Honda CR-Z A/C Refrigerant Suction Hoses
Honda CR-Z A/c refrigerant suction hoses
Starting at $22.95, AutoBuffy stocks 2 A/C refrigerant suction hoses across Four Seasons and GPD and more. The suction hose carries low-pressure refrigerant vapor from the evaporator back to the compressor. When it cracks, collapses, or leaks, the system loses refrigerant, the compressor runs dry, and your Honda CR-Z stops cooling entirely.
Signs your Honda CR-Z needs a new A/C refrigerant suction hose
- Warm or room-temperature air blowing from vents even with A/C set to maximum cold
- Visible oily residue or refrigerant staining along the hose body, fittings, or nearby components
- A/C compressor cycling on and off rapidly or refusing to engage due to low system pressure
- Hissing or bubbling sound near the firewall or compressor when the A/C is running
- Collapsed, kinked, or visibly cracked rubber section on the low-pressure side of the hose
- A/C performance that deteriorates quickly after a refrigerant recharge, indicating an active leak
Which A/C refrigerant suction hose should you buy for your Honda CR-Z?
The suction hose is a low-pressure line, but fit and material quality still matter — a hose that does not seat correctly at the fittings will leak refrigerant immediately. Your main decisions are OE-spec replacement versus a universal repair hose, and whether you need a hose assembly with fittings already crimped or a bulk hose you cut to length.
OE-spec direct-fit assembly
Best for
Straightforward replacement with no fabrication
What you get
Pre-crimped fittings, correct routing length, and gaskets matched to your Honda CR-Z's ports
OEM-equivalent aftermarket assembly
Best for
Budget-conscious repair with reliable sealing
What you get
Comparable materials and fitment to factory spec, often at a lower cost than dealer parts
Universal bulk barrier hose + fittings
Best for
Custom routing, hard-to-find applications, or shop use
What you get
R-134a / R-1234yf rated multi-layer barrier hose sold by the foot; requires a hose crimper and separate fittings
Hose repair kit (splice fitting)
Best for
Repairing a localized cut or pinhole on an otherwise sound hose
What you get
Compression or barbed splice fitting and clamps; a temporary fix — full replacement is preferred for long-term reliability

Replacing the A/C refrigerant suction hose on a Honda CR-Z
Advanced⏱ 1–2 hours (plus refrigerant recovery and recharge time)A/C refrigerant recovery machine (or shop service for recovery/recharge)Line disconnect tools (spring-lock or block-fitting style, matched to hose size)Combination wrench or flare-nut wrench setVacuum pump and manifold gauge setSafety glasses and nitrile gloves
Before any work begins, have a certified technician recover all refrigerant from the system — never open an A/C line under pressure. With the system empty, use the correct disconnect tool for your fitting style to release both ends of the suction hose, then route the new hose into position and seat the fittings fully before tightening. Once the hose is secure, the system must be pulled into a deep vacuum to remove moisture and air, then recharged to factory pressure specification before the A/C will function correctly.
Frequently asked questions
How much does it cost to replace A/C refrigerant suction hoses on a Honda CR-Z?
The part itself starts at $22.95 on AutoBuffy. Factor in a shop refrigerant recovery and recharge service, which typically adds to the total cost. DIY installation saves on labor, but you will still need a certified shop or AC machine to evacuate and recharge the system after the hose is replaced.
Can I drive my Honda CR-Z with a leaking A/C suction hose?
You can drive short distances, but continuing to run the A/C with a leaking suction hose is not recommended. Low refrigerant starves the compressor of the oil it carries through the system, leading to compressor failure. A replacement compressor costs significantly more than a hose, so addressing the leak promptly protects the rest of the system.
Do I need to evacuate the system before replacing the suction hose on my Honda CR-Z?
Yes. Refrigerant must be recovered by a certified technician or with certified equipment before opening any A/C line. Venting refrigerant to the atmosphere is illegal under EPA regulations. After the new hose is installed, the system must be evacuated with a vacuum pump and then recharged to the correct pressure before it will cool properly.
How long does an A/C refrigerant suction hose last on a Honda CR-Z?
Most OE-quality suction hoses last many years under normal use, but the rubber barrier layer degrades over time from heat, ozone, and refrigerant exposure. Age, high-heat engine bays, and infrequent A/C use that allows seals to dry out all accelerate wear. Inspect the hose for soft spots, surface cracking, or oily film during any major service.
Is the suction hose the same as the discharge hose on a Honda CR-Z?
No. The suction hose is the low-pressure line running from the evaporator to the compressor inlet. The discharge hose is the high-pressure line leaving the compressor outlet. They are different sizes, rated for different pressures, and are not interchangeable. Confirm which side of the compressor your hose connects to before ordering.
Will any refrigerant hose fit my Honda CR-Z, or does it have to be vehicle-specific?
Routing length, inner diameter, fitting type, and port orientation are all vehicle-specific. A hose from a different application will rarely align with mounting brackets or reach both ports correctly, and mismatched fittings will leak. Use a direct-fit assembly confirmed for your Honda CR-Z, or have a shop fabricate a custom hose using the correct diameter barrier hose and proper crimped fittings.
