Hi
My insignia started overheating this morning got up to 130°+. I noticed that I'm getting lots of back pressure and very little coming from the return pipe. After it had cooled down a little I released the header cap. The coolant shot out the over pressure pipe. To I left it to cool longer. When I finally released the header cap the coolant was way below minimum.
I topped it up and ran the engine, the coolant continued to rise from the bottom with nothing or very little from the return pipe!
What your thoughts head gasket? Water pump? Other?
Thanks
