RADIATOR HOSE SET TOYOTA 3Y (VIN-00955)

The Radiator Hose Set (Upper + Lower) for the Toyota 3Y engine is a complete coolant transfer hose assembly designed to ensure efficient circulation of engine coolant between the radiator, engine, and water pump. Engineered to OEM specifications, this hose set provides robust performance, heat resistance, and excellent durability — key factors for maintaining stable engine temperature and preventing overheating.

This set includes both the upper and lower radiator hoses, making it ideal for full cooling system maintenance or overhaul.

OEM Part Numbers Included

• Upper Radiator Hose: 16572-71031
• Lower Radiator Hose: 16572-71030

These part numbers correspond directly with Toyota OEM references for radiator cooling hoses used on 3Y engines.

Technical Specifications

Upper Radiator Hose (16572-71031)

• Connects radiator upper outlet to engine thermostat housing
• Engine-specific bends and routing for optimal fitment

Lower Radiator Hose (16572-71030)

• Connects radiator lower outlet to engine water pump inlet
• Designed for smooth coolant flow and reinforcement against pressure

Material & Construction (Both Hoses)

• Material: High-grade, heat-resistant rubber compound
• Reinforcement: Multi-layer synthetic fiber for strength under pressure
• Temperature Resistance: Withstands engine bay heat and coolant chemistry
• Finish: Smooth internal bore to promote constant, unrestricted coolant flow
• Connection: OEM-style bead end profiles for secure hose clamp fit

Vehicle Application

This radiator hose set is suitable for vehicles powered by the Toyota 3Y engine, including but not limited to:

• Toyota HiAce (3Y petrol engine)
• Toyota Qualis / Grand HiAce (3Y petrol variants)
• Toyota LiteAce / TownAce (3Y petrol)
• Toyota Pickup / Hilux (older 3Y petrol versions)
• Other Toyota utility or commercial vehicles using the 3Y engine and associated cooling layout

Exact fitment depends on year and local configuration. Always confirm OEM part number and engine code before installation.

Function & Benefits

• Efficient Coolant Flow: Ensures proper circulation of coolant through the engine and radiator
• Temperature Regulation: Helps maintain optimal engine operating temperature
• Heat & Vibration Resistance: Withstands thermal expansion and engine movement
• OEM-Matched Fit: Direct replacement for Toyota 3Y cooling system hoses
• Full Set Convenience: Includes both upper and lower hoses for complete cooling circuit service

Replacement Recommendation

Radiator hoses should be replaced as part of routine cooling system maintenance or when any of the following issues are present:

• Cracks, bulges, or soft spots along the hose body
• Coolant leakage at hose ends or clamps
• Hose ageing or chemical degradation
• When servicing water pump, thermostat, or radiator

Replacing both upper and lower hoses together ensures balanced coolant flow and long-term reliability.
