Keep looking - there isn't a shut-off valve for the heater core. Water flows through the all the time. The only time you get heat is when you set the controls for it and then cabin air is routed through the core. All other times it bypasses it. If you have a leaking heater core, in most cases you can remove the heater hoses at the firewall and using a hose adapter available at any hardware store with a couple clamps, you can make a bypass loop of the core until you can get it replaced. Of course you have no cabin heat until you repair or replace the core. It is not recommended to stub off the ends of the heater hoses because on some vehicles, that loop provides other cooling functions such as cylinder heads, etc. That is why looping it is the safer choice.

SOURCE: need to know where the heater core and heater

The heater core is on the passenger side under the dash within the heater airflow contoller box. If you had Xray vision and could look straight through the glovebox, then you would see it. The heater control vale for the water flow is on the passenger side top of the engine near the firewall. It will have a domed top with a vacuum line to it and it is placed into the heater core supply hose.

SOURCE: 2004 Chevy Impala no heat from defrost or heater

No heat is often a symptom of low coolant, usually followed by overheat. There are other controls that regulate heater, but right now, re-fill the cooling system with engine running and heater on high, then check for leaks (coolant you lost went somewhere...you need to determine where) Low coolant will damage your engine. Take care of that first, then if heater still does not work, then do diagnosis on that. (if you loose the engine heat won't matter, will it!)

04 ford explorer heater blows cold coolant does not circulate


Number 12 is heater control valve. Number 11 is vacuum line, full vacuum and the valve will shut off coolant flow. I can't say the valve is the problem? Maybe the heater core needs to be flushed? When you say coolant doesn't flow, you mean through heater core?

The heater on my 2004 mercury mountaineer does not work. When turning the dial from ac to heat, cold air blows out while a sound like a door opening and shutting is heard.


there is a vacuum ran valve on your heater hoses goin in to your heater core on the fire wall, they tend to get stuck shut n dont open to let hot anti freeze in the heater core, so cold air right, qwik fix is find the valve on heater core inlet and wire tie it open so antifreeze circulates no matter what, this is known on ford explorers. pretty much same truck.

once truck is warm check both heater core hoses to make sure they are both warm if not then check the cold water valve could be stuck shut not allowing coolant to travel in to heater core.

Heater does not work on my 2005 chevy impala ls but the blower does but blows cold air


If you car is coming to temp but you get nothing from the heater the first place to look is the coolant valve for the heater core. It is sometimes called a mixing control. See if the control is jammed or your control cable is frozen or disconnected from this valve.

The valve should be somewhere near the cooling lines leading into the heater core. I am sorry, but they may be under the dashboard as well.

Good luck and be careful.

HEATER CORE


Going to your local public Library would be best at this point.
Also,,i should warn you that replacing the heater core is a difficult job for someone inexperienced, and even when you know what you are doing, it is difficult.
