10 Common BMW X3 Engine Overheating Causes in Thousand Oaks

10 Common BMW X3 Engine Overheating Causes in Thousand Oaks The engine overheating is a common problem that can be faced by the driver and owner of all cars. Thus, the engine of your BMW X3 is overheated, when the cooling system is under constant pressure and high temperature. If you are driving the car with an overheated engine for a prolonged period of time, then it may lead to major engine damages.

When the engine overheated problem is started, you just need to pull the BMW to the side of the road and do the repair yourself. Give proper attention and prevention of the engine overheating issues will save your engine and money. The below points will define the common causes behind the engine overheating issues of BMW X3.

Damaged thermostat The thermostat is an important component of the BMW which is located in the coolant system to allow the flow of coolant. When the engine reached its working temperature, the thermostat starts opening and lets the coolant to flow freely through the entire system. If the engine is in cold condition, then the thermostat can lead to a closed position and heats up the engine more rapidly.

If the thermostat is stuck in the open position, then it unable to reach its working temperature and keep the engine stays cold. Apparently, if it is stuck in the closed position, then it may lead to engine overheating issues due to the lack of proper coolant flow.

Broken cabin heater The cabin heater is working the same as the engine radiator that is used for heating the passenger cabin. Thus, the cabin heater is rarely broken because it is located inside the passenger cabin. When the hot coolant goes through the heater, the cabin ventilator is blowing air through it and heat up the cabin.

Over time, the cabin heater is starting to leak or clogged up due to material fatigue. Before the engine is overheating, you will experience the problem when the coolant is leaking into the passenger cabin. For preventing the issues, you need to replace the cabin heater.

Failed water pump The water pump is an engine-driven turbine in the BMW that can keep the coolant flow through the engine. So, when you start the car, the water pump is pushing the coolant through the engine immediately.

In modern cars like BMW, the water pump is driven by the camshaft timing belt and mounted on the outer side of the engine. When the impeller fins are broken, the water pump is failed in your car and causes major engine damages. So, find a good BMW mechanic to replace the timing belt on time to avoid the problem.

Fluctuated engine coolant When the coolant level is placed between the middle marks, you will notice normal system pressure. The fluctuated engine coolant is the most common reason behind the engine overheating and that would be caused due to invisible leaks, the loose cap on the coolant reservoir, and evaporated low-quality coolant.

On the other hand, too much coolant also produces additional pressure in the system and lead to engine overheating. So, perform the regular checkup of the coolant system and add the necessary coolant when it is needed.

Clogged coolant system The coolant system is highly beneficial for your BMW X3 for the proper flow of the coolant throughout the system. In the engine block, the coolant is going through the radiator, hoses, and canals which may be clogged over time. When you are using the tap water instead of the coolant, it may be clogged the coolant system entirely.

Subsequently, using the low-quality coolant can also cause problems in the cooling system that may lead to engine overheating issues. So, to prevent the clogged cooling system or engine overheating, you have to replace the old coolant and flush the engine completely.

Sloppy hose clamps The most common causes behind the engine overheating issues in your BMW are the sloppy hose clamps. Over time, the clamp can be loosening up, shrunk, or break due to high pressure.

Due to the loose clamp, the hose is leaking and may lead to engine overheating issues.

To prevent the sloppy hose clamp issues of the BMW, you have to purchase the same coolant hose and diameter clamp and replace it properly. If it is accessible, then does it on your own, otherwise, consult with a mechanic for doing it?

Failed head gasket The head gasket is working as a seal between the cylinder head and engine block and without the proper functioning head gasket and then the engine cannot be function properly. When the head gasket is failed, the oil and coolant can be mixed and constantly overheating the engine.

Due to these reasons, when you open the coolant reservoir, you will notice foam like substances inside the gasket. All of the issues indicate that the head gasket is failed and needs immediate replacement. Neglecting the issues for a long may lead to expensive repairs in your BMW.

Malfunctioned thermal switch The thermal switch is an electrical switch of the car that can be located on the radiator and functioned with the coolant temperature. When the coolant temperature is increased, the switch can activate the radiator fan.

If the thermal switch is malfunctioned due to any reason, then it is unable to activate the fan. As a result, the coolant temperature is increased and leads to engine overheating. So, to prevent the issues, you have to replace the thermal switch by consulting with a reputed mechanic.

Leaks in the coolant hose The common causes behind the engine overheating in most of the cars are the coolant hose leaks. However, the coolant hose is leaking when it is brittle and loose due to the variations of the harsh environment and temperature.

Eventually, it may lead to engine overheating issues in your BMW. You can prevent it through time to time inspection, if it has minor cracks, then you should replace it as soon as possible by own depending on the hose accessibility.

Broken radiator The main purpose of the radiator is to lower down the engine coolant temperature. When you are driving the car, the coolant is flowing through the radiator. Over time, all the components of the radiator are clogged up or broken. If it is broken, the radiator is leaking and cause engine overheating issues.

You can prevent the broken radiator issues of your BMW X3 either by cleaning or replacing the radiator. The cleaning can be performed by flushing the inside of the radiator and replace it with a certified BMW mechanic.

Conclusion If you are facing engine overheating issues in your BMW X3 due to unusual environmental conditions in Thousand Oaks, then consult with a reputed mechanic for fixing the issues as early as possible.
