The Multiquip V949656 Coolant Temp Sensor O-Ring is a genuine OEM sealing component designed for the DCA400SSV diesel-powered generator. As a direct OEM replacement, this O-ring is produced to the same material and dimensional standards as the original part, ensuring a proper fit around the coolant temperature sensor port. Verified for the DCA400SSV, this part ships as an exact match — no guesswork on fitment when you order by part number V949656.
Key Features
- OEM-Grade Sealing Material — Manufactured to the original compound and durometer specification, maintaining compression and resistance to coolant chemistry over repeated thermal cycles.
- Drop-In Sensor Port Fit — Sized to seat correctly in the DCA400SSV coolant temperature sensor bore, reinstalling the same way the original did with no trimming or shimming.
- Confirmed Fitment for DCA400SSV — Verified against the DCA400SSV parts schema so you can order with confidence for this generator platform.
- Leak-Free Coolant System Integrity — A correctly seated O-ring prevents coolant seepage at the sensor port, keeping the cooling circuit at operating pressure and protecting the engine from overheating events.
- Fuel and Coolant Fluid Resistance — Compound selected for compatibility with engine coolant, resisting swelling or degradation that would cause premature seal failure.
The coolant temperature sensor O-ring forms a pressure-tight seal between the sensor body and the engine block or coolant passage, preventing coolant from escaping around the sensor thread or bore. Without an intact seal, even a minor seep at this point can lead to coolant loss, inaccurate temperature readings, or engine protection system faults. On a generator like the DCA400SSV — where continuous runtime and thermal stability are critical — a failed or flattened O-ring at this location should be replaced promptly to maintain cooling system integrity and accurate sensor operation.
