i am in the middle of installing my new engine, its a built b18b in a 99 integra and im a little stuck with the coolant lines, my plan is to run the throttle body without the cooant lines going through it, but im not sure how to rought them....

there is a nipple on the coolant cross over (the pipe along the back of the block with the thermostat) ... normally that goes to the idle air control valve (back of manifold), then to the throttle body, then to the charcoal cannister (under battery) right???

should i just loop it from the cooant cross over straight to the charcoal cannister??

or should i weld the nipple shut on the coolant cross over??
