These instructions apply to the Toyota Hilux Mk8 (AN120/AN130) 2016-2024.
For other models, please choose your vehicle here.
If the air conditioning in your Hilux is blowing warm, it usually needs re-gassing. The eighth-generation Hilux uses the newer R-1234yf refrigerant — not the older R-134a — so it needs the right gas and the right equipment.
Hilux air-con specification
- Refrigerant type: R-1234yf
- Charge amount: 500 ± 30 g (per the under-hood A/C label)
- Compressor oil: Toyota ND-OIL 12 (PAG-type)
These figures come from the A/C caution label in the engine bay. Always use the amount stamped on your own vehicle’s label, as it is the definitive figure.
Is re-gassing a DIY job?
Not really. R-1234yf systems must be recovered, vacuumed and recharged by weight using dedicated R-1234yf equipment — the cheap DIY top-up cans sold for older R-134a cars are not suitable and can over- or under-charge the system. R-1234yf is also mildly flammable, so recharging is a job for an air-conditioning specialist with the correct machine.
What you can do yourself: run the A/C for about 10 minutes at least once a fortnight (even in winter) to keep the compressor seals lubricated, keep the pollen filter fresh for good airflow, and keep the condenser in front of the radiator clear of leaves and bugs.
FAQ
Can I use R-134a instead? No — the systems are not compatible. Using the wrong refrigerant damages the compressor and is illegal.
How often does A/C need re-gassing? A healthy system loses only a little gas a year; if it needs frequent re-gassing there is a leak that should be found and fixed.
