Hoping you guys could quickly assist me. We've changed multiple hoses, expansion tank - and a couple of days ago we were driving and received a engine overheating light on the dash. To pull in over I popped off the engine cover and noticed the coolant was spraying from this little 2 or 3 inch part. Looking to replace it, but I can't find it on any diagrams. Would anybody happen to know the part name / number and the tube that connects to it. Thank you
