As the media documents each year, Britain can experience very dramatic changes in the weather. In the height of summer and winter, temperatures can fluctuate dramatically, causing potentially major problems under the bonnet of your car. The engine and components around it are prone to either overheating during the summer (think about the amount of energy generated in such a small, confined space mixed with a hot summer day) or freezing during the winter (there is virtually no insulation available to protect it from the cold).Comma?s range of coolants and antifreeze solves this problem as each formula is designed to protect your engine?s components throughout the year, allowing your engine to run smoothly. Containing Ethylene Glycol, Xstream G48 antifreeze and coolant concentrate is silicate based, giving protection from -36 degrees to +45 degrees Celsius. Suitable for both petrol and diesel engines, it protects against corrosion, erosion, overheating and freezing. Offers up to 3 years protection. Comes in a 1 litre bottle.Comma Oil and Chemicals was founded on a real ?passion for performance? in 1965 as a UK-based, independent oil 'blender'. Quickly establishing their products as being the first-choice supplier of engine oils to independent workshop mechanics in the UK, Comma has recently grown to distribute to more than 40 other countries around the world.Legal DisclaimerALL ORDERS PLACED BEFORE 11AM DURING THE WEEKDAYS WILL BE DISPATCHED NEXT DAY.
