FAQ

Q1: How do I verify that this thermostat fits my excavator engine?
A: Check the part number stamped on your existing thermostat. It should match 1-13770070-0 or 1137700700. Also confirm your engine model (6BD1, 6BG1, 6BB1, or 4BG1) by checking the engine nameplate. This thermostat is designed for Hitachi Ex200-5 and Ex200 series machines, but always cross-reference with your equipment manual.

Q2: What is the recommended installation procedure for this thermostat?
A: Installation should be performed by a qualified technician. Drain the coolant, remove the thermostat housing, clean the mating surfaces, install the new thermostat with the jiggle valve positioned correctly, replace the gasket, and refill with fresh coolant. Torque the housing bolts to manufacturer specifications to prevent leaks.

Q3: How often should the thermostat be replaced in excavator engines?
A: As a general guideline, replace the thermostat every 2-3 years or 2,000-3,000 operating hours, whichever comes first. However, if you notice engine overheating, slow warm-up, or fluctuating temperature readings, inspect and replace the thermostat immediately. Regular replacement prevents unexpected failures that can cause costly engine damage.
