كم مرة يجب تغيير سائل غسيل الزجاج الأمامي؟

You should check and refill your windshield washer fluid much more often than you think in the UAE, not based on a fixed monthly schedule. During the hot summer months, I find myself topping up the fluid in my Nissan Patrol every 2-3 weeks due to rapid evaporation and frequent use on dusty Sheikh Zayed Road. The crucial point is to change the type of fluid seasonally. For most of the year, a standard fluid is fine, but before the brief, cooler winter months—especially if traveling to Jebel Jais where temperatures can drop—you must switch to a winter-grade formula with a freezing point at least 10°C below the expected low. Using summer fluid in winter risks it freezing, damaging the pump. RTA Dubai's vehicle maintenance guides emphasize regular checks of all fluid levels, while practical advice from workshops aligned with MOI UAE's safety standards highlights the seasonal switch as a key preventative measure for GCC-spec vehicles.

Season (UAE)	Fluid Type	Key Reason	Check Frequency
Summer (Apr-Oct)	Standard Concentrate	High evaporation, dust, insects	Every 2-3 weeks / refill as needed
Winter (Nov-Mar)	Antifreeze Formula	Prevent freezing in sub-20°C areas	Refill with winter fluid in October

• Typical Cost: A good quality 2L concentrate costs ~15-20 AED, diluting to ~4L of usable fluid.
• Summer Consumption: My Toyota Hilux uses about 1 liter per month commuting on Dubai-Abu Dhabi highway.
• Pump Replacement Cost: If the fluid freezes and the pump fails, the repair at a Dubai workshop can cost 200-400 AED including parts and labor. The annual cost is negligible, but skipping the winter change can lead to a costly repair. Just keep a spare 1L bottle in the boot and refill when the level is low; it's simpler than marking a calendar.

As a used-car showroom manager in Sharjah, the first thing I check during a pre-purchase inspection is the washer fluid. If it's empty or filled with plain water, it's a red flag. It tells me the previous owner likely neglected other, more expensive maintenance. Water leaves mineral deposits that clog the nozzles, and in our heat, algae can grow. I always advise buyers to immediately do a full flush and refill with proper concentrate after purchase—it's a 30 AED investment that protects a 300+ AED pump system.

Most people just top it up, but they should flush the system once a year. In the UAE's heat and humidity, a mix of tap water and cheap fluid leaves a sticky residue and scale inside the tank and pipes. I've seen it block the small filter in the pump. For my customers' cars, like the popular Hyundai Tucson and Kia Sportage, I recommend a full drain and clean before the summer starts. Use distilled water with the concentrate to avoid new scale buildup. It takes 10 extra minutes but doubles the pump's life.

From an insurance perspective, maintaining clear visibility is a policyholder's duty. If you're in an accident and your washer reservoir was empty, leading to a dirty windshield at a critical moment, it could be noted as contributory negligence. This might affect your claim. Simply keeping the fluid topped up is a basic, documented step in responsible vehicle upkeep that supports your position. It's a minor habit with major implications for liability.
