Application: Which Vehicles Use the 711W61900-7130 AC Assembly?

The AC Assy 711W61900-7130 is specifically engineered for the Sinotruk Sitrak series of heavy-duty trucks. These vehicles are widely deployed across demanding transportation environments worldwide. More specifically, this assembly fits the following application scenarios:

• Sinotruk Sitrak C7H — Long-haul logistics trucks operating on intercity highways where cabin comfort directly affects driver performance over extended shifts.
• Sinotruk Sitrak C5H — Medium-to-heavy distribution trucks frequently used in warm climate regions across Africa, the Middle East, and Central Asia.
• Sinotruk Sitrak G7 — Next-generation heavy-duty tractors used in mining, construction material transport, and bulk goods haulage.

In these operating environments, ambient temperatures often exceed 40°C. Therefore, a fully functional air conditioning system is not a luxury — it is a safety necessity. Replacing a failing AC assy promptly helps prevent heat-related driver fatigue and keeps delivery schedules intact.

Customer Case: Fleet Operator in East Africa

Earlier this year, a fleet procurement manager based in Tanzania reached out to us with an urgent request. His company operates 45 Sinotruk Sitrak C7H trucks on long-haul routes between Dar es Salaam and Dodoma. During the hot season, seven trucks experienced AC failures within the same month — and his local suppliers had no stock of the AC Assy 711W61900-7130.

After finding Mettlead through a Google search, he submitted an inquiry and received a quotation within 12 hours. We confirmed stock availability, arranged neutral packaging as requested, and shipped ten units via air freight. The entire process — from first contact to delivery at his warehouse — took just nine days.

His feedback was straightforward: “The fitment was perfect, the price was 30% lower than what we paid from a middleman before, and the cooling performance is identical to the original unit.” Since then, he has placed three additional orders for other Sitrak heavy-duty parts, including radiator assemblies and cab door components.

This is exactly the kind of partnership we build at Mettlead — practical, reliable, and focused on keeping your trucks on the road.

Frequently Asked Questions About AC Assy 711W61900-7130

Is the 711W61900-7130 AC Assy an original Sinotruk part or aftermarket?

This AC assembly is manufactured to OEM-equivalent specifications. It matches the original Sinotruk Sitrak part dimensions, electrical ratings, and refrigerant capacity. In other words, it installs and performs identically to the factory-fitted unit, but at a more competitive price point.

Can I use this AC Assy with refrigerant other than R134a?

We strongly recommend using R134a refrigerant only, as the expansion valve calibration and sealing materials are designed specifically for this type. Using alternative refrigerants may void warranty coverage and could damage internal components over time.

How do I know if my AC problem requires a full assembly replacement?

If your Sitrak truck shows multiple symptoms simultaneously — such as weak airflow, warm air output, unusual blower noise, and visible corrosion on the evaporator — replacing the complete AC Assy 711W61900-7130 is often more economical than repairing individual subcomponents. Additionally, a full assembly replacement ensures all internal parts work together as designed.

What is the expected lifespan of this AC assembly under normal use?

Under standard operating conditions and with regular maintenance (including timely cabin filter changes and proper refrigerant levels), this assembly typically delivers 3 to 5 years of reliable service. Trucks operating in extremely dusty environments may benefit from more frequent evaporator cleaning.

Does the 711W61900-7130 come pre-charged with refrigerant?

No. The AC assembly ships dry, without refrigerant charge. Your installation technician will need to evacuate the system, check for leaks, and charge with the correct amount of R134a according to Sinotruk’s service specifications.

Can I order a single unit, or is there a minimum order quantity?

We accommodate both sample orders and bulk purchases. If you need just one unit for testing or an urgent repair, we can arrange that. For volume pricing, contact our sales team with your required quantity for a tailored quotation.
