Hi Ya

Exactly the same as i had a couple of days ago.
Cold air out of fan,temp gauge right up,and hot air when foot down.

I checked my header tank and to my suprise it was empty,i filled up and all is working as it should now.
I was very concerned why and where the water had gone,On inspection i have found bottom of rad weeping.
I think that when the coolent is very low,you dont get any water through the heater matrix until you put foot down.
i hope this helps.
