BPS Heater Core Return Fitting (2011-2020 Mustang)
Racing Use Only, Not Legal for Road Use
Part of converting a Coyote coolant system over to AN fittings and hose. This replaces the factory heater core return fitting with a billet one that accepts a -12 ORB fitting, so you can run proper hose end to hose end instead of adapting off a factory quick-connect.
Hard black anodized, stainless hardware included.
Features:
- CNC machined billet aluminum
- Hard black anodized
- Accepts -12 ORB
- Stainless steel hardware included
Fits: 2011-2020 Mustang.
The ORB fitting is not included. Complete the install with a Low-Pro ORB to AN adapter fitting in the size your lines run.
If you're plumbing the whole cooling system, the Coyote coolant adapters collection has the rest of the fittings.
BPS part number: EN013
On a car with no heater core, this port is usually routed to the bottom of the expansion tank so the tank becomes the fill point and the system self-bleeds — that routing is covered in the Coyote coolant flow and fitting guide. The other three connections on a full conversion are the front cylinder head adapters (EN011), the water pump inlet fitting (EN014) and the thermostat housing conversion (EN055); all four together are the mechanical water pump AN fitting kit.
