What Coolant Hose goes...

[ECM]

on top going to heater core for a m20 engine, not sure if it makes a difference?

I am just about done putting the engine and tranny back in after 5 months of it being out of the car.

Now I can't remember what hose goes on top going into the firewall. Is the T hose or the hose from the back of the head?

Any help would be wonderful. I haven't found any pics that are really clear as to what hose it is going on top.

Thanks

Seems to depend on the year. Back of the block goes to the heater valve pipe.
