This is a problem you need to pay attention to .
You are not over heating is runs at normal temp and you see no leaks .
Check radiador cap seal .Will it hold 14.2 lbs pressure .Check the engine oil do you see white foem on the filler cap or water on dip stick or engine oil floating in radiator on top of antifreeze .white smoke out the tail pipe .If no then you need a new radiator chevy has this problem it leaks in such a fine mist you never see it .Go to the pressure test has to hold pressure 14.2 lbs
Had two pressure tests done by two different shops. All say is fine. Car has none of the above that your mentioned. Radiator is about 5 or 6 years old.

Check your carpet on the right side if it is damp it is your radiater leaking before changing radiater Inside compartement check for loose clamp on hoses...
It is one of two possibilities. First, the reservoir is cracked. It only leaks as the pressure builds up from the heat of the engine. then leaks out from pressure. Blows out and you wont see the coolant because the air from going down the road pushes it away and the heat drys it up. You have to look for water trails. Next is the hose from the reservoir to the radiator has a leak also. Same applies to this. If it is the hose. replace it, don't just cut some of. When you replace it, make sure there are no kinks in the hose. This causes other problem.
Your reservoir is cracked. I have read your posts. Repace the reservoir, cap and the return line. Your problem will go away.
Car is holding coolant now.. thinking maybe a few air bubbles? But i have also noticed it gets warm on the driver side even when the ac is on. My legs and feet are warm.. any idea what this may be? The ac blows cold but legs and feet are warm?
If you have dual air control, most likely the Blend door motor on the drives side. It is accessible. If you have single control. They use the same plenum and doors for both. On single I have seen pencils stuck in them hold one side open, seen the warped and broken. To see these you have to remove the dash and plenum. If you go that far, I would recommend you replace the heat core while your in there. $20 to $50 part. They do get clogged up.
What are some symptoms my car would show for clogged heater core?
Going down the road or revving it up, you have heat. When it comes to an idle the heat gets less or turns cold. But the same thing will happen if have low coolant or haven't purge the air out of the system.
Thank you. I believe i had a couple air bubbles. It is now holding coolant like it should. I drive 80 miles a day on it, 40 to work and back. All seems to be fine so far. No coolant light, not getting hot, although it gets warmer than normal sometimes when sitting at a light or in traffic but quickly goes back down to a little below half way mark. When i say it gets warm it goes over the half way mark not to the next white line, then goes back down below half way mark I'm assuming when the fan kicks on... it has 94k miles on it
Yes , this is normal. Half way mark is good, Around 200 degrees. Up and down is normal also. Fans and T stat working. Sitting at lights and such, temp can and will get to 225 degrees. When it gets into the red is when you need to worry.
I have a question. . While driving my car i have a vibration on the steering wheel and can feel it in the seat as well on the passenger side. The odd thing is, is I can feel the vibration building, it vibrates, then goes away, about 30 seconds later, i can feel it building again, vibrate then goes away. This goes on while driving and you can notice it the most on Highway driving. Its just strange how you can feel the vibration building, like it starts out real slight, i know its coming, then goes away, feel no vibration, then it builds again. Strangest thing! Any idea on what this could be? I did the tire rods and boots and all that a few years back.. any thoughts? Thanks again for all your help!
I would be looking at the suspension and steering. Ball joints, outer tie rods, and inner tie rods. Even new tie rods can fail. Setting still, turn the steering wheel just a bit and feel for a slight click. This would tie rods, inner or outer. This would cause a slight vibration and it would come and go as the car is swayed back and forth. Even in a straight line the car will go left to right slightly. When the tire is going straight and doesn't have a left or right drag on it is when you will feel the vibration. Ball joints don't do this as much, but can contribute to the problem.

Water pump
If it is the water pump, wouldn't that show when under a pressure test?
Yes.
Ive had two pressure tests done by two different shops.. not water pump :(

There is either a pocket of air or the car is burning the coolant if there is no leak. check inside the car for any coolant leaking under the dash if so the heater core has a hole in it.
I have had the car pressure tested twice by two different shops. They cannot find anything. Nothing under the dash and no coolant smell inside the car?
Last night we filled reserve took it for an hour drive, came home coolant in reserve, woke up today to check coolant.. reserve empty...?
are you sure radiator is full when car is cold, not reserve, but actual radiator?
Radiator is full with coolant, one of the fist things we checked.

Ur coolant level sensor might need changing. If not, the circuit associated with the coolant level sensor needs to be inspected
SOURCE: 2000 Monte Carlo SS (89,000 mi)
That slushy brown stuff is signs of a blown head gasket. Have a code scanner hooked up to find out why the light is on, it will probably show coolant temperature sensor. Just out of curiosity, check the pvc valve (if your car has one), and see if it's clogged. If it is replace it, the crank case is not getting ventilated.

this vehicle is equipped with a factory anti theft system if when you try to start the engine and the anti theft light is on then the starter won't start even if your check engine light is not on you would have to scan the body module to pin point the problem to see if it's the anti theft system or the starter, go to a auto parts store like auto zone or pep boys or western auto these store offer free scanning to there customers. if this information has been helpful please let use know good luck

It sounds like an engine temp sensor is open.. When your engine is cold or anti-freeze is cold your ECU or ECM gets a signal from the temp sensor for cold engine start. It would make sense that it works fine when hot because the resistance on the sensor is a lot lower. Take an ohm meter if you have one and check the resistance across the temp sensor pins. When the engine is cold the resisitance should be really high. Start and warm up your car to normal temp and check it again. It should be a lot lower now. If not replace it. Hope this helps.

Hi;
If your engine cools down when moving fast, you either have a problem with your water pump or your electric fans that cool off your radiator and a/c condenser. This is controlled by a temperature switch, but these fans should kick on instantly when A/C is selected.

Carpet stores really cant help.

if a pressure test showed nothing and there is definately no leaks then it is either burning coolant at a small enough rate that its not showing out the tail pipe or you have an internal leak in the engine. what does the oil look like. if its a milky colour and possibly over full on the dipstick then its an internal gasket or corroded metal problem.
Oil looks fine.. one of the first things we checked as well
