Question about 1996 Toyota Corolla

Reopen heater valve

I think the mechanic who repaired my car shut off the valve on the heater core and now I have no heat. I need to reopen this but I don't know how to access the valve. I have a 1996 Toyota Corolla.

    I originally had a coolant leak and that was repaired. As I was driving home I turned the heat on and noticed that it was blowing cold air. In a previous inquiry I was told that the mechanic probably shut off the valve on the heater core to repair the original problem.

    That is why I am looking for the valve to see if that is what the problem is.

I would doubt this very much,you dont say what the mechanic was doing in the first place.if the mechanic was working at the water/heater system then i would say its an air lock in the system a simple air bleed fix this.adrian

We're the shut off valve on heater core 2004 chevy


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.

Where is the heater control valve


I believe water circulates always through the heater core (not on all vehicles, but on yours I think) and flapper doors open or shut to direct air through heater core and to defrost or vents. These doors have actuators which run on engine vacuum collected in a vacuum resevoir and held by a check valve. A vacuum leak, or bad check valve or bad actuator can cause no heat.

Coolant leak near rear of engine.


What is a heating valve please ,never heard of this terminology ,a heater take off yes but a valve ?well if does have one i have never seen one ,most common cause is a core plug or in american freeze plug but a heating valve ?? couid be a heater hose perished and split i agree but a heating valve the heat on these cars is shut off by closing a flap on the heater inside the heater unit so this repair if its just a heater hose shouldnt take long unless its a core plug in which it may involve a longer job

No enoug heat in a 1999 silverado


The cooling system should be flushed but lets start with the heat,remove both hoses from the heater core, install hose to each end of the core about 3 ft long next take waterhose and and start to flush out start with one side and flush with hose on full water, then move to other side , do this a few times, water flow should be clean and flow good, after that if the heat is still warm replace the thermostat and that should solve the problem. good day.

My heater is not heating even though my fan is working. Any ideas on whats going on? I just had my fan replaced last year


Could be your heater valve, heater core, your thermostat (simple, cheap easy fix if that is what it easy).. but since your fan was replaced last year, did you or your mechanic remember to reopen your heater valve? Try the opening of heater valve and go from there, let me know and I will see what else may be wrong.... Or buy a service manual for your year make model of vehicle and it will assist you the service manuals are invaluable and well worth the $$$ when trouble shooting and doing your own wrenching...
If I can be of further assistance please do not hesitate to reply...
Hope my advice helps you out please do not forget to rate/vote or place a testimonial to my advice...

WERE IS THE HEATER CORE VALVE IN 1990 LINCOLN


the inlet to your heater core is dead center of your firewall and 7 inches down. There will be two hoses. The inlet hose is on the right as your facing it. About 8 to 10 inches before the firewall as you follow the inlet hose back towards the engine, there is an inline valve with two wires attached to the top. This valve opens when heat is called for, and allows flow through the heater core. This valve is known for sticking shut. To check it, get the engine warm, turn on your heater, and feel the hose on bolth sides of the inline valve. If its hot on bolth sides you're valves ok. You can also check your flow through your heater core by feeling the outlet hose to the left of the inlet hose. If thats hot your heater core is most likely ok. I have the same car and have a problem with the heater not getting hot. My heater core checks out ok. I think the problem is with the blendor door not directing airflow through the heater core. GOOD TIMES!!!

99 jeep cherokee problem w/ heat I replaced the blower motor, water pump,radiator, thermostat and flushed the coolent system. Still getting little heat. I'm thinking heater core or head gasket... Is there...


It sounds like the heater coil needs flushing out or replacing or the heater valve. Look on the engine firewall and make sure the heater valve is opening. If not open it manually and check the heat level. If that produced heat check the condition of the heater vale cable (or vaccum hose).

No heat


Does the fan blow air, but it's not hot?

For a heater to operate properly, hot coolant must enter the heater core inside the car. A valve opens and closes to allow this coolant to flow and to stop it when heat is not needed. This valve is usually located close to the firewall at the back of the engine. If you had work done on the hoses, it is possible that the connections to this valve were not done properly.

If you can locate this valve, watch its operation when someone in the car turns the heat on. There is likely a cable which runs from the heating system to the valve. This cable will change the position of a lever on the outside of the valve which will either open the valve for the hot coolant to come inside or shut the coolant off. There should be at least two coolant hoses connected to this valve. This cable can get detached from the lever, and this will prevent the flow of hot coolant from coming into the heater core.

Heater


After the car is running for 10 minutes open the hood and feel the two hoses going to your heater core in the fire wall dash area. Are they the same temp?
1) Your temp should be set to high with blower on. If they are the same temp the water is flowing through the heater core. If you still do not have heat the problem is the vet door is not switching from AC to heat . This is located under the dash. THe selanoid door may je jammed, a wire may be off or a vacuum line off to that particular vent.
2) If the temp of the two hoses is different temp one decidedly cooler or hotter than the valve that send the hot water t the heater core is mal functioning. If it mechanically opens and closes this can be corrected by manually moving valve to open. Again if electrical or vacum - check for wire off or sticky vale. If the valve is bad replace it yourself with minimal difficulty.
