Well you cant just block off the hoses, you have to keep the coolant circuit intact or bad things will happen. You can take the heater out of the loop but you have to be sure to route the heater hose back into the engine.

so can i just connects the "u-shape" hose to go back into the engine like in a "u" route so example, from where the coolant comes in, get a hose to immediately have the coolant run back to the other nipple that receives the coolant?

As long as I'm correct in thinking that the heater core has coolant passing through it whether its on or off, then yeah, doing a tube from the coolant output to the coolant input should do it for you.

If by chance the heater core does stop the coolant flow through it while it is off, then you would need to block off the hoses without recirculating them.
