Hi, our gs300 has started to show hot on the inerior temp guage and when the bonnet is up is clear to see that the water in the expansion bottle is burbling away.
It also seems to take a while for the air through the blower to get hot though??
The fan infront of the radiator comes on initially at startup, is this correct??
I am wondering if it could be the thermostat or temp switch??
Any ideas??
Thanks.
