After removing the heaters...

I removed the front and back heaters. As far as I understand, it was helping with defrosting the front windshield and providing coolant for the engine in the back.

1-) Front: May I leave it without looping the pipes? If yes, what are the cons of it?

2-) Back: Does shutting the valve enough to provide coolant for the engine, or should it be looped back for engine to work properly?

Thank you very much.

The heaters don’t cool the engine, well they can but many people including myself shut the valves in summer to help the inside stay cooler.

You can remove the front heaters if you enjoy being bundled up in layers to drive in cold weather and manually wipe your glass down in cold rain
