Frequently Asked Questions

What does easy install mean?

Will these lines work with the new R1234yf refrigerant?

Yes. All Auto Cooling Solutions hoses meet SA J2064 standards and are compatible with both R134a and R1234yf systems.

Why Replace Your Rear AC Lines?

Rear air conditioning lines in SUVs and vans are particularly vulnerable to damage from road debris, corrosion, and wear. Common symptoms of compromised rear AC lines include loss of cooling performance in the rear cabin, visible refrigerant leaks, hissing sounds, or AC compressor cycling issues.

Installation Tips for Rear AC Line Replacement

Before beginning installation, recover all refrigerant from the system using proper AC service equipment. Inspect all connection points for corrosion or damage. Replace o-rings even if they appear intact—new seals ensure leak-free connections. After installation, vacuum the system to remove moisture before recharging with the manufacturer-specified refrigerant type and quantity.
