Freon filling volume in Nissan Terrano: data for all generations (2005–2023)

Air conditioning in Nissan Terrano is one of those systems that requires regular maintenance, but is often left unattended until it stops working. The main problem that owners face is leakage or improper refilling of freon. Without exact data about filling volume the risk of damaging the compressor or other system elements increases significantly.

In this article we have collected relevant information on all generations Terrano (including R51, J10 And L50), indicated the types of refrigerants, provided step-by-step instructions and listed critical errors, which are allowed when refueling. If you plan to service the air conditioner yourself or just want to monitor the work of the service station, you will find everything you need here.

Freon filling volume by Nissan Terrano generation

The amount of refrigerant depends on car modifications, year of manufacture and type of air conditioning system installed. Below is a table with exact data for all versions Terrano, including rare configurations.

Generation/Model	Years of manufacture	Refrigerant type	Filling volume (g)	Notes
Nissan Terrano R51 (D40)	2005–2015	R134a	500–550	For versions with manual climate control
Nissan Terrano R51 (D40, automatic climate)	2005–2015	R134a	600–650	Electronically controlled systems require more volume
Nissan Terrano J10 (Renault Duster)	2014–2020	R134a	450–500	The volume depends on the presence of rear air conditioning
Nissan Terrano L50 (for Asian markets)	2020–2023	R1234yf	400–450	New environmentally friendly systems with reduced volume

⚠️ Attention: If your Terrano equipped with a system with rear air conditioning, to the specified values you must add 100–150 grams Freon. This rule applies to all generations, including restyled versions.

Also keep in mind that after air conditioner repair (replacement of the compressor, condenser or tubes) volume adjustment may be required. In such cases it is recommended to use diagnostic equipment for accurate calculation.

Which freon is suitable for Nissan Terrano: R134a or R1234yf?

The choice of refrigerant depends on year of manufacture and the region for which the car was produced. Until 2020 the majority Terrano refueled R134a, but with tightening environmental standards, the manufacturer began the transition to R1234yf.

The main differences between refrigerants:

• 🔹 R134a - classic freon, cheap and widespread, but with a high global warming potential (GWP = 1430).
• 🔹 R1234yf - a modern refrigerant with a low GWP (4), but expensive and requiring special equipment for charging.
• 🔹 Replacing R134a with R1234yf without modification of the system is impossible - it requires replacing the oil, seals and sometimes the compressor.

⚠️ Attention: If your Terrano 2015–2019 model year, but intended for the European market, there is a high probability that it is already used R1234yf. Check the sticker under the hood or in the service book - it indicates the type of refrigerant.

What happens if you mix R134a and R1234yf?

Mixing these refrigerants results in a chemical reaction that creates acids that attack seals and metal parts of the system. The compressor can fail within a few months, and repairs will cost 3-5 times more than proper refilling.

If you are not sure about the type of freon, never fill the system at random. It is better to contact a service station with equipment for refrigerant analysis or use test kit to determine the type of freon.

Step-by-step instructions for refilling the air conditioner in a Nissan Terrano

Refilling freon yourself is possible, but requires preparation and compliance with safety precautions. Below is a universal instruction suitable for most versions Terrano.

🔧 Check the tightness of the system (for leaks)

🔧 Buy freon of the required type (see table above)

🔧 Prepare the pressure manifold and hoses

🔧 Wear safety glasses and gloves (freon freezes the skin)

🔧 Make sure the engine is warmed up to operating temperature -->

Refilling process:

1. Connect pressure gauges to service ports (low and high pressure). B Nissan Terrano The low pressure port is usually located on the passenger side, near the radiator.
2. Start the engine and set the speed to 1500–2000 rpm (you can use improvised means or an assistant).
3. Turn on the air conditioner to maximum cold and set air recirculation.
4. Start refueling, opening the valve on the freon cylinder. Monitor the pressure using the pressure gauge - it should be within 25–45 psi on the low pressure side.
5. Add oil (if required). For R134a used PAG-46, for R1234yf — POE. Oil volume: 30–50 ml to full charge.

⚠️ Attention: If the system pressure exceeds 55 psi on the low pressure side, stop filling immediately! This may indicate refilling or compressor malfunction.

