling fan stayed on, so I bought a sensor myself
> and fitted it, it ran for 15 mins before wrecking the new sensor,
> checked all the wiring apart from a tiny nic in the wire at the
> connection all seemed ok, tested the voltage coming from ECU and it
> reads around 5 volts, Volvo now want to fit a new ECU although they
