Product Features

• Structure: A wax-element type thermostat, featuring a precision-machined metal housing, a rubber sealing ring, and a wax-filled thermal actuator. The 80°C rating ensures it opens at the optimal engine operating temperature.

• Performance: The wax actuator expands reliably with temperature changes, ensuring precise opening and closing to maintain engine coolant temperature. The rubber seal provides a leak-free fit, and the robust construction resists corrosion and fatigue.

• Design: Directly interchangeable with the original equipment thermostat, ensuring a perfect fit and consistent performance without modifications.

Core Function

• Regulates engine coolant flow to maintain an optimal operating temperature of approximately 80°C, balancing heat dissipation and fuel efficiency.

• Stops coolant flow to the radiator when the engine is cold, allowing it to warm up quickly and reducing wear from cold starts.

• Opens to allow coolant circulation once the engine reaches operating temperature, preventing overheating and ensuring stable performance.

Thermostat Core 80 Degree VG1047060002 SINOTRUK – Precision Engine Temperature Control

Your engine’s cooling system is only as reliable as the thermostat that governs it. The Thermostat Core 80 Degree VG1047060002 is engineered to deliver precise thermal regulation for SINOTRUK heavy-duty diesel engines, opening at exactly 80°C to maintain optimal coolant flow. Built to OEM specifications, this thermostat core eliminates overheating risks, reduces fuel waste from cold-running engines, and extends the service life of your entire cooling system. METTLEAD Truck Parts supplies this critical component at factory-direct pricing with rapid global delivery — keeping your fleet on the road and your maintenance costs under control.

Why This Thermostat Core Matters to Your Engine

A thermostat that opens too early forces your engine to run cold, increasing fuel consumption by up to 10% and accelerating cylinder wear. One that opens too late invites overheating, warped heads, and blown gaskets. The VG1047060002 thermostat core sits at the sweet spot — calibrated to an 80°C opening temperature that matches SINOTRUK’s original engineering parameters.

Key Functions and Benefits

• Precise 80°C Opening Temperature — Maintains the ideal thermal window for combustion efficiency, emission control, and lubricant viscosity across all operating conditions.
• OEM-Grade Wax Element — Uses a high-purity thermal wax pellet that responds consistently to temperature changes, ensuring repeatable valve actuation over thousands of thermal cycles.
• Full Stroke Travel — Achieves complete valve opening to allow unrestricted coolant circulation at operating temperature, preventing hot spots in the cylinder block.
• Corrosion-Resistant Construction — Stainless steel and brass components resist coolant degradation, extending replacement intervals even in harsh water-quality environments.
• Direct Drop-In Fitment — Matches OEM dimensions and mounting geometry, requiring zero modifications during installation.
• Reduced Downtime — Reliable thermal control prevents unplanned stops caused by overheating alarms or limp-mode activation.

Frequently Asked Questions — Thermostat Core VG1047060002

What happens if I install a thermostat with the wrong opening temperature?

Installing a thermostat rated above 80°C delays coolant circulation, causing localized overheating in the cylinder head. A thermostat rated below 80°C keeps the engine running too cool, increasing fuel consumption, carbon buildup, and oil dilution. The VG1047060002 is calibrated specifically for SINOTRUK engines that require an 80°C opening point.

How do I know when this thermostat core needs replacement?

Common symptoms include fluctuating coolant temperature gauge readings, engine taking unusually long to reach operating temperature, heater blowing cold air, or repeated overheating warnings. We recommend proactive replacement every 50,000 km or during major cooling system service.

Is this thermostat core compatible with extended-life coolants (OAT/HOAT)?

Yes. The stainless steel and brass construction resists corrosion from both traditional silicate-based coolants and modern organic acid technology (OAT) formulations. The integrated rubber seal is formulated to withstand all standard heavy-duty coolant chemistries.

Can I test the thermostat core before installation?

Absolutely. Submerge the thermostat in water and heat gradually with a thermometer. The valve should begin opening at 78–82°C and reach full lift by 95°C. If it fails to open within this range, do not install it — contact us for a replacement.

Does this part come with a gasket or housing?

This listing is for the thermostat core element only (VG1047060002). If you need the complete thermostat housing assembly, gasket, or O-ring seal, please inquire — we stock the full range of cooling system components for SINOTRUK engines.

What is the difference between an 80°C and 71°C thermostat for SINOTRUK?

The 80°C thermostat (VG1047060002) is the standard OEM specification for most SINOTRUK highway and general-purpose applications. A 71°C variant is sometimes used in extreme ambient heat environments or specialized cooling configurations. Always verify your engine’s service manual before selecting a thermostat rating.
