Water Pump to Heatercore Hose (T1N)
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 all T1N Sprinters, years 2001-2006, OM611, engines OM612, and OM647.
