Product Introduction

• Structure: An electronically controlled viscous clutch integrated with a multi-groove drive pulley and mounting bracket. It features an aluminum housing, a precision-engineered internal fluid chamber, and an integrated electronic control module with temperature sensors. The assembly includes a sealed wiring harness for power and signal transmission.

• Performance: The electronic control module adjusts clutch engagement based on real-time coolant temperature, engine load, and ambient conditions. This allows the fan to operate at variable speeds, reducing unnecessary power draw and improving fuel economy while ensuring reliable cooling under heavy loads.

Core Function

1. Dynamic Speed Control: Adjusts fan speed automatically to maintain optimal engine operating temperatures, preventing both overheating and unnecessary cooling.

2. Fuel Efficiency Improvement: Reduces parasitic power loss by disengaging the fan when maximum cooling is not required, lowering fuel consumption and engine wear.

3. Durability & Protection: The sealed housing and integrated pulley design protect internal components from contamination, ensuring consistent performance and extending service life.

Fan Clutch 1001187115 WEICHAI – OEM-Grade Engine Cooling for Heavy-Duty Trucks

When your WEICHAI engine runs hot under heavy loads, the fan clutch is the silent guardian that keeps temperatures in check. The Fan Clutch 1001187115 WEICHAI from METTLEAD Truck Parts delivers precise thermal regulation, engaging and disengaging the cooling fan exactly when your engine demands it. Built to OEM specifications and factory-direct priced, this fan clutch eliminates overheating risks while reducing parasitic power loss — so your fleet stays on the road and your maintenance budget stays intact.

Key Functions and Benefits

Intelligent Thermal Management

This fan clutch responds to real-time engine temperature changes through a bimetallic thermal sensor. It engages the cooling fan only when coolant temperatures rise above the optimal threshold, and disengages smoothly once temperatures normalize. This on-demand operation prevents overcooling during cold starts and reduces unnecessary fuel consumption by up to 3–5%.

Extended Component Lifespan

By decoupling the fan from the engine when cooling is not required, the 1001187115 fan clutch reduces mechanical stress on the water pump bearing, fan belt, and radiator assembly. Operators typically report 30–40% longer service intervals on associated cooling system components.

Noise and Vibration Reduction

A disengaged fan means a quieter cab environment. Drivers experience noticeably lower noise levels during highway cruising, which contributes to reduced fatigue on long-haul routes.

Direct OEM Replacement

Engineered to match WEICHAI original equipment dimensions, torque ratings, and mounting patterns, this fan clutch drops into place without modifications. No adapter brackets, no guesswork — just bolt-on fitment that your technicians will appreciate.

Technical Specifications

Application Scenarios and Compatible Vehicle Models

Whether your trucks haul aggregate across African mining roads or deliver goods through Southeast Asian monsoon heat, this fan clutch maintains thermal equilibrium where it matters most.

OEM/ODM Capability

White-Label and Custom Packaging

METTLEAD supports distributors and fleet operators who need branded packaging solutions. We offer white-label service on the Fan Clutch 1001187115 WEICHAI — your logo, your box design, your brand identity on every unit shipped to your warehouse.

Strict Quality Control

Every fan clutch undergoes a multi-stage inspection process before it leaves our facility:

1. Raw material verification and dimensional inspection
2. Silicone fluid viscosity testing at controlled temperatures
3. Engagement/disengagement cycle testing (minimum 500 cycles)
4. Dynamic balance testing to prevent vibration at operating speeds
5. Final visual and packaging inspection

Factory-Direct Pricing Advantage

By sourcing directly from METTLEAD, you bypass middlemen and import agents. Our procurement managers consistently report 15–25% cost savings compared to third-party trading companies — without compromising on part quality or delivery reliability.

Frequently Asked Questions About Fan Clutch 1001187115 WEICHAI

How do I know if my WEICHAI fan clutch needs replacement?

Common symptoms include the fan spinning freely when the engine is hot (clutch not engaging), excessive engine temperature warnings, or a fan that remains fully engaged at all times causing high fuel consumption and noise. If the silicone fluid leaks from the housing, replacement is immediate.

Is this fan clutch 1001187115 compatible with non-WEICHAI engines?

No. The 1001187115 fan clutch is specifically designed for WEICHAI WP10, WP12, and WP13 engine series. The mounting flange pattern and thermal engagement characteristics are calibrated for these engines. Using it on incompatible engines may result in improper cooling or mechanical failure.

What is the difference between a viscous fan clutch and an electromagnetic fan clutch?

The 1001187115 uses a viscous (silicone oil) mechanism that engages gradually based on temperature. Electromagnetic clutches engage instantly via an electrical signal. Viscous clutches like this one are preferred in heavy-duty applications for their mechanical simplicity, durability, and lower maintenance requirements.

How long does the fan clutch 1001187115 WEICHAI typically last?

Under normal operating conditions — proper coolant levels, clean radiator fins, and no external contamination — this fan clutch delivers reliable service for 80,000 km or more. Harsh environments with extreme dust or frequent thermal shock may reduce service intervals.

Can I test the fan clutch before installation?

Yes. With the engine cold, the fan should spin with moderate resistance. When heated (using a heat gun on the bimetallic spring area to approximately 85°C), the fan should lock and resist spinning. If it spins freely in both states, the clutch is defective.
