I am trying to put this car back to as original as possible. I was able to get my heater hose's hooked back to the way there supposed to be, but I need to know what is supposed to be hooked up to the left side of the intake cover outlet? there are no capped hoses or valves anywhere around that area. Also will my heater still work if I just cap that side of the intake?

Thanks

 

What is this?

 

as you look at the front of the engine above the water pump there are (2) hose outlets under the intake manifold, the one on the right (passenger) side connects to the heater hose's, the one on the left side has nothing attached to it, I was needing to know what is supposed to hook up to it as there is nothing on the water pump or anywhere else I can see. I took a picture but it is to large to attach.

 

I think you are referring to the bypass hose. The coolant comes from a nipple on the front of the intake to the iac coolant plate and out to the heater core.
