okay so i eliminated my heater and looking at the fsm the heater has a coolent line on the lower readiator and a coolent line on the right side of the block looking at front of motor. so can i jsut plug up these to lines and not run them?

 

yes you can just plug them but make shure that you use good plugs or they will eventualy crack and leak

 

I had them looped for a while then plugged them both up when I swapped my motor.
