🌡️🔌 Radiator Fan Wiring Diagram Explained 🚗⚡
This wiring setup shows how the radiator fan system keeps your engine cool and safe. The fan works automatically with the help of the relay, ECU, and temperature sensor.
🔎 How It Works:
1️⃣ Battery & Fuse Box 🔋

Battery supplies main power.

Power passes through the fuse box for safety.

2️⃣ Relay (4-pin) ⚡

Pin 30 → Battery (power in).

Pin 87 → Radiator fan (power out).

Pin 86 → Trigger from ECU.

Pin 85 → Ground.
👉 The relay lets the fan run on high current without stressing the ECU.

3️⃣ ECU (Engine Control Unit) 💻

Reads signals from the coolant temperature sensor.

Activates the relay when temperature goes above the limit.

4️⃣ Radiator Fan 🌀

When the relay switches, power flows to the fan.

Fan pulls air through the radiator to cool the engine coolant.

5️⃣ Engine Coolant Temperature Sensor 🌡️

Continuously monitors coolant temp.

Sends a 5V signal to the ECU for fan control.

✅ Key Function:
The system makes sure the fan runs only when needed, preventing overheating 🔥 while saving battery power 🔋.

⚙️🔧 How To Understand the Main Parts of Rear Axle Assembly 🚙💨
The rear axle is a crucial part of the drivetrain. It transfers power from the engine & transmission to the rear wheels, supports the vehicle’s weight, and ensures stable driving on the road 🛣️✨
👉 In rear-wheel-drive cars, the rear axle is the driving axle, delivering torque to the wheels. Depending on the design, it can be live (powered) or dead (unpowered), and may be independent or solid.
🔩 Key Parts of Rear Axle Assembly:
1️⃣ Filler Plug 🛢️ – Check or refill differential oil.
2️⃣ Drain Plug 💧 – Drain old differential fluid.
3️⃣ Differential ⚙️ – Lets wheels rotate at different speeds during turns.
4️⃣ Leaf Spring 🌀 – Suspension system that stabilizes the car on uneven roads.
5️⃣ Wheel 🛞 – Connects to the hub & moves the car.
6️⃣ Differential Casing 🛡️ – Protects and houses the differential gears.
7️⃣ Axle Shaft 🔄 – Transfers power from transmission to wheels.
8️⃣ Propeller Shaft (Drive Shaft) 🚀 – Carries torque from engine to rear axle.
9️⃣ Axle Bearing 🛠️ – Reduces friction & supports wheel rotation.
🔟 Axle Case 🏋️ – Strong housing that contains the axle assembly.
⚡ In short: The rear axle = Power + Strength + Stability + Smooth Driving! 🚘👌
