Frequently Asked Questions
Q: What engines and forklift models is the MD972905 thermostat compatible with?
A: The MD972905 is designed for Mitsubishi 4G series engines (4G33, 4G52, 4G54, 4G63, 4G64) and fits Mitsubishi FG10, FG15, FG18, FG20, FG25, FG30, FG35, FGC10, FGC15, FGC18, FGC20, FGC25, and FGC30 electric lift trucks. Verify your exact engine and forklift model before ordering.
Q: At what temperature does the MD972905 thermostat open?
A: The MD972905 is engineered to open at 82 degrees Celsius (180 degrees Fahrenheit). This temperature range is correct for Mitsubishi 4G series engines in material handling applications. Operation outside this range indicates thermostat failure.
Q: What are the materials used in the MD972905 construction?
A: The MD972905 features brass and stainless steel construction with a high-density composite fiber gasket. This combination resists corrosion and thermal cycling typical in forklift engine cooling systems. The gasket provides a durable, reliable seal for repeated thermal cycling.
Q: How long does the MD972905 thermostat typically last before replacement?
A: Thermostat lifespan depends on engine operating conditions and coolant maintenance. In typical forklift service, expect 3 to 5 years or 1500 to 2500 operating hours. Signs of failure include engine overheating, coolant leaks around the gasket, or poor temperature regulation.
Q: Does the MD972905 include the gasket?
A: Yes, the MD972905 includes the high-density composite fiber gasket. The gasket is engineered for direct fitment on Mitsubishi 4G series engines. No additional gasket purchase is required.
Q: Are there alternative part numbers for the MD972905 thermostat?
A: No cross-reference part numbers are documented for the MD972905. Use the exact OEM part number MD972905 when ordering to ensure correct fitment for Mitsubishi 4G series engines and FG/FGC forklift models.
