How to Troubleshoot Cooling System problems in BMW X3?

All we know that the BMW X3 engines is running hot due to the burning of more fuel for powering up the car. To prevent the engine from overheating and other major damages, the cooling system is performing the proper mixture of water and coolant in the radiator and circulates them through the water pump in the engine.

Due to these reasons, make sure that the cooling system is running efficiently. Otherwise, it may lead to severe engine damages. In general, the cooling system problems are lying in 3 common areas such as overheating, over cooling, and unusual noises. The following points define the common problems of the cooling system and the way to troubleshoot them.

Overcooling of engine

In general, engine overcooling issues are arising in your BMW X3 in winter because the heater is unable to function properly. On the other hand, the engine is overcooled when it is running below its normal operating temperature.

Moreover, it is caused when the thermostat remains open all times or the coolant bypass valve remains open. When it happens, you have to test the thermostat and replace it immediately. Thus, the overcooled engine can cause numerous issues in your BMW like:

Worn the cylinder

Lower down the thermal efficiency

Engine unable to get its desired power

Increase the loss of fluid friction

Oil unable to thin out properly

Coolant frozen

When the BMW X3 is parked below the freezing temperature, its water is freezing in the cooling system. As a result, the cooling system is breaking down entirely and cause serious damages to different parts of the system. Before operating the BMW, it’s always better to check the cooling system for determining the damages arising due to the frozen coolant.

If the coolant in the cooling system is frozen, then the engine is reaching idle speed. Throughout the operation, the coolant is reduced due to the formation of the steam and replenished to keep the system from using it another way. Don’t drive the car, until all the coolant is circulated into the system.

Leakage of coolant

The coolant is generally leaking from the cooling system due to numerous reasons. When the coolant is leaking internally, then it drains into the engine oil and causes a loose cylinder head, breaks the engine block, and damages the head gasket in your BMW X3.

Through proper inspection, the coolant leaks can be easily determined in the cooling system. If the coolant leak is increased, then it will increase the oil level lubrication in the oil pan. Due to these reasons, you have to check the coolant level of the BMW and replace it as necessary.

Wrong reading of temperature gauge

To give the wrong reading of the temperature gauge, the temperature indicator or gauge is fitted on the instrument panel. If it is damaged, then the temperature gauge is either needs replacement or immediate repair.

Moreover, performing the frequent check of the temperature gauge with a thermometer is the best way to determine the temperature of the cooling water in the radiator tank. Throughout the process, you can easily compare the readings of the gauge in the BMW X3.

Engine overheating

The main problem with the cooling system is the engine overheating in the BMW X3. Moreover, it is arising in your car due to insufficient quantity of water in the cooling system and maybe resulted in coolant loss. On the other hand, the engine overheating is also arising in your BMW without any coolant loss.

Apart from the coolant loss, the engine overheating is also arising in your BMW due to other reasons. It’s always advisable to consult with a reputed mechanic for fixing the coolant loss problems in your BMW as soon as possible.

Final thoughts

Among the several problems of the cooling system, the noise is also produced in a long run. When you notice any type of problem in the cooling system, then it will illuminate the check engine light on the dashboard. Without any delay, you have to bring your BMW X3 to a reputed and certified mechanic for fixing the issues. In this way, the cooling system problems are troubleshooting and fix it efficiently.
