Hooking up a heater

[Dave]

There is a water hose that goes up and across the top of the engine that comes off the bottom radiator hose right before the water pump. It makes a u turn at the back of the engine and goes to what im not sure.
(A cooler for something, pardon my ignorance).
Can I use that to hook up my heater through the dash?
It looks like it goes to the back of the engine for just that purpose. As well as the four plugged holes in the firewall for access.
Also, I think the flow must be running right to left as you are standing in front of the vehicle?
Any help would be very appreciated!

Flow runs left to right from standing in front. That is the egr cooler and that would be a good place to tap for a heater

Thank you very much!

If you will connect your heater core inlet directly to the egr cooler at the outlet closest to the firewall, this should net you the most heat. Then tie the outlet of the heater core to the factory hose that was taken off of the egr cooler.

Thanks for the info!
