What are these connections for? Why are they tied together with the valve being open? Are they the connections for the heater that I couldn't locate? One is on the water pump, one is on the lower part of the block starboard side.

The hot supply should be coming from the intake manifold, and returning to a T before the RWP or the block. It also seems to work well returning to the U pipe out of the thermostat housing. This is the common Ford setup. The return on a Chevy with a knock sensor would be off the circulation pump as you seem to have. your setup is messed up, it wouldn't be very warm even if the heater was connected. ------------- |

| I guess I didn'T give enough info, this is a gm 350 apex. The heater is factory but the coil was busted when I bought it and the lines are there but just laying under the motor. On your picture, the line connected to the manifold on yours, my manifold has a temp sensor in that location, and to turn a 90 elbow into this location can't be done because it would hit the fuel rail. So could this be why the other locations where used? Also is the manifold the supply side to the heater and the pump connection the return? Which would the connection I have at the lower side of the block be? Supply or return? On your picture what is the blue line tee'd into that line in the background? |

Start phoning big dealers in the north and see if you can find one that has any experience with this application. I just don't think the current setup would provide much useful heat. Perhaps you can fit a nipple/pipe or a 45 elbow and then a Tee. How about a few pictures of the manifold port area? ------------- |

Of course not. You could hook it up to the raw water supply and dump the outlet overboard.  ------------- |

This conversation is useless without a fundamental understanding of hydraulics. ------------- |

You two are both clowns! No one is asking which is supply and return on the heater core side... of course it doesnt matter which way the water flows through the core. Not sure why it was implied that pulling the feed from the block would provide inadequate heat. Block and intake manifold are the 2 most common places Ive seen the feed tied to. Intake might be better since its last in the cooling loop, but block should be fine too. Return can be plumbed to the rwp or circ pump, seems the OP's set up uses the latter. Nothing wrong with that.
The answer to your question is yes, those are the heater connections. Theyre probably tied together in order to bypass the broken core. Putting a hose between them would be the easiest way to do that... way easier than removing the barbs and replacing with plugs. I suspect it doesnt matter much whether that valve is open or closed. ------------- |

And then there were 3 clowns. Both of those ports have positive pressure. Which ever one is higher pressure will be the supply. I can't say for sure which one that actually is. ------------- |

Bingo. Return before the RWP. ------------- Tubing Sucks. |

That may be ideal, but thats not where PCM/CC puts it (they use the circ pump for the return). And the factory heaters put out great heat. ------------- |

Anyone with factory installed heaters please chime in. Year/model/engine ------------- |

| So let me get this straight, the block and the intake manifold are both positive pressure. So the other side needs to go to the small connection on the water pump referred to as RWP. The pic that I posted shows the line connected at the water pump, isn't this the return side of the pump? The only discharge off the pump goes to the testator housing, right? |

I'm just going to give a resounding no to most of that. You have some reading to do. ------------- |

when my heater core used to leak I just stuck an elbow in one hose and then to the other hose to bypass the heater. why not just hook it up? ------------- This is the life |

Well I guess I will. I can't test it until spring and I wanted to make sure that it was correct while I had time to do it. |
