How many grams of refrigerant should be added to the Volkswagen Touran?
2 Answers
The refrigerant filling amount for the Volkswagen Touran is approximately 600-800g. Each vehicle model has a specified amount, which is indicated in the car's manual or can be controlled based on the pressure gauge reading. Below is a related introduction to refrigerant: Function of refrigerant: Refrigerant helps prevent the freezing of coolant during cold winter shutdowns, which could otherwise cause the radiator to crack or the engine block or cylinder head to freeze and crack. When adding refrigerant, first evacuate the system, then add Freon. The first canister can be added automatically, but for the second or third canister, you may need to start the car if it cannot be added. Precautions for adding refrigerant: The amount of refrigerant should be determined based on a professional air conditioning pressure gauge. Overfilling or underfilling refrigerant can lead to poor cooling performance or inadequate cooling effects.
When I previously replaced the refrigerant in my car, I specifically checked the manual. The R134a standard for the older generation Touran 1.6L is 550±25 grams, while the 1.4T model requires slightly more, around 750 grams. The key is to use a vacuum pump for at least half an hour before refilling to thoroughly remove any residual air and moisture from the system. The compressor oil also needs to be replenished, typically around 40 milliliters. Now, the EU has started banning R134a, so new models will have to switch to environmentally friendly refrigerants, and the refill quantities will need to be checked again. Always wear safety goggles during the operation—last time, my friend got splashed by the sprayed refrigerant mist and had eye pain for half a day.
