The Multiquip 0500408140 Water Pipe Bolt DCA-45USJ 4JG1 is a genuine OEM bolt designed for the DCA-45USJ ultra-silent diesel generator. Sourced directly through Multiquip's authorized parts program, this bolt is the exact component specified for the cooling system water pipe connection on the 4JG1 engine. If you're servicing a DCA-45USJ and need a like-for-like replacement, this is the correct part.
Key Features
- Genuine OEM Specification — Manufactured to the same material grade and thread specification as the original bolt used on the DCA-45USJ production line.
- Cooling System Integrity — Correctly torqued and properly sized to maintain a secure, leak-free connection at the water pipe junction on the 4JG1 engine.
- Direct Fitment for DCA-45USJ — Engineered specifically for the DCA-45USJ ultra-silent generator; installs in the existing water pipe mounting position without modification.
- Prevents Coolant Leaks — A worn, stripped, or missing water pipe bolt can allow coolant to escape, causing engine overheating and unplanned generator downtime.
- Engine-Specific Design — Part description references the Isuzu 4JG1 engine fitted to the DCA-45USJ, confirming application accuracy for technicians ordering by engine model.
The water pipe bolt secures the coolant water pipe to the engine block or associated housing on the Isuzu 4JG1 engine. It plays a critical role in maintaining a pressurized, sealed cooling circuit — without it properly in place, coolant can leak from the connection point, causing the engine temperature to rise and potentially triggering a shutdown or causing lasting damage. Replacing a damaged or missing bolt with the correct OEM fastener ensures the water pipe stays seated under operating pressure and that the cooling system functions as intended.
