SR20DE S15 coolant flow direction for heater valve? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have an SR20DE S15 I'm swapping into a Datsun Roadster and I'm not sure I'm reading the FSM correctly on coolant flow. I think the hot out of the engine is the tube closest to the block (the larger 90 deg 3/4" hose) but I wanted to be sure. I need to put the heater valve in and I want to be sure on the coolant flow out of the engine. Can anybody confirm which of the two lines coming out of the block/thermostat housing is the hot out?
Thanks!
PS, love to attach a pic but site won't let me (I am approved and file is only 222kb).
