Description

Overview:

  • Genuine Japanese Quality: Denso Silicone Oil is a premium-grade, high-viscosity fluid manufactured to strict original equipment (OE) specifications to restore the precise mechanical function of your vehicle’s cooling system.
  • Engineered for Viscous Clutches: Specifically formulated to serve as the critical power-transfer medium inside thermal fan clutch assemblies, ensuring dependable fan engagement and disengagement.
  • Convenient Single-Use Size: The compact 10ml tube format (Part Number: 046964-0010) delivers a precise, measured volume perfect for servicing individual radiator, engine, or air conditioning cooling fan hubs.

Key Highlights:

  • Precision Viscoelastic Performance: Features advanced polydimethylsiloxane fluid properties that adapt flawlessly to heat, acting with high shear resistance to safely lock the fan clutch when the engine runs hot.
  • Overheating Prevention: Restores factory-spec cooling fan speeds, effectively pulling maximum airflow through the radiator core to halt low-speed or heavy-load engine overheating.
  • High Thermal Stability: Formulated to withstand extreme under-hood operating temperatures without thinning out, thinning down, or breaking down chemically over long service periods.
  • Material Compatibility: 100% chemically inert and non-corrosive, ensuring it will not degrade, pit, or damage internal metal bearings, plastic rotors, aluminum housings, or synthetic rubber seals.

Vehicle Applications:

  • Viscous Fan Hub Restorations: Perfectly suited for servicing and refilling rebuildable viscous fan clutches found in older passenger cars, SUVs, and heavy-duty diesel pickup trucks.
  • Multi-Brand Application: While manufactured by Denso, this high-grade silicone oil is universally trusted for repairing fan hubs on Toyota, Nissan, Mitsubishi, and various European utility platforms.
  • Cost-Effective Repair: Provides an affordable maintenance alternative, allowing mechanics and DIY enthusiasts to successfully rebuild a slipping fan hub rather than replacing the entire mechanical unit.
  • Application Warning: Ensure the internal housing is thoroughly cleaned of old, contaminated fluid before injecting the fresh silicone oil; check vehicle service manuals for the exact required fluid capacity.
