Good evening. New member here, reaching out in frustration. We have have a 2004 Discovery 2 and a few months back it began overheating and sending coolant out through the overflow tube. We replaced the thermostat and the head gasket. Everything ran perfect for exactly a month and half. Last night the vehicle overheated again and literally spewed all of the coolant out through the overflow tube. Any help would be appreciated.

 

pressurize the coolant system and see
I hope you don’t have a cracked block. I had a 2004 and block cracked. Can’t believe the aftermarket warranty covered a new block from Atlantic British

 

Thank you. We will look into that.

 

Which cylinder cracked on your block? Any idea why?
