Ford Aerostar A/C Suction Line Hoses
Ford Aerostar A/c suction line hoses
Starting at $52.95, AutoBuffy stocks 1 A/C suction line hoses from UAC for the Ford Aerostar. The suction line carries low-pressure refrigerant vapor from the evaporator back to the compressor. A cracked, collapsed, or leaking hose starves the compressor of refrigerant, causing warm air from the vents and potential compressor damage if left unaddressed.
Signs your Ford Aerostar needs a new A/C suction line hose
- Warm or room-temperature air blowing from vents even when A/C is set to maximum cold
- Visible oily residue or refrigerant staining along the hose body, fittings, or connections — a telltale sign of a slow leak
- Low-side pressure reading consistently below the normal range when checked with an A/C manifold gauge set
- A/C compressor cycling on and off rapidly (short-cycling) because refrigerant charge is too low to maintain proper pressure
- Hissing or bubbling sound near the firewall or evaporator area when the A/C is running
- Collapsed, cracked, or hardened hose visible on inspection, especially near heat sources or tight bends
Which A/C suction line hose should you buy for your Ford Aerostar?
The main decision is between an OE-equivalent replacement hose and an upgraded barrier-style hose, and whether you need an assembly with fittings pre-attached or a hose-only section. Make sure the hose you choose matches the correct routing position — suction (low-pressure) and discharge (high-pressure) hoses are not interchangeable.
OE-Equivalent Replacement Hose Assembly
Best for
Straightforward like-for-like swap with pre-attached fittings
What you get
Hose crimped with factory-spec fittings, correct diameter and length for the Ford Aerostar, ready to install without fabrication
Barrier-Style Hose Assembly
Best for
High-mileage vehicles or those in hot climates where permeation is a concern
What you get
Multi-layer construction with an inner barrier layer that minimizes refrigerant permeation and extends service life over standard rubber hose
Hose with Integrated Receiver/Accumulator Port
Best for
Vehicles where the suction line includes a service port or sensor bung
What you get
Drop-in fit that retains the low-side Schrader valve port and any pressure sensor provisions already present on the Ford Aerostar
Universal Hose with Field-Attached Fittings
Best for
Custom repairs, minor section replacements, or when an OE assembly is discontinued
What you get
Bulk hose cut to length with separate crimp or reusable fittings — requires a hose crimper and correct fitting spec; lowest upfront cost but more labor

Replacing an A/C suction line hose on a Ford Aerostar

Have a certified technician or a shop with recovery equipment discharge the refrigerant before you begin — releasing refrigerant is illegal and dangerous. With the system depressurized, disconnect the old hose at both ends using the correct fitting disconnect tool, transfer any O-rings to the new hose using fresh O-rings lightly coated in refrigerant-compatible oil, and route the new hose following the original path. After all connections are tight, evacuate the system under vacuum, confirm it holds, then recharge with the refrigerant type specified for the Ford Aerostar.
Frequently asked questions
How much does it cost to replace A/C suction line hoses on a Ford Aerostar?
Parts start at $52.95 on AutoBuffy for the Ford Aerostar. A shop will typically add one to two hours of labor on top of the part cost, plus refrigerant recovery, evacuation, and recharge fees. Doing the job yourself saves the labor charge but you still need refrigerant service equipment or a recharge kit.
Can I drive my Ford Aerostar with a leaking A/C suction line hose?
You can drive short-term, but it is not advisable. A leaking suction line allows refrigerant and lubricating oil to escape together. Once oil level in the system drops, the compressor runs dry and can seize — turning a low-cost hose repair into a full compressor replacement.
How long does an A/C suction line hose last on a Ford Aerostar?
Most rubber A/C hoses last somewhere between 10 and 15 years, though heat cycles, ozone exposure, and vibration accelerate deterioration. On older vehicles inspect hoses for hardness, cracking near the crimped fittings, and oily residue at every major service interval, especially if refrigerant charge keeps dropping without an obvious leak elsewhere.
Do I need to evacuate and recharge the A/C system after replacing the suction line hose on a Ford Aerostar?
Yes, always. Opening any fitting in a closed A/C system introduces moisture and air. Before reconnecting the new hose, the system must be evacuated with a vacuum pump for at least 30 minutes to remove contaminants, then recharged with the correct refrigerant type and quantity specified for the Ford Aerostar.
What is the difference between the A/C suction line and the discharge line on a Ford Aerostar?
The suction line is the low-pressure side, carrying cool refrigerant vapor from the evaporator to the compressor inlet. It is usually the larger-diameter of the two hoses and will feel cold and may sweat during operation. The discharge line is the high-pressure side leaving the compressor; it is smaller and gets very hot.
Will stop-leak additives fix a leaking A/C suction line hose on a Ford Aerostar?
Stop-leak products are not a reliable fix for a physically damaged or permeating hose and can contaminate the system's expansion valve, accumulator, and compressor. They may also void warranty on recently replaced components. Replace the hose and recharge the system properly rather than risking additional damage to more expensive components.
