Product Introduction

• Structure: Made of high-quality EPDM rubber reinforced with synthetic fiber braiding, with a precision-molded S-bend shape to fit the cab’s under-dash layout. It features barbed ends with white alignment marks for secure connection to the heater core and engine coolant lines, and the surface has a textured finish for enhanced grip during installation.

• Performance: The EPDM rubber material resists high temperatures (up to 120℃) and corrosion from engine coolant, maintaining flexibility even in cold weather (-40℃). The fiber braiding provides structural reinforcement to prevent bursting under pressure, while the barbed ends ensure a tight, leak-free seal. The precision-molded shape eliminates the need for additional bends or adapters, reducing installation complexity.

Core Function

1. Coolant Transfer: Carries hot engine coolant from the engine to the cab’s heater core, providing the heat source for the cab’s heating and defrosting functions.

2. Pressure Resistance: The reinforced construction withstands the pressure fluctuations of the engine cooling system, preventing leaks and ensuring reliable coolant flow.

3. Temperature Stability: Maintains flexibility and structural integrity across extreme temperature ranges, ensuring consistent performance in both summer and winter driving conditions.

Frequently Asked Questions About Water Inlet Pipe 812W61960-0007

What exactly does the Water Inlet Pipe 812W61960-0007 do in a Sitrak truck?

This water inlet pipe serves as the coolant entry point for the cab’s air conditioning and heating system. It channels warm engine coolant into the HVAC heat exchanger inside the cabin, which allows the climate control system to generate heat for the driver compartment. Without a properly functioning inlet pipe, you’ll notice reduced heating performance or coolant leaks around the cab connection points.

How do I know if my Water Inlet Pipe 812W61960-0007 needs replacement?

Common signs include visible coolant drips or stains near the pipe connections, a sweet coolant smell inside the cab, reduced heater output even when the engine is at operating temperature, or visible corrosion and pitting on the pipe’s surface. If the pipe has been in service for several years or the truck has high mileage, preventive replacement during scheduled maintenance is a wise approach.

Is this part an original Sinotruk piece or an aftermarket replacement?

This is an aftermarket OEM-specification replacement. That means it’s manufactured to match the exact dimensions, material grade, and performance characteristics of the original Sinotruk part — but at a significantly lower cost. Our strict quality control process ensures every unit meets or exceeds the fitment and durability standards you’d expect from a genuine part.

Can I install the Water Inlet Pipe 812W61960-0007 myself, or does it require specialist tools?

For an experienced truck mechanic, installation is straightforward. You’ll need to drain or reduce the coolant level, disconnect the old pipe at both mounting points, and install the new one with fresh seals or O-rings if applicable. Standard hand tools are typically sufficient. However, because you’re working with the cooling system, we recommend having a torque specification reference handy to avoid over-tightening the connections.

Will this water inlet pipe fit other Sinotruk models besides Sitrak?

Part number 812W61960-0007 is specifically cataloged for Sinotruk Sitrak trucks. While some Sinotruk models share components, we strongly recommend verifying the part number against your specific vehicle’s parts manual before ordering. If you’re unsure, our team can help you cross-reference — just reach out to us.

What’s the typical lead time for shipping this part internationally?

Lead times depend on order volume and destination. For stocked items, we can typically dispatch within 1–3 business days. International shipping via express courier takes 5–7 days to most regions, while sea freight is more economical for bulk orders but takes longer.
