How can I get water through my cab heater?
You could shut the valves, pull the hoses off the valves, and run water from a garden hose into the cab hose to get most of the air out. Another good way to get water through the system if you have one is to use a pressure tester. Shut off one valve at the block and pull the hose off that valve.
How does a heater control valve work on a car?
Here a fan forces air across the surface of the heater core and then into the passenger compartment where the warm air is felt. During times when the air conditioner is in use, the heater control valve closes, preventing engine coolant from entering the heater core.
