Q: Where does the coolant surge tank hose run?

A: At the left side of the water pump, there are two hoses that come out: 1. A hose towards the front of the engine that immediately splits into one that goes to the heater core, and the other that goes tot he coolant surge tank. I’ve got this one running to the right side of the heater core.

Q: Where is the heater core inlet hose located?

A: One of the fittings[the passenger side of intake] goes to the heater core inlet. The hole on the Bigger hose = outlet, smaller hose = inlet. Currently the heater hose goes from the driver side front on the intake.
