Water Pump to Heatercore
Water Pump to Heatercore, Small Elbow.
This hose is located right next to the turbo, between the turbo and the engine block. It seems to get the most heat damage of any of the hoses and is often in need of replacement, even if all the other hoses look to be in good shape. Inspect this carefully or just replace it to be sure.
Works for 2002-2006 ONLY
