Question about 2004 Oldsmobile Alero
I replaced the water pump, thermostat, and coolant sensor, but my heater doesn't get warm if I am not riding, car doesn't over heat but the water isn't circulating what's going on
You need to bleed the air out of the cooling system. Google a search of the way to do this.

When you say not leaking antifreeze has your coolant level gone down at all? and is it that you have seen no leaks where you park it? What worries me is you can smell it when warming up, have you felt the interior floors to see if damp and do you get any condensation if put blower onto screen, if so then heater matrix is leaking if not could be down to headgasket and/or cylinder head leak.

SOURCE: low coolant light
I have a 97 Cutlass. The low coolant light is on as well. After talking to some of my mechanic buddy's this is a know problem with this model of vehicle (Cutlass/Malibu). You can either replace the coolant reservoir with the sensor or just ignore the problem as even with replacing the parts it is likely to come back on.
Hope this helps

SOURCE: coolant not circulating
I assume you know that the only circulation happening unti lthe thermostat opens at its nominal temperature is through the heater core if in use.
If peering into the radiator opening, you will not see more than the most minimal movement until the thermostat opens.
You may have an airlock in the system and it could be in the heater lines so if you have done a coolant change or had the system open, you need to purge the system of air.
If you have no radiator cap like many newer vehicles, this isn't as easy to accomplish. You will have to pass through several cycles of warmup and cool-down and each time refill the reservoir to the marked level with coolant mix. During this, you will have to have the heater control set to warm the interior so that the coolant is forced to circulate throughout the whole system.

I have and 98 Intrepid 3800 motor, and had same problem.
I tried a few things, but what finally worked was when I took the car for a complete cooling system flush, they opened the radiator and cleaned every single passage line, flushed motor and heater core,
It cost me about $100 but I havent had a problem since. I recommend you do the same.
There is a screw on the thermostat housing that is used to purge the air out of the cooling system. On your owner's manual are detailed instruccions of this procedure.

Hi there camcam,
Ok, first off the cooling system has to be full and circulating for the heater to work. When we get the rest of it solved, the heater will take care of itself.
Now the overheat problem. We need to determine if the engine is overheating because of lack of coolant or the lack of coolant is because of the overheating (Boiling off).
If you have to put in any significant amount of water on a regular basis, it has to be going somewhere. If there is a pool of coolant forming under the car, there's a leak. You need to locate it and act according to where you find it.
A malfunctioning thermostat doesn't allow the heat exchange process, the engine overheats, coolant turns to steam....
Although rarer, the same result occurs if the water pump does not circulate coolant. When a water pump fails, it's usually leaking through a shaft seal.
So, if you don't find a leak, the thermostat is the first (and least expensive) thing to address.
I hope you find this to be instrumental in solving your problem.
