The 4A026 Compressor, Air Conditioning is a A.Z. Meisterteile ac compressor listed under our
AC Compressor category at
CG Auto Parts Shop. Every listing includes a full manufacturer cross-reference
table so you can confirm fitment by part number before you order.
4A026 Compressor, Air Conditioning — function and selection
The AC compressor is the pressure-generating heart of the refrigeration circuit. A belt-driven (or electrically driven on hybrid/EV systems) scroll, swash-plate, or rotary-vane mechanism compresses low-pressure refrigerant vapour from the evaporator into high-temperature, high-pressure gas, which is then cooled and condensed in the condenser before expanding across the expansion valve into the evaporator.
Signs You Need a Replacement
Warm air from the vents is the primary symptom. A rattling, grinding, or seizing noise as the magnetic clutch engages confirms internal compressor damage. Visible refrigerant oil residue around the shaft seal indicates a seeping seal. Running a system with a low refrigerant charge for an extended period is the leading cause of compressor failure because the refrigerant also carries the lubricating oil.
Brand & Manufacturing Authority
This ac compressor is manufactured by A.Z. Meisterteile, a recognised supplier
to the automotive aftermarket. The part number 4A026 identifies this specific
unit in the manufacturer’s own catalog. It is supplied new — not remanufactured — and is backed by our
warranty policy.
Material & Construction
Built from aluminium housing with an internal scroll or swash-plate mechanism, magnetic clutch assembly, and shaft seal rated for the refrigerant type (R-134a or R-1234yf depending on vehicle specification). This construction is chosen to match or exceed the OE
specification it replaces under the same load, temperature, and service conditions.
Fitment Confidence
Year-make-model filters alone can miss mid-year production changes that affect fitment. The safest
method is to match the part number stamped on your existing ac compressor against the
cross-reference table below. If you can’t locate your existing part number, send your vehicle VIN
through our contact page and we’ll confirm before you order.

Installation & Safety Notes
Evacuate the system before removal. Replace the receiver-drier or accumulator alongside the compressor. Add the correct amount of PAG or POE oil to the new compressor. Recharge to the manufacturer’s weight specification — over- or under-charging damages the new unit. Always follow your vehicle manufacturer’s torque specifications and service
manual procedure. For the engineering standards that govern this part category, see the
SAE mobile air conditioning standards.

Choosing the Right AC Compressor — A Buyer’s Guide
Shopping for a ac compressor by part number rather than by vehicle
model alone is the most reliable way to avoid a fitment mismatch. A year-make-model filter is a
starting point, but the same vehicle model can use different component specifications depending on
trim level, engine variant, and production date. The cross-reference table above is built from
the manufacturer’s own part-number data, which means the relationship between this part and the
vehicle application is confirmed at the component level rather than inferred from model data.
When you receive the new ac compressor, compare it physically against
the old part before installation — check overall dimensions, mounting hole positions, and connector
orientation. A direct visual comparison catches any discrepancy before time is invested in
disassembly. If anything doesn’t match despite the part number confirming correctly, contact us
before installing, since we can usually resolve fitment questions the same day.
We source our A.Z. Meisterteile parts directly through authorised supply
channels to ensure you receive the genuine part that the cross-reference table confirms. Aftermarket
quality varies enormously by brand; listing the actual manufacturer — rather than a generic
“compatible with” label — is how we give you the information needed to make a confident buying
decision. The About Us page explains our approach to sourcing and
part-number verification in more detail.
After Installation — What to Check
Once the new ac compressor is fitted and torqued to specification,
a brief test drive under controlled conditions is the best way to confirm the repair is successful
before returning the vehicle to normal use. Listen for any new noises from the affected area at low
speed over a rough surface, and confirm that the system behaviour feels correct. For suspension and
steering components, a wheel alignment check immediately after installation is strongly recommended,
since even a correctly fitted new part can require alignment correction compared to the worn part
it replaced. For braking components, a proper bed-in procedure — a series of graduated stops from
road speed — transfers an even layer of friction material and settles the new components before
maximum braking loads are applied.
Keep the installation date and part number noted in your service records. This information is
required if a warranty claim becomes necessary, and it makes future parts sourcing straightforward
since you’ll have a confirmed part number on file. Our warranty
policy page specifies the documentation needed to support a claim.
