Coolant Doesn't Seem To Circulate
Coolant Doesn't Seem To Circulate. Start up the engine and let it idle. Consequently, the coolant has not reached a high enough temperature to open the thermostat.

The cooling system is fully sealed, so the water pump doesn’t have to work too hard in order to circulate the coolant. A damaged reservoir tank can cause evaporation of the coolant; What can cause the engine coolant not to circulate, i'm sure there's a truck load of reasons.
You Have To Check Also For Your Alternator Drive Belt If They Are Broken.
The cooling system is fully sealed, so the water pump doesn’t have to work too hard in order to circulate the coolant. Try the heater, if it's hot you must have water circulation. Thermo is new.sensor is new, radiator is new.
Drive It And See If Coolant Stays In Normal Operating Range, Then You Know.
Your water pump is a major component in preventing your coolant from overheating. A damaged reservoir tank can cause evaporation of the coolant; What can cause the engine coolant not to circulate, i'm sure there's a truck load of reasons.
The Valve Being Open Will Not Circulate Coolant Unless The Pump Is Running.
As said, it's because the coolant in the engine block is below the lower radiator hose connection point; The hot coolant is pumped to the radiator by the water pump and is cooled by the radiator. You'll see the coolant in the reservoir start to get sucked down into the cooling system.
These Can Be External Or Internal Faults Causing Blockages.
The car has a 2.2 l engine. The low coolant light comes on when the temperature reaches around 205. Fill the reservoir with the engine off until coolant comes out the vent do this with the ignition on and engine not running with the heater set to max hot and the fan speed on the lowest setting.
Why Is My Coolant Overflow Not Draining Back Into The Radiator?
Now im not getting any hot air through the blowers and the coolant doesn't seem to be circulating. With the thermostat removed, the coolant should circulate continuously, making it harder for the engine to warm up. I have drained and bled the system 3 times as per the guides on here ie sliding the heater intake back to the bleed hole until water comes out etc.
