Is there any problem In capping out the coolant outlet and inlet for the heater core?

 

The engine doesn't care.

 

good. that's all I want to know

 

Only if you want heat

 

Consequences: No heat, no defrost. If you drive in a cold or humid area, this is a really bad idea because it is difficult or even impossible to clear the windshield of ice or refreeze on the outside or condensation (fog) on the inside. Otherwise, it doesn't make any difference.

 

well my defroster/heat didn't work in the first place lol.
