It's worn and sticking, once it gets hot enough it breaks loose and opens then it sticks again until it gets so cool that it breaks loose again, closes and lets the engine warm up. Replace the thermostat before you overheat and cause severe engine problems.
you have to bleed the system it sounds like it has air in it so you need to locate the bleed screw which is normally on the thermostat housing
Souns like a head gasket to me.
heater core could be plugged, also check for low coolant
You are in the beginning throws of blend door failure. Check www.heatertreater.net for more information on diagnosing and fixing the problem.

Possibly a faulty coolant pump.
it maybe your heater core is going out recommend replacing it and go from there
No ------------------------------------------------------------------------------------------------------- The spring side of the thermostat goes towards the engine, and if the thermostat is installed vertically the vent hole goes at the top. Helpfull
you follow the top radiator hose to where it goes to head or intake and remove it and remove the neck it was on the thermostat is under there and replace it with a new gasget and a little rtv to make sure it dont leak hope it works 4 you it is a simple job just take your time
bob is the best
Check coolant level in RADIATOR when cold When light is blinking turn on heat and see if you have any. If no heat good indication that thermostat is stuck in closed position and needs to be replaced
The spring side goes TOWARDS the engine , and if the thermostat has a vent hole it goes to the top if it is a vertically mounted thermostat
The spring on the thermostat goes down towards the engine.
This is probably an indication that your thermostat is stuck open. Go to a radiator shop and ask them to test it.
because in the day time the hot air from the beech blows on the lnd and at nightthe cold air comes to the city and the warm air goes to the beech
The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.
heater not hot
The spring goes towards the engine , and if the engine thermostat has a vent hole , the hole goes at the top
The spring side of the thermostat goes towards the engine.
It either has to do with your antifreeze being extremely low or your thermostat went out. I have a 95 Beretta and every time (as in fairly often) my thermostat goes out in the winter, when I turn my heat on it actually blows snowflakes into my car. First check your antifreeze level, If this is not the problem, then locate your thermostat, it would typically be where the upper heater hose connects to the engine. A replacement at your local parts store shouldn't run more than 6 bucks, and with a set of wrenches, pliers, and the internet you should be able to change it yourself in about 15 minutes.
No. That sounds like the temp blend door actuator is on its way out.
On the 3.4 V-6 Chevy Malibu the thermostat is located at the rear of the engine. The exhaust cross over pipe that goes between the exhaust manifolds makes the thermostat housing hard to access. The easiest way to change this thermostat is to first remove the exhaust shield and exhaust cross over pipe, then the t-stat can easily be changed. After changing the thermostat, be sure to bleed the air from the system, look for bleeder screws and run heater until air blows warm.
