Well, you could disconnect the inlet and outlet heater hoses that connect to the heater thru the firewall. Just plug the heater inlet and outlet, and connect the two hoses together. Of course, you won't have heat anymore. I don't think it would mess up the engine. The steam you see is probably a coolant leak. You probably need to replace the heater core.
