In the UAE, you should replace the coolant in your Peugeot 408's GCC-spec model every 2 years or 60,000 km, whichever comes first, due to extreme summer heat. The 40°C+ temperatures and constant A/C load degrade coolant faster to prevent overheating and corrosion. For the common 1.6L turbo engine here, you need to use a specific, phosphate-free OAT (Organic Acid Technology) coolant that meets the PSA B71 5112 standard, not just any off-the-shelf product. Using an incorrect type can damage the radiator and heater core. The total cost for a professional coolant change at a reputable garage in Dubai typically ranges between AED 400 to AED 700, parts and labor included, which is a small price to prevent major engine damage costing thousands. If you drive 25,000 km a year, this service cost adds less than 1.5 fils per km to your running costs, a key part of your vehicle's TCO. The RTA Dubai's vehicle maintenance guides emphasize regular cooling system checks as critical for roadworthiness, especially before summer. The UAE Ministry of Industry and Advanced Technology (MoIAT) and the Gulf Standardization Organization (GSO) have standards for automotive fluids to ensure they perform under local conditions, making it essential to use approved products.
