BMW 530i Radiator

Signs That There is Something Wrong with Your BMW 530i Radiator

The radiator in your car helps in maintaining a cool temperature under the hood. When the radiator fails, your vehicle will have a difficult time cooling down and that could lead to engine overheating. It's not uncommon for radiators to break down, and the BMW 530i radiator is no exception. Below are some signs that indicate failure in your car's cooling system:

Coolant leak

If you notice a trace of coolant seeping out from the underside of your vehicle, you need to check your radiator reserve tank for cracks or holes. Sometimes, the leak can be very bad that the amount of coolant inside the overflow reservoir becomes nearly used up. When this happens, you need to seal off the openings where the leaks are coming from. Doing so will help you save on coolant and make your radiator function efficiently.

Oil contamination

When radiator coolant from the overflow reservoir mixes with engine oil, you can be sure that there is an internal gasket problem in your vehicle. Engine oil should never mix with the coolant at all costs. If it does, the oil will no longer be efficient in lubricating the engine, and that can lead to engine failure. You cannot use your vehicle until the problem is fixed, so it's best to close all holes that might lead to coolant leak.

Radiator fan breakdown

Your car's cooling system is made up of different components that help dissipate heat from the engine. If one of the parts break down, your radiator becomes less efficient in cooling the engine block and that could lead to overheating. Sometimes, the radiator fan malfunctions, so air is not properly directed to the engine. This decreases your radiator's capacity of cooling your vehicle. The cooling fan should turn on automatically once the vehicle remains at idle. If it doesn't, then there must be something wrong with the fan (perhaps with the blades or with the fan shroud).

Worn-out hose

The coolant in the radiator circulates through hoses connected to the engine. These hoses can crack or split when the clamps that hold the ends of the hose together are over-tightened. If the hoses have cracks, the coolant directed toward the engine could leak. You'll need to replace the hoses with new and sealed ones to prevent the coolant from escaping.

  • How to Keep Your BMW 530i Radiator in Top Condition 27 February 2013

    When your car is working overtime, it needs all the help it can get to keep cool, especially during hot days. The BMW 530i radiator is efficient in frittering away heat that has accumulated in the engine block. Since you'll be using your radiator every time you drive, you need to make sure that it's always in top condition. Here are some ways to keep your radiator from premature breakdown:


    Prevent coolant leak by sealing in cracks.

    Repair small cracks on your radiator before they even become a complete nuisance. Coolant in the overflow reservoir can escape through small holes in your cooling system. When that happens, your radiator will not have enough to dissipate the heat from the engine. The coolant can also mix in with engine oil, rendering your vehicle useless until the next oil change. If the cracks can no longer be sealed, it might be best to get a new overflow reservoir or new hoses to prevent the coolant from seeping out.


    Flush out radiator fluid regularly.

    Although radiator fluid can last years when stored properly, it shouldn't be left inside your car's radiator for very long. You need to drain the fluid in your radiator to prevent clogging up your car's cooling system. The process for flushing is very straightforward-all you need to do is make sure that is completely cleaned off of old fluid before pouring in fresh one. Check the reservoir after every 30,000 miles to see if there is a need to replace the fluid. You'll need to get one of those test strips to check the alkalinity of the coolant and to determine whether you need to have the coolant flushed out.


    Make sure that the radiator fan is working properly.

    The radiator fan may not be the central component in a cooling system, but it helps in dissipating heat from the engine by blowing off cool air. When the cooling fan fails to operate, no air will flow to the engine. This decreases your radiator's cooling power, and you need to fix the problem immediately. Sometimes, all a radiator fan needs is a little cleaning. You can use s small brush to remove the buildup of dirt on the fan blades. However, missing components like the fan shroud can hamper the efficiency of the fan. Install one right away to keep your radiator functioning properly.