Typical mistakes when refilling freon and how to avoid them

Even experienced technicians sometimes make mistakes that lead to air conditioner failure. Here are the most common of them:

• ❌ Refilling without vacuum. If the system is not pumped out of air and moisture, freon will mix with water vapor, which will lead to tube corrosion And formation of ice jams.
• ❌ Using the wrong oil. For example, fill PAG-46 instead of POE for R1234yf will accelerate compressor wear by 2–3 times.
• ❌ Recharging the system. Excess freon is just as harmful as its lack - it leads to increased pressure and the risk of pipe rupture.
• ❌ Ignoring leaks. If freon leaves faster than in 2 years, it is necessary to look for and fix the leak, and not just add refrigerant.

One of the most dangerous mistakes is filling via high pressure port. This can lead to water hammer in the compressor and its immediate failure. Always connect the hoses to low pressure port (usually it is marked with a blue cap).

How to check the tightness of the system before refueling?

Freon leakage is the main reason why the air conditioner is in Nissan Terrano stops working. Before refueling, be sure to check the system for leaks. Here are some methods:

• 🔍 Visual inspection. Check all connections, pipes and radiator for oil stains (freon carries oil with it, so leaks are always visible).
• 🔍 Ultraviolet dye. Add it to the system during the previous refueling - the leak will glow under ultraviolet light.
• 🔍 Electronic leak detector. The most reliable method, but requires special equipment.
• 🔍 Immersion in water. Suitable for small parts (eg couplings).

If you find a leak, do not refill the systemuntil you fix the problem. Most often, leaks occur in the following places:

• 🛠️ Tube connections (loose nuts or cracked O-rings).
• 🛠️ Capacitor (often damaged by stones or corrosion).
• 🛠️ Evaporator (a leak inside the cabin, usually manifested by the smell of freon).

⚠️ Attention: If the leak occurs in compressor, it will have to be replaced - it cannot be repaired. Signs of a compressor malfunction: metal shavings in the oil, loud noise during operation, refusal to turn on.

How much does it cost to refill the air conditioner in a Nissan Terrano at a service station?

The cost of refilling depends on the region, type of refrigerant and complexity of the work. Below are average prices in Russia for 2026:

Service type	R134a	R1234yf
Standard refill (without diagnostics)	1500–2500 ₽	3000–4500 ₽
Filling with vacuum	2500–3500 ₽	4000–5500 ₽
Finding and eliminating leaks + refilling	4000–8000 ₽	6000–12000 ₽
Compressor replacement + refilling	15000–25000 ₽	20000–30000 ₽

You can save money if buy freon yourself and pay only for the work. For example, a balloon R134a (500 g) costs approx. 800–1200 ₽, and R1234yf — 2500–3500 ₽.

⚠️ Attention: A cheap refill (less than 1000 ₽) should alert you - most likely, they will simply add freon to you without checking the pressure and tightness. This can lead to compressor failure within a few months.

Frequently asked questions (FAQ)

Is it possible to charge the air conditioner in Terrano with your own hands without equipment?

Technically possible, but highly not recommended. Without a pressure manifold, you will not be able to control the pressure, which will lead to either undercharging (the air conditioner will blow weakly) or overcharging (risk of damage to the compressor). The minimum set for safe refilling: a freon cylinder, a pressure gauge, hoses and a vacuum pump.

How often do you need to recharge the air conditioner in a Nissan Terrano?

Under normal conditions, freon evaporates by 10–15% per year. Therefore, it is recommended to check the system every 2 years, even if there are no visible problems. If the air conditioner turns on but blows warm air, this is a sign that the freon is less than 30% of normal.

What should I do if after refueling the air conditioner works, but there is noise?

Noise can indicate several problems:

• 🔊 Air entry into the system (needs to be evacuated and refilled).
• 🔊 Compressor bearing wear (needs replacement).
• 🔊 High blood pressure due to refilling (you need to bleed off excess freon).

If the noise does not disappear, contact diagnostics - ignoring the problem will lead to compressor failure.

Can universal sealants be used to fix leaks?

Universal sealants (for example, UV dye + sealant) can help with minor leaks in rubber seals, but they ineffective if metal pipes or radiator are damaged. Moreover, some sealants clog the system, which then requires flushing. It is better to find and fix the leak mechanically.

What kind of freon is in the 2018 Terrano?

For 2018 Nissan Terrano (generation J10) officially used R134a, but if the car is intended for the European market, refueling is possible R1234yf. Check the sticker under the hood or in the service book - it should indicate the type of refrigerant. If there is no sticker, use R134a.
