Product Features

• Structure: A wax-element type thermostat with a precision-machined metal housing and a heat-sensitive wax core. It features a spring-loaded valve and a seal ring for leak-free operation, calibrated to open at approximately 76°C.

• Performance: Precisely regulates coolant flow to maintain the engine’s optimal operating temperature. The wax core expands and contracts with temperature changes to open/close the valve, ensuring fast warm-up and stable thermal management.

• Design: Directly interchangeable with the original equipment thermostat, ensuring a perfect fit with the thermostat housing and cooling system.

Core Function

1. Temperature Regulation: Controls the flow of coolant between the engine and radiator, ensuring the engine reaches and maintains its optimal operating temperature.

2. Fast Warm-Up: Remains closed during engine startup to allow rapid warm-up, reducing wear and improving fuel efficiency.

3. Overheat Protection: Opens fully at high temperatures to direct maximum coolant flow to the radiator, preventing engine overheating.

Thermostat D22-102-06+D SHANGCHAI – OEM-Grade Engine Cooling Control for Heavy-Duty Applications

When your fleet depends on SHANGCHAI-powered trucks and machinery, every component in the cooling system must perform without compromise. The Thermostat D22-102-06+D SHANGCHAI is precision-engineered to regulate coolant flow with exacting accuracy, protecting your engine from thermal stress, premature wear, and costly downtime. Sourced directly from METTLEAD Truck Parts at factory-direct pricing, this thermostat delivers OEM-equivalent reliability to fleet operators, workshop managers, and procurement professionals across the globe.

Key Features and Benefits of Thermostat D22-102-06+D

Precision Thermal Regulation

This thermostat opens at a calibrated temperature range (typically 71°C–83°C depending on application spec), ensuring the SHANGCHAI diesel engine reaches its optimal operating temperature quickly while preventing overheating under heavy loads. Faster warm-up means reduced fuel consumption during cold starts by up to 8–12%.

OEM-Matching Build Quality

Manufactured with a high-grade copper-sensing element and corrosion-resistant brass housing, the D22-102-06+D delivers the same dimensional accuracy and thermal response curve as the original factory part. It drops right into your SHANGCHAI engine block without modification.

Extended Engine Life

By maintaining consistent coolant temperature within the design envelope, this thermostat reduces thermal cycling stress on cylinder liners, head gaskets, and piston rings. Stable thermal management can extend major overhaul intervals by 15–20% compared to operating with a failed or stuck thermostat.

Robust Durability

The wax-pellet actuating mechanism is rated for over 100,000 thermal cycles, ensuring dependable performance across the full service life of the engine between maintenance intervals.

Application Scenarios – Where Thermostat D22-102-06+D SHANGCHAI Performs

The D22-102-06+D thermostat is purpose-built for SHANGCHAI diesel engines commonly found across a wide range of Chinese heavy-duty vehicles and industrial equipment:

• SHACMAN F2000/F3000 Dump Trucks – Equipped with SHANGCHAI SC9D engines for mining and construction haulage in extreme ambient temperatures.
• XCMG & LIUGONG Wheel Loaders – Running SHANGCHAI D6114 or C6121 powerplants under continuous high-torque loading cycles.
• SANY Concrete Mixers and Pump Trucks – Where stop-and-go urban operation demands rapid thermal stabilization to avoid overheating.
• FOTON AUMAN Heavy Cargo Trucks – Long-haul logistics routes across Africa, Southeast Asia, and the Middle East where ambient temperatures exceed 45°C.
• Power Generator Sets (Gensets) – Stationary SHANGCHAI-powered generators operating at constant RPM require precise coolant control to maintain output efficiency.

In each of these scenarios, a malfunctioning thermostat can lead to engine overheating within minutes or chronic under-temperature operation that accelerates soot buildup and oil dilution. The D22-102-06+D prevents both failure modes.

Frequently Asked Questions – Thermostat D22-102-06+D SHANGCHAI

What symptoms indicate the D22-102-06+D thermostat needs replacement?

A failing thermostat typically causes one of two problems: the engine overheats rapidly because the thermostat is stuck closed (blocking coolant flow to the radiator), or it never reaches operating temperature because the thermostat is stuck open. Look for high coolant temperature warnings, poor cabin heater output, increased fuel consumption, or white exhaust smoke during warm-up as clear indicators.

Is the D22-102-06+D thermostat a direct fit replacement for the original SHANGCHAI part?

Yes. The D22-102-06+D is manufactured to OEM dimensional and thermal specifications. It installs directly into the thermostat housing on SHANGCHAI D6114, SC9D, and C6121 engine series without any adapters, gasket modifications, or ECU recalibration.

What is the recommended replacement interval for this thermostat?

Under normal operating conditions, we recommend inspecting the thermostat every 40,000–60,000 km or during each major coolant service. If the engine has experienced chronic overheating events or coolant contamination, replace it immediately regardless of mileage.

Can I test the thermostat before installation?

Absolutely. Suspend the thermostat in a container of water and gradually heat it with a thermometer present. You should observe the valve begin opening at approximately 71°C and reach full-open stroke (≥ 8.5 mm) by 83°C. If it fails to open or opens at an incorrect temperature, it should not be installed.

Does the Thermostat D22-102-06+D SHANGCHAI come with a sealing gasket?

The thermostat includes an integrated rubber seal. However, depending on your engine’s thermostat housing condition, we recommend inspecting and replacing the housing O-ring or paper gasket separately to ensure a leak-free installation.

What coolant types are compatible with this thermostat?

The D22-102-06+D is compatible with all standard ethylene glycol and propylene glycol-based coolants, including long-life OAT (Organic Acid Technology) formulations. Avoid mixing coolant types, as silicate gel deposits can impair thermostat valve movement over time.
