When dealing with coolant leaks it is important to understand what that means for your vehicle’s performance, and why it happened to begin with. Dealing with this issue rather quickly is important to the proper function of your vehicle. If not properly addressed, coolant leaks can result in problems for your car. There are signs you may begin to notice if you are dealing with a coolant leak. If you are unsure, it might be wise to consider visiting a trusted mechanicpreferably one who is familiar with working on BMWs.

Causes of a Coolant Leak

Like most problems, there are usually signs that may indicate you are dealing with an issue. In the case of a coolant leak, one possible cause could be that the reservoir is made from plastic and may begin to wear over time. If it wears too much, it could crack and cause a coolant leak in your vehicle.

The coolant in your car is what helps maintain and control the temperature of your engine. You want to note that you neither want your engine too hot, or too cold. If your car is leaking coolant, your engine may lose its ability to regulate its temperature, putting sensitive engine components in danger.

If you suspect that your coolant reservoir is leaking, you will want to have the entire cooling system inspected. If the reservoir has worn out, there is a strong chance that other components in the cooling system have worn out as well. If other parts have worn out, then you may have additional leaks that you will want to get diagnosed and repaired. As previously mentioned, it is important to make sure your vehicle is not overheating, as this can cause serious damages to your car. These damages can be incredibly costly, but they can be avoided if you are properly maintaining your vehicle.

There are several tests that can be done in order to determine if your car is in fact experiencing a coolant tank leak. The best, and most effective way to determine if you are having a problem with your engine’s cooling system is to test the pressure. A pressure tester is a handy tool to have that can help when dealing with the cooling system in your car. Since there are different ways the coolant could be leaking (internal leak or external leak), it is a good idea to use a pressure tester to determine if there is a leak.
