8-97211209-0 / 8-94382546-0 Isuzu 4JG1 4JG2 Engine Thermostat (82℃ / 76.5℃)
This product is a dedicated thermostat for the Isuzu 4JG1 and 4JG2 series diesel engines, available in two part numbers: 8-97211209-0 and 8-94382546-0. The thermostat is a critical temperature control component in the engine cooling system, regulating coolant flow to maintain optimal engine operating temperature. It is offered in two opening temperature specifications — 82℃ and 76.5℃ — to suit different climate conditions and operating requirements. It is widely used in construction machinery and generator sets powered by 4JG1/4JG2 engines.
Dual Temperature Options – Available in 82℃ (recommended for cold/temperate regions) and 76.5℃ (standard type) to meet diverse climate and application needs.
OEM Specification – Manufactured to strict Isuzu OE standards for direct replacement without any modification.
High-Quality Material – Made of heat-resistant alloy components with a corrosion-resistant spring system, ensuring reliable operation even under heavy-duty, continuous-load conditions.
Precise Temperature Control – Accurate opening and closing temperature regulation ensures the engine reaches optimal operating temperature quickly, preventing overheating or overcooling.
Improved Fuel Economy – Stable temperature control contributes to better fuel efficiency, reduced engine wear, and enhanced overall reliability.

It is recommended to inspect and replace the thermostat gasket/seal ring at the same time when replacing the thermostat.
Clean the thermostat housing mounting surface thoroughly before installation; remove any old sealant residue.
We recommend replacement by a professional technician. Pay attention to the thermostat orientation during installation — ensure the wax pellet faces the engine side.
After replacement, bleed the cooling system to remove trapped air and prevent overheating due to air locks.
A faulty thermostat may cause engine overheating, slow warm-up, unstable temperature, or increased fuel consumption. Replace immediately if any abnormality is detected.
