FreezeCar Complete 2-Step AC Repair Kit: Stop Leak + Hydrocarbon R134a Refill

🌬️ The Ultimate 2-in-1 Solution: Repair Leaks First, Then Restore the Freeze!

​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 2-Step Repair & Refill Kit. Unlike “all-in-one” cans that dilute the solution, our kit provides two separate, professional-grade bottles to ensure maximum sealing power followed by a pure, high-efficiency recharge.

​Step 1: The Stop Leak (Bottle A)

The Precision Repair.

Most leaks in R134a systems (cars made 1992–2016) happen because rubber O-rings and seals dry out and shrink over time.

  • Restores Seals: Our concentrated Stop Leak formula circulates through the system, conditioning dried rubber seals and causing them to swell back to their original size.
  • Stops the Drain: By rejuvenating the rubber, it creates a tight, flexible lock that prevents your new gas from escaping.
  • Compressor Safe: Contains no clogging particles or glues—only safe, oil-based conditioners.

​Step 2: The Eco-Refill (Bottle B)

The High-Performance Cool.

Once the system is sealed, it’s time to fill it with our premium Hydrocarbon R134a Replacement.

  • Green & Clean: A natural, non-toxic hydrocarbon mixture that is eco-friendly and has near-zero global warming potential.
  • Superior Cooling: Hydrocarbon molecules are more efficient than old chemical refrigerants, meaning your car cools down faster and vents colder air.
  • Energy Saving: The lighter gas reduces friction in your compressor, reducing engine drag and improving fuel economy.

R12 AC Restoration Kit (Stop Leak + Refill + Adapter)

 

Bring the chill back to your classic ride—and keep it there.

Owning a vehicle manufactured before 1993 often means dealing with two problems: an AC system that has leaked out over the years, and incompatible R12 service ports. The Freeze Car Restoration Kit solves both problems in one box.

We have combined our premium refrigerant with our powerful Stop Leak conditioner and the necessary hardware to make this the easiest “Drop-in” solution on the market.

Why this kit is essential for older cars:

 

  1. It Stops the Leaks: In older cars, rubber seals and O-rings dry out and shrink, causing gas to escape. Just refilling the gas isn’t enough—it will leak out again. This kit includes a dedicated can of Freeze Car Stop Leak to recondition and swell those seals, creating a tight system.

  2. It Connects Perfectly: Modern hoses don’t fit classic cars. We include the specific R12 Retrofit Adapter (Screw-on to Quick-Connect) so you can hook up our hose to your car’s low-pressure port instantly. No tools required.

  3. It Replaces R12 Safely: Our hydrocarbon formula is non-corrosive and operates at lower pressures than modern gas, preserving your vintage compressor while blowing ice-cold air.

What’s in the Box?

 

  • 1 x Can of FreezeCar Universal Refrigerant: High-performance, eco-friendly cooling gas.

  • 1 x Can of FreezeCar Stop Leak (Rubber): To seal leaks and lubricate the system.

  • 1 x Premium DIY Hose: With an integrated pressure gauge to measure levels accurately.

  • 1 x R12 Retrofit Adapter: Converts your old R12 screw-port to a modern quick-connect port.

How to use:

 

  1. Screw the R12 Adapter onto your car’s low-pressure port.

  2. Connect the hose and fill the Stop Leak can first to condition the seals.

  3. Switch cans and fill the Refrigerant until the gauge is in the blue zone.

  4. Enjoy a leak-free, ice-cold classic car!

Note: This kit is designed for systems that are low on gas or empty due to minor rubber leaks. It cannot repair broken metal components.
