Why Does My BMW Say Low Coolant
When It's Full in Walnut Creek?
For the smooth operation and functioning of the engine, the coolant is playing a vital role.
Coolant is used to cool down the engine when it will generate a lot of heat during the combustion process.
If the coolant level of the engine is lower, it will damage its internal components due to overheating.
Sometimes, you will find that your car shows low coolant even if the coolant tank is full.
The below points define the reasons behind your BMW says low coolant even if the coolant tank is full.
DAMAGED BLOCK OR GASKET
If the block or gasket of the car is damaged, then the coolant is leaking slowly from the engine.
As a result, it shows a low coolant level in the car when the coolant tank is full.
MALFUNCTIONED
SENSOR
If the coolant sensor of the car is failed, then it can show the wrong reading in the dashboard computer.
When it happens, you may notice numerous problems in a car while driving such as:
· Decreased fuel mileage
· Fail the emission test
· Shows low coolant when it is full
FAILED COOLANT PUMP
Sometimes, the failed coolant pump also indicates low coolant especially when several gaskets on the pump are worn out.
As a result, you will find a truckle of red or green fluid leaks under the front area of the car.
BAD THERMOSTAT
Apart from the sensor, the bad thermostat also causes low coolant issues in the car.
When the thermostat gets stuck open, the engine says low coolant level even if the tank is filled with sufficient coolant.
AIR IN THE SYSTEM
During routine service and maintenance, the air packets are accumulated within the cooling system.
When it happens, you will notice that the coolant level appears greater than the actual level, but says low coolant in the engine.
C O N C L U S I O N
Whenever you will found that your BMW says low coolant when it is full, bring it to a mechanic immediately.
Left it untreated for longer can cause major damage to the engine and other related parts.
