There is a tech article on the home page about bypassing the throttle body coolant line. Yes, you DO need a PCV valve. Hook it up to a good vacumn source and run it to the top of the valve cover.Heater hoses: Run one hose from the radiator outlet located on the left tank on the radiator(should have a fitting) to one side of the heater core. Run the other hose from the other heater core outlet to the fitting located on the front of the engine behind the water pump. It comes out of the intake manifold. Thats it. Left tank looking at radiator from front of car.Actually right tank! My bad.
