Overview – EGR COOLER CORE 4955926DC
4955926DC is the EGR cooler core used on CUMMINS ISX engines to cool recirculated exhaust gas before it re-enters the intake system. We can supply this EGR cooler core as well as related CUMMINS emissions system parts, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
The cooler core is built to the original tube and fin arrangement, with the stainless steel tubes, end plates and mounting brackets matched to the CUMMINS ISX EGR circuit. The coolant passages and gas passages are sized to the original flow so the engine maintains the correct intake temperature and emission levels. The core is pressure tested to withstand the coolant and exhaust service conditions. As an OEM-spec core, it bolts into the original cooler housing without modification.
Applicable Models & Applications
This EGR cooler core is used on CUMMINS ISX engines where the exhaust gas recirculation system cools the re-circulated gas before the intake manifold. Typical applications include on-highway and industrial ISX builds with the EGR cooling circuit. Confirm the tube layout, flange pattern and coolant connection arrangement against the core removed from your engine before ordering.
Maintenance & Replacement
A leaking or blocked EGR cooler core shows up as coolant loss, white exhaust, overheating, fault codes and reduced power. Inspect the core for cracks, corroded tubes and blocked gas passages during regular service. When replacing, drain the coolant, remove the old core, clean the mounting faces and fit the new core with fresh gaskets to the original torque. Refill with the correct coolant and check the cooling system for leaks.
Price Reference (USD)
The reference price for this EGR COOLER CORE (4955926DC) is approximately USD 120 – 520 per unit depending on grade, quantity and shipping destination. This is a planning estimate only – confirm current pricing and availability with our sales team before ordering.
Value & Service
A blocked EGR cooler can push the engine into derate, so we verify 4955926DC against the original CUMMINS ISX tube and flange layout before dispatch. We supply the core together with the gaskets and coolant hose package in one tracked order. Our team will confirm the correct core for your engine serial number and emissions configuration before you buy.
