Massive heat build up in engine bay
I seem to be having a problem with massive heat build up in the engine bay.
If, say, im on the motorway or a dual caridge way, the temp gauge will go from half way to over three quaters quite quickly but the second i come to a stop the temp goes right back down to half way!
Now ive had some problems with my rad recently which burst and has radweld in it at the mo and a few months before that the head tank cap wouldnt hold any pressure so replaced the cap.
Air lock maybe?
