Last night Julies TDi overheated. I hadn't realised but the rad sprang a leak and dumped the coolant, first I knew was the guage shot up to the red.
By the time I got off the motorway it had cooled down to normal, but there was a lot of water missing.
Now when I start it up water gushes from the rad or if I take the expansion tank cap off it looks like it's bubbling through the coolant.
The hole in the rad is BIG, it won't hold water now even stood still.
So, has the head gasket gone too now? could it just be the water pump forcing the coolant out or am I clutching at straws? do I put a rad on first and see?
