51107 Fan, engine cooling (OSSCA OE-Spec Replacement)

The 51107 Fan, engine cooling is a OSSCA cooling fan listed under our
Cooling Fan 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.

How It Works

The engine cooling fan draws air through the radiator and intercooler matrix when vehicle road speed is insufficient to maintain adequate airflow — primarily at idle, in traffic, and at low speed. Viscous-coupled mechanical fans engage above a coolant temperature threshold; electric fans are triggered by a thermoswitch or the ECU based on coolant temperature, AC compressor demand, and engine load.

Signs You Need a Replacement

An inoperative electric fan allows coolant temperature to rise in stop-go traffic and when the AC is running with the vehicle stationary. A seized viscous-coupled fan can cause belt breakage or overload the water pump shaft bearing. Noise at speed that disappears at higher speed often points to a failing fan clutch.

Brand & Manufacturing Authority

This cooling fan is manufactured by OSSCA, a recognised supplier
to the automotive aftermarket. The part number 51107 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 glass-filled polyamide fan blades on an aluminium or steel hub, with either a viscous fluid coupling or an electric motor and shroud assembly. 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 cooling fan 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.

Product Specifications

Cross-Reference Compatibility Table

Match your existing part number against this table before ordering. All data is drawn directly
from the manufacturer’s own cross-reference documentation.

Installation & Safety Notes

Check the fan motor and thermoswitch circuit before condemning the fan, to avoid replacing a mechanical component when the fault is electrical. Ensure the fan shroud seals correctly against the radiator face to prevent recirculation. Always follow your vehicle manufacturer’s torque specifications and service
manual procedure. For the engineering standards that govern this part category, see the
SAE International cooling system standards.

Quality Assurance

We verify every listing’s cross-reference data against the manufacturer’s own catalog before
publishing. We sell OSSCA parts because the brand has a documented track record in the
cooling fan category. If a part number doesn’t match your vehicle after
checking the table above, contact us and we’ll find the correct one.

Choosing the Right Cooling Fan — A Buyer’s Guide

Shopping for a cooling fan 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 cooling fan, 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 OSSCA 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 cooling fan 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.
