Can you bypass heater control valve?
Heater control valve bypass is not standard on vehicles; it is a modification. When bypass hoses are installed, the coolant in your car will always be circulating through the heater core – that means that if the core starts leaking, you won’t be able to turn it off.
How does a heater control valve work?
The heater control valve (sometimes called the hot water valve) is used to control the rate at which coolant flows through the heater core. The valve is located on the heater inlet hose. Manually operated systems may use a cable, a vacuum motor or an electric solenoid to operate the valve.
How many ohms should a gas valve read?
Test the coils with an ohmmeter with the wires disconnected (you only need to disconnect one wire on each coil) and you should get around 40-60 Ohms resistance at the two leads of each coil. If the meter reads much lower or much higher then the coil is bad and needs to be replaced.
Does coolant flow through heater core when heater is off?
When you turn on the heat inside your car, air blows over the heater core, is warmed and comes into the cabin. Some vehicles have a heater valve that directs coolant through the heater core when the heat is on and bypasses the heater core when the heat is off.
How do I know if my radiator is circulating?

Do I need to chock the wheels when working on my Ka?
As with all jobs, when working on your Ka, make sure that it is secured with handbrake on and in gear so it cannot roll towards you or away from you whilst working. If in doubt chock the wheels to make doubly sure that it doesn’t move. As you will not be working under the car I wouldn’t say there is need to chock the wheels at this stage.
