I don't know the exact hose routing for theses cars, especially the heater core routing due to the unneeded intricacy of the diverted valve, but I'm not sure if heat coming from the water pump would work that well.
Are you saying both the intake and return line from your heater core are attached to your water pump? And if so, are there two separate holes to attach to or is it being split after it comes from the water pump? My water pump only has one line to attach it to.
I would think the water pump would pump coolant out of any hose attached to it (unless it's coming from the suction side like the lower intake hose), so if two hoses were attached to it both going to the heater core, they were counteract each other and there wouldn't be much flow if any. If two hoses were split from one line, then it definitely wouldn't work.
Maybe it's set up differently in your car than I'm picturing though. However, the coolant coming from the water pump is going to be the coolest in the system since it just came from the radiator. It should still be hot enough to give heat though..
With the water pumps I've had for my engine, I think they only way they can be set up to pump water correctly (if using the water pump) is to have the top bung be used to have coolant come out of the water pump to the heater core, then route the other hose to the small coolant intake on the radiator or any other section that acts as a return to the radiator.
Yes both hoses are going to the pump using two different ports in the pump,1 on the top and one on the side of the pump
Would it make any difference if I switched sides?If not I'll have to change the brackets to raise the AC Compressor so I can get to the intake plug
Thanks for your input,I really appreciate it
Hmm.. Well I'm not familiar with that style pump but it looks like the one on the side may be a suction side, while the other one is probably an outlet, which if that is true then there should be good enough flow.
For switching the hoses, I don't believe that would do anything if both hoses just go directly to the heater and back. I think the heater core is set up so it flows pretty similarly through either direction. I believe one side is supposed to be the intake, while the other is the outlet, but I don't believe there is going to be much of a difference besides on side coming in from the top and the other exiting from the bottom on the core. (Lot's of believing going on here so you can tell I'm not 100% sure, but I think that's how it is.)
I don't know how well you can feel heat through that style hose, but if you can, I would test to see if they are getting hot during normal operating temperature of the vehicle (and compare it to the lower radiator hose as well to make sure that is heating up also.) That way you can be sure if there is no flow through those hoses or not and see if there is flow that the temperatures are hot enough. Or, you can take both hoses off the heater core and try and dangle them in a bucket, then turn the car on and see if coolant is coming out of one (or both) to make sure there is flow. If it comes out of both hoses, then that would mean the flow is opposing itself. That way may be a little messy though...
Your setup looks pretty nice, so I don't think you would want to reroute the hoses or maybe don't have the option to based on your manifold, but they way mine is set up is there is a coolant outlet on the back passenger side of the intake manifold in between the oil breather on the valve cover and the distributor. That side goes into the heater core, then the other end goes into the top of the radiator. I do have the heater diverter valve still on mine so it is directed in obscure ways, but that should be the way it flows when in operation on my car.

Thanks for the help BubbaI took the top hose off the W/P and rerouted it to the intake manifold .It's kicking now!!!
