It very possibly could be the actuator that controls the valve that allouws hot water to flow through the heater core. If the out hose is cold then there is none or not enough hot water flowing through the core itself. If you are sure the cooling system is full and you are sure the core is not leaking (you would smell the anti freeze if it was leaking very much at all) then the only thing left is flow and if the water pump itself is working as it sould then I would say either the core has something restricting the flow and that could be a hose that has a kink, or a blockage of some sort(rare but it happens) or the heater control valve is not functioning as it should so the valve isnt opening (I think its controlled by a vacume line going into the back of the knob that is on the dash. I had a 97 Tacoma V6 and the heater would literally melt you to the seat. If you check all that and dont find a problem then I would like to know what you do find if you ever figure it out. Hope that helps you at least have some places to start.

Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.

you could try running engine and open top heater core hose highest point should bleed it fully, failing that look at manual should tell how much water is in system

2007 toyota camry LE 2.4L does it have a heater control valve?

There is a blend door in the heater box in the passenger compartment. This door mixes the air from the outside and routes it through the heater core. If it is stuck, then no air comes through the heater core. Check for the levers under the dash by the center console and see if they move.

How do i remove the heater core hoses on 2004 toyota camry LE 2.4L?

You have already been told that there is a VALVE in control of your heaters water flow...THE OTHER NAME of the heater core is a heat EXCHANGER... It delivers HEAT to the passenger compartment... In so doing the water returning to the ENGINE will... BY THE NATURE of plain/pure PHYSICS, be cooler...!!

The (unstated but) very SIMPLE question here...
The heater is NOT working...??
Check the VALVE.

You already know where the water goes in... and comes out There's no need to remove the core for FLUSHING.

One (return) heater hose being cooler is as normal as the sun rising in the EAST (it is not a problem... by itself)...

Why it take a long time for the engine to warm up?

You may have trapped air or exhaust gas preventing water circulation. This may be a sign that the cylinder head gasket is leaking.

My in heater in a 2007 grand prix doesnt work the air blows but isnt hot temperture gauge looks fine an have changed out thermostat

You have a plugged up heater core. Try pulling the heater hoses of where they go into the firewall, put a garden hose with a spray nozzle in one hose and gently flush the system out. you will need to pull both heater hoses off to do this.

I have a 1992 toyota camry le with a 3.0 v6. I'm having an issue with the heating system. It blows somewhat of warm air and not hot air? The engine warms up to normal operating temp. Do i need to change...

I would start by checking the hoses at the heater core. One should be hot the other cooler but still pretty warm. If one is hot and 1 is a lot cooler you probably have a plugged heater core. You can also check to see if you hear the blend door slamming and check air temp change when you switch from full cold to full hot. If there isn't a clunk at full hot or cold the door might be stuck.

J ai un probleme avec le chauffage de ma taurus 2002 remplacer déja radateur de chaffrette ainsi que le termostat et le ventillateur de chauffrette ne fonctionne toujour pas help please

Check the heater flow valve to make sure coolant is actually flowing in and out of the heater core. With the engine at full operating temperature turn the heater control to HOT. Feel the hoses going to the heater core. One hose (Inlet) should be very hot and the other hose (Outlet) should be very warm. If the outlet hose is not warm then you have no flow of coolant. Check the flow valve.

92 camry, no heat and when engine warms up it wants to die. Changed thermostat but no difference could it be a plugged heater core?

At the firewall, in the middle there are two heater hoses coming out of the heater. With the car warm, turn the heater on to the full hot position. Feel the hoses. If the one with the valve in it is hot between the valve and the firewall and the other one is cold after a minute of the heater being on, then yes, the heater core is stopped up. If both are hot, then the problem may lay with the blend door (cable operated) inside the car just to the right of the accelerator pedal.

Heater not blowing cold air not warm or hot

A heater core only needs to be changes if it is blocked with rust or is leaking, a more plausible reason would be a stuck open thermostat in the engine cooling system. Also check under the hood for hot coolant in and out of the heater cores hoses, those are the small hoses going to the firewall and into the truck.
