Hello, was wandering if anyone could shed some light.
I have a 2004 impreza wrx and in the past few days it has started to over heat when sat still. I've owned the car 2 years and this is the first time it's done it. However, I can get the temp gauge to drop by turning off all exterior lights and any heating? Seems odd. I've looked under the bonnet and can't seem to see a coolant redo lit I think the prev owner may have removed it, could this now be causing problems?
Sorry if this is a silly question
