Approximately 750g. Here is some relevant information about the Peugeot 307: 1. Powertrain: The Peugeot 307 is equipped with a 1.6L naturally aspirated engine, delivering a maximum horsepower of 117 hp, maximum power of 86 kW, and maximum torque of 150 N·m. 2. Fuel consumption: According to the official combined fuel consumption data, the Peugeot 307 has a combined fuel consumption of 7.3L/100km. 3. Transmission: The Peugeot 307 offers a choice between a 5-speed manual transmission and a 4-speed automatic transmission with manual mode. In terms of suspension, the front suspension of the Peugeot 307 is a MacPherson strut independent suspension, while the rear suspension features a deformable crossbeam with a stabilizer bar.

Having driven the Peugeot 307 for so many years, I've had the air conditioning repaired quite a few times. The original manual clearly states the refrigerant amount should be between 550-650 grams, depending on the year and compressor model. For the earlier 1.6 versions, about 560 grams of R134a refrigerant is needed, while the 2.0 models require around 650 grams. However, I must emphasize two critical points: First, you must use an electronic scale for precise measurement—guessing the amount at a roadside shop will likely cause problems. Second, you must evacuate the system for at least half an hour before refilling. Otherwise, moisture in the AC lines will mix in, drastically reducing cooling efficiency in the summer. Last time I skipped the vacuum to save money, and the expansion valve froze and clogged, costing me over 800 yuan to fix.

Having repaired over a dozen 307 air conditioning systems, I've found the refrigerant quantity isn't fixed. For pre-2004 models using R134a refrigerant, the recommended charge is 650±20 grams. For post-2010 facelifted versions with optimized compressor structures, 550 grams usually suffices. In practice, I prefer a two-stage charging process: first inject 80% of the specified amount, run the AC compressor for ten minutes while monitoring high/low pressure gauge readings, then top up the remainder based on pressure differentials. Important note: If old refrigerant isn't fully purged before new charge, cooling efficiency drops by over 30% and pipeline corrosion risks increase significantly.

As an environmental inspection station technician, I've noticed many car owners improperly adding refrigerant. The Peugeot 307 specification requires R134a environmentally friendly refrigerant, with the total amount strictly controlled between 550-650 grams. Overfilling not only reduces cooling efficiency but also causes abnormal compressor noise due to excessive load. The key lies in the vacuuming process – less than 25 minutes of vacuuming is ineffective, and system moisture residue exceeding 500PPM may lead to intermittent cooling all summer. In our last inspection, 80% of vehicles exceeding standards had either refrigerant exceeding 700 grams or were using inferior quality refrigerant mixtures.

Last month, I just had the air conditioning issue of my 307 addressed at the 4S dealership. The refrigerant charge varies by model: 650 grams for the TU5JP4 engine, while 600 grams is sufficient for the EW10J4 engine. The workflow chart posted in the service bay specifies: evacuate for 30 minutes followed by a 15-minute pressure hold test. If the gauge pressure fluctuates by more than 0.05MPa, a leak check must be repeated. Two critical points during refilling: the refrigerant can must be inverted to charge liquid refrigerant, and at an ambient temperature of 25°C, the low-side pressure should read between 250-320kPa. I once saw an apprentice charging gaseous refrigerant with an upright can—ended up using three cans without achieving any cooling effect.
