ISUZU EGR Cooler 4HK1 TIER 3 (fits JCB, Hitachi, Case) - 8973789393
High-quality EGR exhaust gas cooler designed for construction machinery equipped with the reliable ISUZU 4HK1 engine (TIER 3 emission standard). It is responsible for cooling exhaust gases before they are reintroduced into the combustion chamber, effectively lowering the engine operating temperature and reducing the emission of harmful nitrogen oxides (NOx). It ensures optimal performance and durability in tracked and wheeled excavators of leading brands.
Technical Specification:
- Part type: Exhaust gas recirculation (EGR) cooler.
- Engine compatibility: ISUZU 4HK1 (TIER 3).
- Application: Exhaust system and emission reduction system.

Workshop Tip: Over time, the EGR cooler becomes contaminated with carbon deposits, which can lead to a drop in power, smoking, or engine overheating (often due to a cracked core and coolant loss). When replacing the cooler, absolutely check the condition of the EGR valve (clean it if necessary) and use new metal gaskets. This will protect the system from hot exhaust gas blow-by. After installation, check the coolant level and quality, and ensure the system is properly bled.
