FAQ

Q1: How can I be sure this thermostat (8-97300787-3) will fit my excavator?
A: First, confirm that your excavator is powered by an Isuzu 4HK1 engine. Then, locate the thermostat on your engine and check its part number. If it matches 8-97300787-3 or 8973007873, then this is the correct replacement. If you are unsure, please contact us with your machine’s model and serial number for verification.

Q2: Is professional installation recommended for this thermostat?
A: While replacing a thermostat is a relatively straightforward task for an experienced mechanic, we recommend having it installed by a qualified technician. Proper installation ensures the thermostat housing is sealed correctly to prevent coolant leaks and that the system is bled of air. Video technical support is available to guide your technician if needed.

Q3: What routine maintenance is recommended for the cooling system?
A: It is good practice to replace the thermostat whenever the coolant is drained and replaced, typically every 2-3 years or as specified in your equipment’s maintenance manual. Always use the correct type and mixture of coolant. Regularly inspect the radiator cap and hoses for wear and replace them as necessary to ensure the entire cooling system operates efficiently.
