Ok, so I've deleted the A/C and heating system from my 1996 Z28 and I have a wierd questiong about the hoses now. The feed and return hoses to the water pump that used to run to the heater core - can you just cap these outlets off at the water pump or do you have to loop the hoses together now?
I'd like to remove the clutter of extra hoses that I don't logically need now but I also don't want to cause any overheating issues with this. Can they just be capped off?

 

You can do either; plug the holes or run a loop with the hoses.
