Coyote Mechanical Water Pump AN Fitting Kit

Simplify your Coyote engine cooling system with this complete AN fitting kit from Billet Pro Shop. Designed to replace all four major water connections on the engine, this kit provides a clean, reliable, and professional grade plumbing solution using AN style fittings throughout.

Why it helps
Upgrading to AN fittings removes bulky hose clamps and reduces the risk of leaks. This setup delivers long lasting performance for both high horsepower race engines and clean street builds.

Includes

• Driver side head fitting (16AN )

• Passenger side head fitting (12AN) 

• Thermostat housing (20AN)

• Heater hose or water pump fitting (12AN)

Details

• CNC machined from billet 6061 T6 aluminum

• Black anodized finish for strength and corrosion resistance

• Fits all Gen 1, Gen 2, Gen 3, Voodoo, and Predator Coyote engines

What the four fittings are, individually: front cylinder head adapters (EN011, -16 driver and -12 passenger), thermostat housing conversion (EN055, -20), water pump inlet fitting (EN014, -20) and heater core return fitting (EN013, -12).

The ORB to AN adapters themselves are separate: Low-Pro Series adapters in the sizes above, plus spare O-rings. If the mechanical pump is coming off, take the electric water pump kit instead, which swaps the pump fitting for the delete feed. Dry decked heads also need the rear head coolant fittings (EN048).
