A: If your engine takes an unusually long time to reach operating temperature or if the cab heater isn't blowing hot air, the thermostat might be stuck open. While safer than being stuck closed, it reduces fuel efficiency and increases carbon buildup in your cylinders.
A: Our thermostat features an OEM-standard tri-metal structure. This provides the durability required for 24/7 mining or construction operations. It is currently trusted by repair shops and equipment fleets worldwide for its stable performance under extreme loads.
A: Generic parts often use inferior spring materials that lose tension over time. This leads to improper temperature regulation, causing the engine to run too hot, which degrades high-pressure fuel injectors and oil quality.
