Ireland can experience very dramatic changes in the weather all year round. 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).The Prestone range of antifreeze/coolants is compatible with all vehicle makes and models offering extreme protection against all temperatures all year round. The patented corrosion inhibition system, using Organic Acid Technology (OAT) protects the cooling system from corrosion for up to five years or 150,000 miles. Formulation meets or exceeds recognised national and international coolant standards also meets or exceeds OEM performance requirements.
