The expense of repairing a coolant leak will increase the longer you wait. Discover the cause of your antifreeze leak and what to do next.

BMW coolant is what color?

To maintain your cooling system operating at its peak, we advise using only German OEM BMW engine antifreeze, part number 83192468442. (83 19 2 468 442). Because they don’t include nitrites, amines, phosphates, or borates, BMW exclusively suggests specific coolants. It is not permitted to use store-bought coolant from a nearby parts retailer.

2018 saw the introduction of this new green coolant, which has replaced the previous blue coolant. Green can be used on automobiles before 2018 and is backwards compatible with blue. BMW advises against using the older blue formula on vehicles created after January 2018.

The silicates in the green coolant provide further protection for the cooling system’s internals, although the coolant needs to be changed every two years.

For increased corrosion resistance, anti-freeze defense, and water pump lubrication in street cars, we advise combining distilled water in a 1:1 ratio with the mixture. Reduce the amount of antifreeze in your coolant mixture if you want more cooling properties, but only in warmer climates where freezing is impossible (see chart below). We advise monitoring the freezing point of the coolant mixture if you want to use antifreeze and water ratios other than 1:1.

Red Line Water Wetter can also be added if high temperatures could lead to engine banging or pre-ignition.

  • Original BMW HT12 antifreeze from Germany, part number 83192468442
  • optimum cooling, freeze prevention, lubrication of the water pump, and corrosion resistance

What causes my auto to use so much coolant?

Several variables can lead to antifreeze leaks, but the two most frequent ones are aging and unclean coolant. Coolant that contains dirt or oil can hasten system wear and cause leaks at gaskets, o-rings, and water pumps. The best method for stopping this type of leak is to flush your cooling system.

The aging process is also hard on the hoses and plastic parts of the cooling system, which are the most frequent sources of antifreeze leaks. In this situation, a leak cannot be stopped. Nevertheless, it is crucial to keep an eye out for any cooling system component that can be damaged.

Why must I constantly add coolant to my car?

Your car’s coolant is a crucial fluid. Without it, parts will overheat and ruin your engine, necessitating costly repairs. There is a good probability you have a coolant leak if you see fluid on the ground where you park or need to regularly add more coolant to the engine.

  • the cooling system becoming overfilled
  • defective radiator cap
  • a deteriorated radiator hose
  • a leak that only happens under specific operational circumstances
  • a blown gasket, an unidentified damaged cylinder head or engine block, or
  • towing large objects

Whatever the cause, you must take care of the issue before it necessitates a more involved and costly repair. If a minor leak suddenly grows larger and the engine overheats without having enough time to cool, coolant loss could cause your engine to fail.

The most frequent causes of coolant loss are discussed in the following sections, along with several tests you can perform in your own garage.

The first few sections provide you some basic diagnostic tests and items to examine depending on your specific situation before you enter full troubleshooting mode. Later tests for troubleshooting become more complex.
