Can someone tell me what that plastic elbow tube is called on the backside of my heater coil? VW Golf 2000.?
Heater core tube? If it is the bend itself then say e.g. heater core tube with 90 degree bend.
Plastic elbow, on the metal heater core itself? Probably there would be two of them. Water in and water out. On the plastic box the heater core goes in? Just the one on the box. That would be a cavity water drain to keep it dry in there and cut down on Mold/Mildew. Heater CORE in the USA. ASE Cert Auto Tech, since 1978, 2003 GLI
