How Much Refrigerant Should Be Added to the X-Trail?

The refrigerant filling amount is indicated on the label, with a standard of 450 grams plus or minus 50 grams. Currently, one bottle of refrigerant on the market is approximately 220 grams, so two bottles should be sufficient. High-pressure side refrigerant filling: Suitable for filling after leak detection and vacuuming. Note that this method must not involve starting the compressor, and the engine should be off. Additionally, the refrigerant can must be inverted during the process. Low-pressure side refrigerant filling: This method involves filling gas, characterized by a slower filling speed and is typically used for refrigerant replenishment. If bubbles continuously appear in the sight glass of the car's air conditioning pipes during normal operation, it indicates insufficient Freon, which requires topping up.
This issue is actually quite common. Regarding how much refrigerant the X-Trail's air conditioning system requires, it mainly depends on the specific model year and engine displacement. For example, models from 2014 to 2020 typically use refrigerants like R134a, with the quantity usually around 600 to 700 grams. From my car enthusiast experience, randomly adding refrigerant can lead to reduced AC performance or even compressor damage, so it's best to check the air conditioning section of the vehicle manual or the label under the hood for the exact amount. If the refrigerant is insufficient, you'll notice weak cooling performance and strange odors upon startup – in this case, you should first check for leaks before replenishing. Overfilling can cause dangerously high pressure that may lead to pipe bursts. Personally, I don't recommend DIY handling as refrigerant is high-pressure gas requiring professional tools and safety equipment. I always go to a reliable repair shop to get it done while having them check pipeline seals to ensure no issues during long trips.
My old X-Trail has been running for almost ten years, and I've learned to be cautious about refilling the AC refrigerant. The standard amount is around 600 grams of R134a, but it's best to check the manual or label for specifics. Once, I didn't refill it properly, and during summer, the car became unbearably hot—turns out it had all leaked out. Now, experience tells me: when cooling performance drops, first check the system pressure or look for leaks before rushing to add more. Adding too much or too little affects the system's lifespan and increases fuel consumption. It's best to let the shop technicians use an electronic scale for precise refills during regular maintenance—it's both hassle-free and safe. By the way, older cars might use different refrigerant types, requiring a system change, while newer models might need R1234yf, which is more expensive but environmentally friendly. In short, don't risk DIY to save a few bucks; spending a little at the repair shop is the right way to go.
