Aluminum Core Radiator with 38mm Inlet and Outlet & Brazed Cooling Fins for Toyota Hiace 2009-2014

The Radiator Assembly with OEM reference number 16400-75471 is a verified direct-fit replacement for the Toyota Hiace fourth generation (H200 series), specifically designed for petrol engine variants produced between 2005 and 2014. This radiator is a critical component of the engine cooling system, responsible for dissipating heat from the engine coolant to maintain optimal operating temperatures.

Primary Applications (Toyota Hiace):

Engine Compatibility:

• Toyota Petrol engines (including 2.7 VVTi and similar variants)
• Compatible with TRH2, KDH2, and related H200 series chassis

Common Failure Symptoms:

• Engine overheating — temperature gauge rising above normal, especially under load
• Coolant leaks — visible puddles under the vehicle or low coolant levels
• Clogged or damaged core — reduced cooling efficiency due to debris, corrosion, or physical damage
• Cracked plastic end tanks — common failure point on aging radiators (2005-2014 models)
• Cooling fan running constantly — may indicate reduced radiator efficiency

Installation Guidelines (Reference Toyota workshop manual for complete steps):

1. Safety first — allow engine to cool completely before starting work
2. Drain the cooling system — capture coolant for proper disposal
3. Remove the cooling fan assembly and fan shroud
4. Disconnect upper and lower radiator hoses
5. Remove the radiator mounting bolts and brackets
6. Carefully remove the old radiator from the vehicle
7. Compare the new radiator with the old unit — verify core dimensions, hose connection positions (38mm inlet/outlet), and mounting points match
8. Install the new radiator into position
9. Reconnect all hoses and electrical connections
10. Torque mounting bolts to manufacturer specification
11. Refill cooling system with the correct Toyota-approved coolant (50/50 mixture)
12. Bleed the cooling system to remove air pockets — critical for proper cooling
13. Start engine, bring to operating temperature, and check for leaks
14. Verify heater operation and proper temperature gauge reading

Maintenance Schedule:

• Inspect radiator and hoses for leaks or damage during every service
• Flush and replace coolant every 2 years or 40,000 km (or per manufacturer recommendation)
• Clean radiator fins of debris (bugs, dirt, leaves) annually or as needed
• Replace radiator cap if it shows signs of wear or fails to hold pressure

Pro Tips:

• Always use the correct Toyota-approved coolant (color and specification)
• Never mix different coolant types — this can cause chemical reactions and radiator damage
• When replacing the radiator, inspect all coolant hoses for swelling, cracking, or soft spots — replace if necessary

• Individually sealed in protective packaging
• Packed in foam-lined carton (branded or plain)
• Bulk wholesale available in master cartons
• Suitable for: Toyota specialist repair shops, commercial vehicle maintenance depots, auto parts distributors
