FAQs:
  • What is the function of the thermostat in the cooling system?
    The thermostat controls the coolant circulation path using a wax mechanism that expands and contracts with temperature, directing coolant through small loops for quick engine warm-up or large loops through the radiator for heat dissipation.
  • At what temperature does the TAMA thermostat open?
    The thermostat valve opens when the coolant temperature rises to approximately 80°C, allowing coolant to flow through the radiator for effective cooling.
  • How does the company ensure product quality for this thermostat?
    We use high-quality raw materials to ensure wear and corrosion resistance, providing durable and reliable performance in the cooling system.
