What refrigerant is used in RAM 1500?
The RAM 1500 typically uses R-1234yf refrigerant in newer model years, while older trucks commonly used R-134a. The exact type depends on the year and market, so checking the under-hood label or the owner's manual is the safest way to confirm.
Refrigerant choices in RAM 1500 pickups have evolved due to environmental regulations aimed at reducing global warming potential. This article explains how the refrigerant type has changed over time for RAM 1500 models, how to verify the correct refrigerant for your truck, and what to consider if service is needed.
Refrigerant history in RAM 1500s
Here's a concise guide to what RAM 1500s typically used by era, noting that regional variations and production changes can apply.
- Older RAM 1500 models (roughly pre-2016) commonly used R-134a refrigerant.
- Transition-era RAM 1500s (around 2016–2018) may have used R-134a or R-1234yf depending on production date and market; many remained on R-134a in certain regions.
- Modern RAM 1500 models (roughly 2019 onward) primarily use R-1234yf refrigerant.
Because refrigerant labeling can vary by region and vehicle, always verify with the under-hood label, the owner's manual, or your dealer/service provider if you’re unsure.
How to verify which refrigerant your RAM 1500 uses
To confirm the exact refrigerant type for your vehicle, check several sources and indicators that practitioners rely on.
- Inspect the under-hood service label near the A/C components, which lists the refrigerant type (and the required oil) for your model.
- Consult the owner’s manual or RAM service bulletins for your model year and region.
- Look at the service ports and color codes, and, if in doubt, have a qualified automotive HVAC technician identify the refrigerant by label and system markings.
- When in doubt, don’t attempt to mix refrigerants; have the system evacuated and recharged using the correct refrigerant.
Verifying the exact refrigerant helps ensure proper charging, compatibility with the lubricant, and compliance with environmental regulations.
Where to look on the vehicle
In many RAM 1500s, the refrigerant type is indicated on a label attached to the vacuum service port or near the hood latch area; the label will specify R-134a or R-1234yf and the correct oil type.
What to know if you need A/C service
Service considerations include ensuring the system is properly evacuated, recovered, and charged with the correct refrigerant. Mixing refrigerants or using the wrong oil can damage the compressor and adapters, and may violate regulations.
- Use a certified recovery machine to evacuate the refrigerant before opening the system.
- Use the correct refrigerant type and compatible oil; never mix R-134a with R-1234yf.
- Have a professional perform recharging and any conversion work according to EPA regulations and the vehicle’s service procedures.
Professional service ensures the system seals, pressures, and lubricants are correct, preserving performance and avoiding warranty issues.
Summary
RAM 1500 refrigerant usage generally shifted from R-134a in older models to R-1234yf in newer models, driven by environmental regulations and industry transition timelines. Always verify the exact type on your vehicle’s label or manual, and rely on a qualified technician for any A/C work.
Can you recharge R-1234yf yourself?
It used to be that only professionals could recharge an AC system, but there are now kits available to do it on your own. What you'll need is: AC recharge kit with refrigerant (R-134a or R-1234yf, depending on your vehicle) Safety gloves and goggles.
Does my car use R-134a or R-1234yf?
Finding out which refrigerant your vehicle uses is easy with the help of A/C Pro®. The first place to look for this information is under the hood. Pop the hood and look for a label, which is usually white or bright yellow. On this it will either say “R-134a” or “R-1234yf,” and it may even say what the capacity is.
What kind of Freon does a Ram 1500 take?
R134a
Freon for Ram 1500 models could be R134a or R1234yf, depending on the year and build, so match your spec by shopping with your vehicle information or check the underhood label.
When did Ram start using 1234yf?
It was followed that year by the 2014 Chrysler 300, Dodge Charger and Challenger in November. The rollout continued in January, with the Dodge Dart and Ram 1500 getting the system. And by late spring, the company announced, the R-1234yf system will go into the midsize Chrysler 200, designated a 2015 model.
