JP Group Heater Core Return Hose — VW Vanagon Water-Cooled 1983–1991 (JP-9710-0)
Short answer: JP Group JP-9710-0 is a molded coolant hose in the heater circuit of the water-cooled VW Vanagon, carrying coolant back from the heater core (matrix) toward the coolant pipe. It replaces VW OE 251 265 054 A (JP Group ref 1114323100). EMPI lists it for 1985–1991 1.9 and 2.1 Wasserboxer vans; European sources list it from 1983 on. Sold each.

Why It Matters
Vanagon heater hoses run under the front of the van to the heater box behind the dash, where they get hot, cold and soaked in road spray. Old hoses go soft or crack at the bends and clamp points. A leaking heater hose means a sweet coolant smell in the cab, fogged windows, damp carpet under the front seats, and a slow coolant loss that can lead to an overheated Wasserboxer — and a head gasket. If you are bleeding air out of the system again and again, or replacing the heater core or valve, fit fresh hoses at the same time.
Installation Notes
- Let the engine cool fully. Drain coolant from the system low point before removing the hose.
- Compare the new hose shape with the old one before installing; the Vanagon heater circuit uses several similar-looking hoses.
- Clean the pipe ends of scale and old rubber, and use new clamps.
- Refill with the correct coolant and bleed the system carefully at the bleeder on the radiator and the heater circuit, with the heater on full.
- Run the engine to temperature and check every joint for leaks.
Frequently Asked Questions
Does it fit my 1987 Vanagon Westfalia?
Yes, if it has the 2.1 Wasserboxer. EMPI lists 1985–1991 1.9 and 2.1 vans.
Does it fit my 1981 air-cooled Vanagon?
No. Air-cooled vans have no coolant heater circuit.
Is this the same as OE 251 265 054 A?
Yes. JP Group cross-references JP-9710-0 to VW 251 265 054 A.
Which hose is it exactly?
It is the return hose at the heater core. EMPI also describes it as running from the connecting pipe. Match the shape to your old hose before installing.
What else do I need?
New hose clamps and coolant. Many owners replace the feed hose and heater valve at the same time.
Is it new?
Yes, new JP Group.
