To achieve the desired accessory-drive belt path, the Coyote's water pump rotation was reversed and the thermostat housing was incorporated onto the pump casting. The O-ringed housing bolts to the round boss on the right of the pump, as seen here. The engineers say the coolant path through the engine is important, but what direction the flow takes is not. You might not think the water pump has much to do with the throttle body, but the reason the drive belt path needed attention was to package the center-mounted throttle body as low as possible.
