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!

The heater doesn't care which way the water goes through it. Is easier to bring it off the waterpump on top the engine, run it through one of the ports on the right and bring it back through a port on the left to hook it up. Be sure to let the water flow and not shut the heater valve off as it will restrict the intercooler. The heater will be warm, but if the fan is not blowing it is fine. In summer the heater can be bypassed.

Heater hose routing question

Can someone tell me if I have my heater plumbed backwards? After reading Mopar93’s excellent post in another thread I judge I may have the intake and return backwards. 2019 Roxor with Summit Racing 260 cfm, 28,000 BTU heater does not produce heat. A warm sensation occurs only! Red arrow...

This was my experience with a Summit Racing purchased heater. Hope that helps
