Frequently asked questions

  • What happens in cooling systems?

    On average, around ca. 150 liters of coolant are pumped around the cooling system of a car engine each minute, and commercial vehicles have a much larger cooling system. The mixture of water and coolant can come into contact with up to a hundred different materials. Unless the correct engine coolant is selected, the high temperatures and high pressure drop in the system create ideal conditions for rust and cavitation. Without any protection, the cooling water can etch deep holes into the metal and damage the cylinder head, cylinder liners and water pump. This can cause the cooling system to fail and can even damage the engine beyond repair.

    Motor manufacturers have very specific demands on the performance of engine coolants, depending on which materials they come into contact with. Glysantin® has been working in close cooperation with all leading motor manufacturers for many decades and has developed a suitable product for every engine.

  • How does Burke Coolants work?

    Burke Coolants increases the boiling point of the cooling water to around 110℃. Mixtures of water and Burke Coolants can absorb more heat than pure water without boiling. Burke Coolants is also very effective for preventing scale formation in cooling systems. Scale quickly tends to block the narrow channels in the system and prevents heat from being transferred to the ambient air. This can easily lead to overheating in the summer months. Burke Coolants also performs very effectively as an antifreeze.

  • Why are coolants coloured?

    The colour of the coolant is defined in the specification from the vehicle manufacturers and is also a small but important part of the official approval from the vehicle manufacturers.

    Important note: By the colour alone, it is not possible to identify the engine coolant. The colour of the engine coolant does not define the chemical and technical properties.

  • Why do coolants have to be changed?

    Coolants have to be changed every three to four years depending on the product. This is important, because the additives contained in coolants are gradually broken down. Coolants retain their antifreeze action for a long time, but the corrosion inhibitors break down over time and no longer protect the cooling system from damage.

  • Should coolants be poured into the drains?

    No. Coolants are chemical substances and they often become contaminated after years of service in the cooling system. Pouring them into the drains is an offence against waste disposal legislation and is punishable by law.

  • Should coolants be used undiluted?

    No. Coolants always have to be diluted as undiluted products do not have sufficient capacity to absorb the heat from the engine, which leads to overheating. Undiluted coolants can also freeze in winter. For this reason Burke Coolants is available in both Concentrate form (for customers who wish to dilute the product themselves) and Ready to Use formulas.

  • In what proportion should Burke Coolants Concentrate products be diluted
    with water?

    When you are changing the coolant, we would always recommend that you dilute Burke Coolants Concentrate products with water at a ratio of 50:50 in order to obtain the best possible protection from corrosion, overheating and frost. The concentration of Burke Coolants Concentrate should be no less than 33 % and no more than 60 %.

  • Can normal tap water be used to dilute Burke Coolants Concentrate?

    Normal tap water can mostly be used to dilute coolants if not harder than 3.5 mmol/l or contains chlorine etc. We recommend using demineralized or distilled water.

  • Can Burke Coolants be purchased as a pre-mixed 'Ready to Use' product?

    Yes, we have found that there is a customer requirement for pre-mixed - 'Ready to Use' antifreeze/coolant in additon to the Concentrate product. Therefore Burke Coolants is available to purchase in both Concentrate and Ready to Use formulations. This enables each customer to make their own decision on whether they wish to dilute the product themselves or purchased in a 50/50 pre diluted mix offering frost protection to -38 (degree C sign)

  • What are the implications of approval by motor manufacturers?

    Motor manufacturers only grant approval to products and do not issue recommendations. If a coolant has been approved by the motor manufacturer for original use, it may be changed during the period covered by the guarantee without affecting the manufacturer's warranty.

  • How long can Burke Coolants products be stored?

    Burke Coolants products have a shelf life of at least three years from the date of manufacture in their sealed original packaging. Its service life after it has been diluted with water depends on the vehicle manufacturer's specifications. We generally recommend changing coolants every 3-4 years.

  • Is Burke Coolants harmful to health?

    Burke Coolants contains ethylene glycol (ethanediol), which is harmful if swallowed. Contact with the skin and eyes must be avoided. Burke Coolants must be kept out of the reach of children and pets. If you do swallow Burke Coolants, you should seek medical attention immediately and show the doctor the packaging or label. You can also obtain qualified assistance by calling the emergency telephone number that appears on the Burke Coolants packaging.

  • Can I mix different Burke Coolants products with each other?

    Burke Coolants products can be mixed with each other, but we do not recommend this. Each product contains a different combination of additives that are compatible with the different materials in the cooling system. Mixing different additives can impair their overall performance and reduce the level of protection.

  • Can Burke Coolants products be mixed with coolants from other manufacturers?

    We do not recommend mixing Burke Coolants products with other coolants. The formulations of different products vary widely, and mixing them can lead to severe compatibility problems.

  • Can Burke Coolants be used in other non-automotive applications?

    We do not recommend using Burke Coolants products for any purposes other than those for which they are intended. Burke Coolants products are developed and tested for use in automotive cooling systems. We do not usually have any information on using Burke Coolants in other applications.
