Coolant in coolant reservoir did not fill low level in radiator

1985 Audi 4000 S Quattro. Owned for 3 years, bought new radiator 3 years ago. Coolant temp sensor intermittently on, looked in reservoir, 1/2 full always, never went down. Finally looked in radiator, needed to add about 1.5 quarts, now light not flickering. Why isn't the coolant in the reservoir not topping off the level in the radiator?

You must drain air out of system
so when engine is warmed up, just unscrew slightly the thermo time switch which is the highest sensor and unit in cooling system besides the reservoir, until alittle air releases then when antifreeze starts coming out then retighten to specs. BE VERY CAREFUL !!!! LOOSEN VERY SLOWLY AND NOT COMPLETELY REMOVE FOR THIS CAN CAUSE BURNS. MIGHT WANT TO USE A RAG AROUND SENSOR. If this doesnt solve it then make sure you have the correct rad. cap. Also that the filling hose is not clogged as well as the little port on radiator.

If there was an air lock this would not allow the reservoir to bleed out into system.
it sounds like it wasn't fully bled when the new radiator was put it, it can be tricky sometimes to get all of the air out.

The CHECK COOLANT indicator illuminates when the coolant level is low in the coolant recovery reservoir. The low coolant level switch is probably in or on the coolant reservoir !

Why is the low coolant light flashing?
The low coolant light is operated by a level sensor located in the coolant reservoir itself. If the low coolant light is on and the coolant level is full then wither the sensor is unplugged or the sensor is bad.

You have air trapped in system , change thermostat , bleed air from system , let it run hot while adding coolant with blower full blast on all front and rear heaters .

Engine is too hot, water circulation n radiator okay.
Check the coolant reservoir tank and fill if needed. Most modern cars have a plastic reservoir of coolant connected to the top of the radiator. This will allow you to see if your coolant is low. Many have marks indicating the proper level of coolant when the engine is hot. Check to see if the coolant is at that level.
Add coolant (or water, in a pinch) to your reservoir to the full/hot line. On most cars, you can add liquid to your reservoir even if the car is hot. Check the owner's manual to be sure, or wait for the car to cool before opening.
If your car only has a radiator and no coolant reservoir, you must wait for it to cool before checking the level of coolant.

Coolant reservoir is overfulling after being driven
It probably got overfilled at some point. There's a max line on the reservoir that you shouldn't fill it over. Coolant expands as it heats up so if there's too much in the system, it's normal for it to overflow.

My Chevy Venture 1999 when I drived the temperature was normally, but when I stay the temperature was hot. I changed the termosthator but the problem is continually.
Check the coolant reservoir and the radiator for proper coolant level. If low you probably have a leaking intake gasket or possibly a head gasket leak. The intake leak will be visible on either end of the intake manifold, located at the very top portion of the engine. The head gasket usually shows up at the rear head, nearest the belt. You could have a water pump leaking and this would show coolant on the ground under the right front of the engine, more so when the engine is running. They are very common for all 3 problems.

Low coolant light is on with full radiator
Check the coolant top up reservoir. Low coolant sensor is usually in the overflow/reserve container.
Wash out and clean any dirt or corrosion from the sensor prong.
Refill to correct level with fresh coolant, then recheck alarm operation.
