The coolants used in passenger vehicles need to be changed every three to four years, depending on the type of product. This is important, because the additives contained in the coolant gradually break down. Burke Coolants still prevent the cooling water from freezing, but it can no longer be fully ensured that the customized additives will still be able to protect the cooling system from corrosion.

It is important to completely drain all of the old cooling water. The best results are obtained if the cooling system is flushed with water before the new coolant is poured in. Please note that cooling water may not be discharged into the drains. It is important to ensure that the coolant is approved by the manufacturer of the vehicle.

Burke Coolants Concentrate antifreeze/coolant is best diluted with demineralized or distilled water. Also tap water can mostly be used if it is not harder than 3.5 mmol/l. If your water quality is unclear or your tap water very hard we recommend to always use demineralized or distilled water.

When changing coolant, we recommend diluting Burke Coolants Concentrate 50:50 with water and we would recommend using standard Burke Coolants products to ensure optimum protection from corrosion, overheating and frost.

Make sure that you dilute the coolant correctly: the concentration of Burke Coolants should not be less than 33% and not more than 60%.

It is important to make a distinction between coolants that contain silicates and those that are free of silicates. Different types of products should never be mixed with each other, because this impairs the effectiveness of the additive packages. In the worst case, lasting damage can be done to the engine.

Mixing different engine coolants or using the wrong coolant can impair the performance of the special additive packages, and this can result in increased corrosion to the radiator. The passive layer in the cooling system gradually becomes thinner and more porous and the engine coolant needs to be changed at more frequent intervals. Using the wrong engine coolants can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket. This can lead to engine failure in the worst case.

Engine coolant additives such as the pH buffer are gradually broken down and become less effective with age. We therefore recommend a complete change of coolant every three to four years. It is also strongly recommended to clean the cooling system and completely renew the coolant whenever a repair is made to the cooling system. This prevents the rust, soil and suspended particles left behind in the system from causing scale, corrosion and other damage.

Burke Coolants can be purchased as Concentrate or pre mixed 'Ready to use' products.
