What could cause your heater to not work even though you have proper coolant levels?

The thermostat may be stuck in the open position, so that the water is not getting hot enough.

Why would water not flow though the heater coil?
Heater core plugged? Heater core airbound? Thermostat not opening to allow coolant flow?
Marine engine can be used in a car?
Sure. The engine coolant loop might be a bit different though, you may have to get creative to hook up the cab heater core.
Why does the heater not blow hot in a 1997 dodge stratus?
It is possible that the thermostat is stuck open, thus not allowing the engine to reach sufficient higher temperatures for proper heating, or the water pump may be too slow (or stuck) to allow the proper coolant circulation through the heater unit, or the switch/flap "controls" (or vacuum system) to the heater unit may be faulty (or stuck) so as never to engage into "heat" mode, or the heating unit/coils may be so clogged that it is no longer effective for giving off hot heat, even though the coolant temperature itself is hot enough, or you may have the wrong thermostat for that vehicle (thermostats have different operating temperatures per specific vehicle).
On a 96 S-10 Blazer why would there be only cold air coming from the vents even though the engine temp is norm at 240 deg?
Your heater core may be clogged. Have the heater core flushed and refill the system with fresh coolant.
Why doesn't the heater in your 98 Chevy 1 ton work you put in a new heater core and the coolant is clean The overfill tank won't hold any fluid though Please respond before it gets too cold thnx?
do the heater hoses get warm? please advise. Justin25taylor@yahoo.cm
99 z71 heater blows cold air?
Further information is needed to make a proper diagnosis (does the truck over heat, is it leaking coolant?). The first thing to check would be the thermostat. If the thermostat is faulty (stuck) it won't allow proper circulation within the cooling system which can prevent your heater from blowing hot air. It could also be a bad heater core, either leaking, or plugged. Often if the heater core is the cause, you will smell antifreeze or even see it on your windshield in some cases. You could also have a low level of fluid in your cooling system, or a lot of air built up and trapped within the system which prevents proper circulation. The water pump could be faulty as well, or the belt powering it may be to loose and slipping, or installed incorrectly. With the water pump though, if it's faulty then it should be leaking coolant. If the belt is the problem, then you should still get some heat during highway driving.
The blinking lights that mean your coolant level is low came on even though the coolant level was proper; you drained the radiator and refilled only 3 litres and the light still blinks?
Either the reservoir is low or the sensor is bad.
How does a car heating system work?
The water pump on the engine circulates coolant though the engine, radiator and heater core (which is usually located under passenger side of dash). The heater core looks like a small radiator and once the engines coolant starts warming up thr heat can be spread by the blower motor mounted to the side of the heater core. Voila! Hot air blowing out of whatever vent you choose.
How reliable is the Cadillac Catera?
not very, lots of quirky items with coolant loss via heater control valves or engine oil coolers. Nice cars though available at a great price.
How can excess levels of carbon dioxide be harmful to plants even though it is the primary compound they require to survive?
It is a Question of keeping the proper Balance of the various Reactants.
How to change heater core in a 93 Ford Explorer?
I have a '91 and I believe they're about the same though. The heater core is back inside the glove compartment. You'll probably have to remove the door/tray itself. To get it out you have to disconnect the coolant hoses going through the firewall (engine side). After that there really shouldn't be much to it.
What is the process of coolant filtration?
The process of coolant filtration is actually a somewhat complicated process. Basically though the coolant filters allow recirculation and reuse of liquid coolant.
