FreezeCar Complete R134a Repair Kit: Stop Leak + Oil + Gas

The Ultimate 1-Step Solution: Seal, Lubricate, and Refill!

Is your AC ice-cold right after a refill, but blowing warm air again a few weeks later? You don’t just need more gas—you have a leak. To fix it permanently, you need the FreezeCar All-in-One R134a Repair Kit.

We have combined three essential components—professional-grade leak sealant, system oil, and high-efficiency hydrocarbon refrigerant—into one single bottle. Plus, this kit includes the charging hose, so you have everything you need to get the job done immediately.

What’s in the Box?

  • 1x All-in-One Bottle (Gas + Leak Stop + Oil)

  • 1x Premium Charging Hose (Quick-connect for standard R134a ports)

How the 3-in-1 Formula Works:

  1. Stops Leaks: As you charge your system, our Stop Leak formula conditions dried rubber seals and O-rings, causing them to swell back to size and creating a flexible lock that keeps gas inside.

  2. Lubricates Compressor: The formula includes premium AC Oil. This tops up your system’s oil level, ensuring your compressor runs quietly and with less friction, extending its lifespan.

  3. Restores the Freeze: Simultaneously, your system is filled with our premium Hydrocarbon R134a Replacement. It is more efficient than standard chemical refrigerants, cooling your car down faster while being eco-friendly.

Simple Application:

  1. Connect: Click the included DIY hose onto the low-pressure port of your vehicle.

  2. Charge: Empty the bottle into the system while the engine and AC are running.

  3. Drive: Run the AC for 15–20 minutes to allow the Stop Leak to seal and the oil to circulate.

FreezeCar Complete All-in-One AC Repair: Stop Leak + Hydrocarbon R134a Refill

​🌬️ The Ultimate 1-Step Solution: Seal the Leak and Restore the Freeze in One Go!

Is your AC ice-cold right after a refill, but blowing warm air again a few weeks later? You don’t just need more gas—you have a leak.

Refilling a leaking system is like pouring water into a bucket with a hole in it. To fix it permanently, you need the FreezeCar All-in-One Repair & Refill. We have combined our professional-grade leak sealant and our high-efficiency hydrocarbon refrigerant into one single bottle, ensuring maximum sealing power and a pure recharge in half the time.

🛠️ How the All-in-One Formula Works:

1. The Precision Seal (Rubber Conditioning)

Most leaks in R134a systems (cars made 1992–2016) occur because rubber O-rings and seals dry out and shrink. As you charge your system, our concentrated Stop Leak formula circulates immediately, conditioning dried rubber seals and causing them to swell back to their original size. It creates a tight, flexible lock that prevents your new gas from escaping.

2. The High-Performance Cool (Eco-Refill)

Simultaneously, your system is filled with our premium Hydrocarbon R134a Replacement.

  • Superior Cooling: Hydrocarbon molecules are more efficient than old chemical refrigerants, meaning your car cools down faster.

  • Eco-Friendly: A natural, non-toxic mixture with near-zero global warming potential.

  • Energy Saving: The lighter gas reduces compressor friction, improving fuel economy and reducing engine drag.

Why Choose the FreezeCar All-in-One Bottle?
