What does a Four Seasons heater control valve do?
This four seasons product allows you to add a heater control with the addition of this valve and a pull cable ( like a choke cable ) very easy to insert into the pressure line for your 5/8 hose heater line. We cut out a section of about 2″ to insert these and then mount the cable control.
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 do I know if my heater control valve is working?
Common signs include the heater not working, coolant leaking from under the engine, and no voltage across the heater control valve.
…
Usually a bad or failing heater control valve will produce a few symptoms that can alert the driver of a potential issue.
- Heater doesn’t work.
- Leaking coolant.
- Erratic heater behavior.
How is a heater control valve controlled?
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.
Does heater control valve affect AC?
If the heater control valve fails or gets stuck, it will not be able to allow hot coolant into the heater core so that the heater can operate. If the heater does not have hot coolant the AC system will not be able to blow hot air, and the front defroster may not work.
Does coolant always go through heater core?
The heater core has tubes that circulate hot engine coolant through them before the coolant is returned to the radiator. Air blows over the hot coolant to warm it before it’s blown through your vehicle’s vents. If the air is cold instead of hot, your core might be leaking all of the hot coolant out of the tubes.
Can a vehicle run without a heater core?
Bypassing the heater core may be necessary when there’s a leak in the core. The heater core – much like the cooling system’s radiator – can develop a hole over time, leading to coolant leaking out. Not only the heater won’t work leaving you cold during the winter, but this also means your car will lose coolant.
Why is my car blowing out cold air when the heat is on?
Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn’t just work to keep the engine from overheating: It’s also the source of heat supporting the heating system. If there isn’t enough coolant in your system, the heater core will blow cold air into your car.
How does a heating valve work?
What is a central heating motorised valve? Motorised valves use electricity to direct the water in central heating systems from the boiler to where it needs to be – either to the cylinder coil to heat the hot water, or to your heating circuit to heat (typically) your radiators.
Does a clogged heater core cause overheating?
Engine Overheating
Even a clogged heater core has the potential to obstruct coolant flow enough to cause overheating. A low coolant level (caused by a leaking heater core) can lead to overheating and possible engine damage.
How do I know if my heater core is clogged?

Will my heat work if I bypass the heater core?
No you will not still have heat. The heater core uses the hot coolant from your engine and radiates it into the cabin to produce the heat you feel from your vents. Also a bad heater core is a common cause for the heat inside of the vehicle not working.
Will my AC work if I bypass heater core?
Bypassing the heater core shouldn’t affect the ac system since it should have a valve that closes off flow to the core when its not being used anyway.
Does a bad thermostat affect heater?
A malfunctioning thermostat may cause your heating system to short cycle. Short cycling is the term professionals use to describe what happens when your heating or air conditioning system shuts off too soon, before the heating cycle is complete, and runs frequently.

No heating? An easy fix using a switch on the motorised valve – YouTube
Will a coolant flush unclog a heater core?
Does flushing a heater core work?
Flushing out the tubes in the heater core will allow the coolant to flow more easily so there will always be warm coolant to heat up the air going into the cabin. This is especially true if it has been a while since you last changed the coolant as all the buildup can eventually end up in the heater core.
How do you get trapped air out of a heater core?
Start the engine of your car and allow it to warm up for a while. Once it reaches the operating temperature, the heater valve automatically allows the coolant to flow through the heater core. This action pushes the air bubble outside. Leave the car idle in this state for 15-30 minutes.
