Re: Alfa 156 2.5 V6 overheating
It will definately not be the thermostat, if it gets up to 90'C whilst moving then it's confirmed.
One fan should always be running, so as DC says the resistor has probably failed there.
The water pump is the answer to the overheating though, the water is not geting moved aruond and this will cause overheating. I'm affraid that is not what you wanted to hear but it is the answer. Hope your due a cambelt too as this would lessen the costs.
