2017 Ram ProMaster A/C Refrigerant and Oil Guide

Quick Answer

• Refrigerant Type: R-1234yf
• System Charge: 26.5 oz (750g)
• PAG Oil Type: Mopar PAG 46
• PAG Oil Amount: 6.1 oz (180 ml)

Why R-1234yf Matters

The 2017 Ram ProMaster uses R-1234yf refrigerant, a newer, more environmentally friendly alternative to the older R-134a. While R-1234yf has a much lower global warming potential, it is also more expensive and requires special equipment for service. This means that you can't just top off your system with a can from the auto parts store. You'll need a dedicated R-1234yf recovery machine to properly service the system.

Recharge Procedure

Recharging the A/C system in your ProMaster is not a simple DIY project. It requires specialized equipment and knowledge to do it correctly and safely. Here's a high-level overview of the process:

1. Evacuate the system: This removes all of the old refrigerant and any moisture that may have entered the system. This is a critical step, as moisture can cause serious damage to your A/C components.
2. Vacuum test: A vacuum is pulled on the system to check for leaks. If the system can't hold a vacuum, it means there's a leak that needs to be repaired before proceeding.
3. Charge the system: The correct amount of refrigerant is added to the system by weight, not by pressure. This is the only way to ensure a proper charge and optimal A/C performance.

Common A/C Problems for This Vehicle

Like any vehicle, the Ram ProMaster has its share of common A/C problems. Some of the most frequently reported issues include:

• Compressor failures: The A/C compressor is the heart of the system, and it can fail for a variety of reasons, including lack of lubrication, contamination, or simple wear and tear.
• Condenser issues: The condenser is located at the front of the vehicle, making it susceptible to damage from road debris. A damaged condenser can leak refrigerant and cause the A/C system to fail.
• Evaporator leaks: The evaporator is located inside the dashboard and can develop leaks over time. This is often a difficult and expensive repair, as the entire dashboard may need to be removed to access the evaporator.

When to Call a Pro

While some basic car maintenance tasks can be done at home, A/C system service is best left to the professionals. If you're experiencing any of the following issues, it's time to take your ProMaster to a qualified A/C technician:

• A/C system is not blowing cold air
• You hear strange noises coming from the A/C system
• You see any signs of refrigerant leaks
• Your A/C system is cycling on and off frequently

Disclaimer: It is illegal to work on an A/C system without being EPA 609 certified. This is to protect both you and the environment from the harmful effects of refrigerants. If you are not certified, please take your vehicle to a qualified A/C technician.
