Good progress Michell. That coolant hose is not correct. The tap that it was connected to at the back of the engine is only a drain tap for when you need to drain the coolant out of the block. I’m not sure where that pipe should go to, but definitely not to the tap. That could be causing the vacuum you are seeing on the radiator hose. 😉👍
Yes I have delite it now and order New drainplog for that one now . You are so reighte Thats its not good and not orginal at all . I Will bring it back to original now Gordon 😊🚜
