Changan CS35 Radiator Fan – Part No.: S101030-0800

Think of this as your Changan CS35’s “engine bodyguard against overheating”—not just a regular fan. It’s a tough, purpose-built unit with slim, rigid plastic fan blades (usually 4 to 6 of them) and a motor wrapped in heat-resistant metal. You’ll find it tucked right behind the radiator in the engine bay, sitting ready to jump into action when your car needs it most.

Here’s how it works: Your CS35’s engine generates heat as it runs, and the radiator uses coolant to soak that heat up. But when you’re stuck in traffic, driving on a hot day, or going for a long trip, the radiator can’t always get enough fresh air to cool the coolant down on its own. That’s when this fan kicks in—it blows a steady stream of air over the radiator, speeding up coolant cooling so the engine stays at a safe temperature. Skip this fan, and your engine could overheat fast—leading to breakdowns or even expensive fixes like replacing warped parts.

This fan is made only for the Changan CS35—so always check your vehicle’s VIN to make sure it’s the right fit. Changan designed it to match the CS35 perfectly: the fan blades are sized to cover the radiator just right (so no air gets wasted), the motor’s power matches how much heat the CS35’s engine puts out (no too-weak or too-strong cooling), and the wiring plugs right into the car’s ECU (the “brain” that controls when the fan turns on or off). Grab a generic fan or one for another car? You’ll run into issues: blades that are too small (not enough air), a motor that can’t keep up (still overheats), or wiring that doesn’t connect (fan never turns on).

1. What It Actually Does (3 Big Jobs)

This fan isn’t just about cooling—it pulls double duty to keep your CS35 running smoothly:

Cools the engine automatically: The CS35’s ECU keeps an eye on engine temperature. When it hits 90–95°C (the “too-hot” mark), the ECU tells the fan to turn on. Once the engine cools down a bit, the fan shuts off by itself—saving battery power too. No need for you to flip a switch; it’s all automatic.

Makes your AC colder, faster: In summer, when you crank the AC, the AC system has a part called a condenser (right next to the radiator) that also needs cooling. The fan blows air over both the radiator and the condenser, helping the AC make cold air quicker—even when you’re stopped in traffic with no wind.

Stops expensive engine damage: Overheating is one of the worst things for an engine. It can warp cylinder heads, break gaskets, or ruin parts that cost a lot to replace. This fan ensures the coolant stays cool enough to keep the engine from getting too hot—stopping those problems before they start.

This S101030-0800 fan only works with the Changan CS35—don’t try to use it on other cars:

Fits: All Changan CS35 models (matches the radiator size, ECU wiring, and engine heat needs—confirm with VIN).

Doesn’t fit:

Other Changan models (like CS75, Eado, or UNI-T): Their radiators are different sizes, motors need more/less power, or wiring doesn’t match (fan won’t work or fit).

Cars from other brands: Even if the fan looks the same, their cooling systems and ECUs are different (fan might not turn on, or overcool the engine).

CS35s with modified cooling: If you put an aftermarket radiator or upgraded engine parts in your CS35, the original fan can’t keep up (still overheats).

 Installing & Taking Care of It

Installation: Let a Pro Do It (Here’s Why)

Replacing this fan means working with electrical wires and the engine bay—DIY can lead to mistakes:

First, the pro will turn off the engine and disconnect the battery (so no shocks). Then they’ll find the fan behind the radiator, unplug the wiring, and take off the bolts/clips holding it in place.

They’ll pull the old fan out gently (being careful not to bend the radiator’s thin fins) and clean any debris off the radiator (clogged fins make cooling worse).

Next, they’ll line up the new S101030-0800 fan with the radiator, bolt it in, and plug the wiring back in (making sure it clicks).

Finally, they’ll reconnect the battery, start the engine, and use a tool to check if the fan turns on when the engine gets hot. They’ll also listen for rattles—making sure everything’s tight.

Taking Care of It (Easy Checks)

Keep this fan in good shape with simple maintenance:

Clean every 3 months: Use compressed air or a soft brush to wipe dust, bugs, or leaves off the blades and radiator fins (clogged blades can’t move air).

Check blades once a year: Look for cracks or chips—damaged blades wobble, make noise, or don’t cool well (replace the fan if blades are broken).

Listen for weird noises: If the fan makes grinding or squealing sounds, the motor is going bad—replace it fast to avoid burnout.

Check the wiring every 6 months: Make sure the plug is tight and not corroded (rusty wires make the fan work on and off).

Summary: Changan CS35 Radiator Fan (S101030-0800)

Exclusive to Changan CS35 (confirm fitment via VIN), this fan has 4–6 slim, rigid plastic blades and a heat-resistant metal motor housing, mounted behind the radiator in the engine bay.

Controlled by the CS35’s ECU, it turns on at 90–95°C to blow air over the radiator (cooling coolant to prevent engine overheating) and shuts off when cool. It also boosts AC cooling by cooling the nearby condenser and avoids costly engine damage from overheating.

It fits all CS35 variants but not other Changan models (e.g., CS75, Eado), non-Changan vehicles, or CS35s with modified cooling systems.

Professional installation is recommended (involves battery disconnection, fan replacement, and function testing). Maintenance tips: clean blades/fins every 3 months, check blades yearly for cracks, listen for abnormal motor noise, and inspect wiring every 6 months. Original fans ensure proper fit and durability; aftermarket ones risk weak airflow or poor ECU compatibility.
