Hi, just wondering if anyone knows either the name or part number for this small pipe with the foiled cover around it. It's developed a leak and caused a breakdown today after driving about 50 miles. Its dripping coolant every second, and nearly all coolant was lost. Its on a meriva b 1.4l 2011 petrol model. The pipe looks as though it's got a nut on one end and a sprung clip on the other end. Thanks in advance.
