Product Overview
The VHSZ92034277 EGR Water Hose is a specialized coolant line that carries engine coolant to and from the EGR cooler. The EGR cooler’s function is to lower the temperature of recirculated exhaust gases before they re-enter the engine intake. This hose is subjected to high temperatures from both the hot engine coolant and its proximity to the exhaust system. Our replacement hose is manufactured to meet exact OEM specifications for length, inner diameter, and hose-end fitting shape, ensuring a perfect, leak-free connection between the engine block/water pump and the EGR cooler assembly. It is constructed from multi-layer, reinforced rubber designed to withstand constant heat, pressure, and coolant additives.
Key Features & Benefits
-
Direct OEM Fit & Compatibility: A perfect, no-modification replacement for part number VHSZ92034277, guaranteeing correct routing, secure clamp fitment, and leak-free seals at both ends for your Kobelco excavator’s EGR system.
-
Prevents Coolant Loss & Overheating: A secure hose prevents coolant leaks, which can lead to low coolant levels, engine overheating, and potential damage to the EGR valve or cooler due to dry operation.
-
Ensures Proper EGR System Function: Consistent coolant flow is essential for the EGR cooler to effectively reduce exhaust gas temperature. This maintains proper emissions control, prevents intake overheating, and helps avoid related diagnostic trouble codes (DTCs).
-
Heat & Coolant Resistant Construction: Made from high-quality, reinforced rubber (often with fabric or wire reinforcement) that is specifically formulated to resist degradation from hot engine coolant, ethylene glycol, and underhood temperatures.
-
Easy Installation: Designed as a direct swap for the old, failed hose. Installation typically involves draining some coolant, loosening hose clamps, and fitting the new VHSZ92034277 hose with new clamps for best results.
-
Cost-Effective Preventative Maintenance: Replacing a worn hose proactively is a minor expense that prevents the major inconvenience and cost of an overheated engine on the job site and potential EGR system repairs.

Frequently Asked Questions (FAQ)
Q1: What are the symptoms of a failing EGR water hose (VHSZ92034277)?
A: Signs include:
-
Visible coolant leaks in the area of the EGR cooler or along the hose’s path.
-
Low coolant level in the reservoir without other obvious leaks.
-
Sweet smell of coolant from the engine bay, especially when hot.
-
Engine overheating.
-
White steam/smoke from the engine compartment (coolant dripping onto hot exhaust).
Q2: Should I replace the hose clamps when installing this new hose?
A: YES, it is highly recommended. Always use new, high-quality constant-tension or worm-drive clamps. Reusing old, fatigued clamps is a common cause of premature leaks, even with a new hose.
Q3: Can I install this hose myself?
A: Yes, for someone with basic mechanical skills. Important: The cooling system must be partially drained below the level of the hose connections to prevent a large spill. Work on a cold engine to avoid burns from hot coolant. Ensure the new hose is routed correctly without kinks and the clamps are positioned and tightened securely.
Q4: Does a leaking EGR hose affect engine performance?
A: Indirectly, yes. A significant leak can cause engine overheating, which will lead to power loss and potential damage. A small leak may trigger a low coolant warning. If coolant enters the EGR passages, it can cause corrosion or carbon buildup issues over time.
Q5: Is this a genuine Kobelco OEM part?
A: This is a high-quality, OEM-compatible replacement hose manufactured to the exact specifications of the original VHSZ92034277 part, ensuring the same fit, durability, and performance.
