-You don't drive the car especially if you have a coolant leak inside the car.

I drove my car for 2 months (while sourcing a new heater) with the only interior part fitted being the drivers seat and empty dashboard, you can do the same by bypassing heater and getting a some roughly 1" diamater, 3 inch long metal pipe and joining to the 2 (inlet and outlet) hoses to the pipe I just mentioned.
