Yes,

1. Thermostat can be stuck open. After 60-70K miles, the Thermostat is no longer reliable.
Replacement is straightforward. The KEY thing here is a long Torx screwdriver:

I did it without draining the coolant (it was only one year old).
However, this procedure will cause a loss of roughly 1 liter of coolant anyway.

I bought my thermostat from here for approx. $15.00:

2. RE: Radiator Fan running.
Maybe the sensor is acting up.
This may be the source of battery drain as the fan consumes alot of current.

Look down below the thermostat area along the engine block.
Follow the ECT wire as far as you can see it.
Mice like to chew on volvo wire harnesses.
I have seen a few where the mice chewed on the ECT wire
and caused the fan to run all of the time.


Good Luck
