FAQ
Q: How do I verify this thermostat fits my Isuzu 6WG1 engine? A: Check the existing part number on your current thermostat. It should match one of these numbers: 1-13770080-1, 1-13770-089-1, or 8-98271161-0. Also verify your engine model number (6WG1 or 170F) on the engine data plate. If you have a different number, please contact us with your engine serial number and equipment model for cross-reference assistance.
Q: What is the installation procedure for this thermostat? A: Installation should be performed by a qualified diesel mechanic. General steps include: 1) Drain coolant below thermostat housing level, 2) Remove housing bolts and old gasket, 3) Clean mating surfaces thoroughly, 4) Install new thermostat with jiggle pin at 12 o’clock position, 5) Replace with new gasket, 6) Torque housing bolts to manufacturer specifications (typically 20-25 Nm), 7) Refill coolant and bleed air from system. Always use a new gasket and replace coolant as recommended.
Q: What maintenance is required for this thermostat? A: Check thermostat function annually or every 1,000 operating hours, whichever comes first. Test by suspending thermostat in hot water – it should begin opening at 71°C and be fully open by 82°C. Replace immediately if: engine runs cold (never reaches operating temperature), engine overheats frequently, or if the thermostat sticks open or closed during inspection. Always replace coolant and thermostat together for best results.
