On a B18a1 OB1 from a 93 Integra. It's actually swapped into a CRX if that matters. The one below the coolant inlet. I'm doing a B swap and I think I have all the coolant lines routed correctly but I don't see where this one would go. I am following the diagram below and I can't tell where it is supposed to go. It looks like it goes to the bottom of the throttle body but I don't see any extra places to hook it up. One goes from my MAF (i think?) to the rear of the engine and the other side of the MAF is looped to the bottom of the throttle body, from there it goes to the tstat housing. Then there are two lines from something else on the bottom of the intake that go to the T stat housing.

 

Heater core inlet hose.

 

I think that's the one above it. I'm talking about the one that already has a piece of hose connected in the pic above

 

these hoes aint loyal

 

Hoes go wherever the $$$ is.

That hose goes to the Throttle body.

You want the diagram for the B18B1 not the A1

 

Goes to bottom of the throttle body, to the Iacv then from Iacv to the back of the block I believe to the water pipe that feeds the water pump, some year models have 2 ports and some have 1 if I'm not mistaken, as well as certain year engines came with a fitting on the thermostat housing and some not. On my gsr I believe it's like that and on my Type R motor it doesn't, I deleted those hoses completely as I don't need them cause there there for cold weather areas where you need the coolant to keep the iacv from freazing, my after market throttle body doesn't have the lower ports for the coolant so that's why I deleted those on my ITR engine, your LS is a bit differently setup but similar as far as the coolant hoses from there to the iacv to the back of the engine.
