Why does my BMW have 2 coolant tanks?

markers. BTW, the second smaller expansion tank is for your coolant-based charge air cooling. It’s essentially a separate coolant system with its own electric pump and expansion tank.

Where does the coolant go in a 2010 BMW X5?

Where is the coolant leak on a BMW X5?

  1. The engine runs hotter than normal, or overheats.
  2. You see a puddle of coolant under the car, or on parts under the hood.
  3. You notice the somewhat sweet smell of coolant in or around the car.
  4. The check engine light or temperature warning light comes on.

What is CAC in radiator?

Cooling the air with a heat exchanger as it leaves the compressor is a common way to achieve this charge air cooling. Such a heat exchanger is referred to as a charge air cooler (CAC), intercooler or aftercooler (Figure 1).

How do you drain the coolant on a 2013 BMW x5?

Can I put water instead of coolant in my BMW?

While you can drive the car for a short time using water in place of the coolant, it won’t effectively protect your engine. This means its essential to get the problem that caused a low coolant level fixed as soon as possible, and the radiator filled with a 50/50 ratio of coolant to water.

Why is my coolant level dropping but no leaks?

If the coolant level is dropping and there is no external leak evident, then the coolant is probably leaking internally, into the engine. If the car has recently overheated then this could have caused the head gasket to fail. If it has, it could be leaking coolant into the combustion chambers.

Can I put water instead of coolant?

Technically speaking yes you can use plain water in your cooling system but it isn’t recommended as a long term solution and certainly not in extreme weather conditions. The problem with using water in your cooling system is that water freezes at 0°C.

Is coolant the same as antifreeze?

Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it’s important to know what variety is right for your car or truck.

Why does my BMW say low coolant when it’s full?

If you check your coolant reservoir and it appears to be full, but your low coolant light is on, then your vehicle’s coolant sensor may be malfunctioning. Most automotive shops can diagnose a sensor malfunction and replace the sensor.

Can I drive with coolant level low?

If your car has a low coolant you can drive for some time. It really relies on the level of coolant. If it is low but it is above the minimum, you can drive your car for a few days. But if it is below the minimum, please do not even try to run your engine.

What causes BMW X5 coolant leak?

Most common in the BMW X5 is the valley pan—a staging area where coolant collects before being transferred to different parts of the engine block. The valley pan can corrode, and then it will leak coolant from a hole that just keeps getting bigger and bigger.

Why is my car leaking coolant from the driver side?

The leak that you are seeing could be from a coolant hose that is either loose or split. Also the coolant leak could be coming from a core plug (freeze plug). The best way to track a leak is to put coolant dye into the radiator, drive the vehicle for a couple of miles, and then pressure test the system.

Can I drive my BMW with a coolant leak?

Depending on how much coolant is lost, as long as it’s not dripping on the ground, you should be okay. Just make sure you monitor your engine temperature to make sure it isn’t overheating. If you feel think it getting too hot, shut if off right away.

How do you test a CAC?

You can also purchase a test kit with a gauge that attaches to the CAC and pressure it up to 30 psi. Your CAC should hold air for at least 15 seconds. If you lose 5 psi or more of pressure within 15 seconds, you may need to replace your CAC.

How do you know if your charge air cooler is bad?

  1. Leaking Coolant.
  2. Coolant Contamination.
  3. Over Heating.
  4. Check Temperature Guage.
  5. Inspect Coolant Leaks.
  6. Look for Air-pressure Leaks.
  7. Perform routine maintenance.
  8. Reduced Fuel Efficiency.

Are water to air intercoolers better?

The present study found that the air to water intercooler is more efficient and the heat transfer is much better than that of the air to air intercooler. This is due to the air flow to the water inside the intercooler is better compared to the system that uses an air to air intercooler system.

How much coolant does a BMW X5 hold?

Draining and filling your cooling system is a maintenance requirement as well as being part of many repairs. Engines used in BMW E53 automatic transmission models hold about 8.5 liters of coolant, manual transmission models hold 8.7 liters.

How often do you change coolant in BMW X5?

How often should you change coolant in a BMW X5? Typically, you should have your BMW X5 coolant flush completed every 30,000 miles or every two years. There are some instances where your vehicle can go without a flush for a longer period of time.

How do you flush a BMW cooling system?

With the entire cooling system drained, it’s time to do a quick flush using distilled water. With all the drain plugs back in place, fill the system with distilled water. Turn the car on and put the heater on max. Run the engine until it reaches the normal working temperature and opens the thermostat.

Do I fill the radiator or the reservoir?

If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water. When the coolant rises to the cold fill line, replace the cap and tighten it until you feel it click.

Does BMW use special coolant?

BMWs have specific coolant requirements (nitrite and phosphate free) to prevent build-up and corrosion of aluminum components, so not just any off-the-shelf antifreeze will do.

What color antifreeze does BMW use?

Genuine BMW green HT-12 antifreeze for optimal cooling system performance. Compatible with all BMW models.

Why is my car losing coolant but not overheating?

Chances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. The longer you wait the higher the coolant leak repair cost will be.
