OEM-grade Aluminum Core Radiator with Brazed Cooling Fins for Toyota Vitz Yaris 2005 Manual Transmission

The Radiator Assembly with OEM reference number 16400-21270 is a verified direct-fit replacement for the Toyota Vitz (XP90) / Yaris second generation (2005-2007), specifically designed for vehicles equipped with the 1NZ-FE 1.5L or 2NZ-FE 1.3L petrol engines. This radiator is a critical component of the engine cooling system, responsible for dissipating heat from the engine coolant to maintain optimal operating temperatures.

Manufactured to meet or exceed original equipment standards, this radiator features a brazed aluminum core with plastic end tanks, delivering reliable heat dissipation and long service life under demanding operating conditions. It is designed for manual transmission (MT) vehicles and is compatible with both with and without air conditioning configurations.

Common Failure Symptoms:

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 (available separately: 16711-21110, 16361-21100)
4. Disconnect upper and lower radiator hoses (16571-21120, 16572-21090)
5. Disconnect transmission cooler lines (if equipped with automatic transmission — note this is for MT vehicles)
6. Remove the radiator mounting bolts and brackets
7. Carefully remove the old radiator from the vehicle
8. Compare the new radiator with the old unit — verify core dimensions, hose connection positions, and mounting points match
9. Install the new radiator into position
10. Reconnect all hoses, lines, and electrical connections
11. Torque mounting bolts to manufacturer specification
12. Refill cooling system with the correct Toyota-approved coolant (50/50 mixture)
13. Bleed the cooling system to remove air pockets — critical for proper cooling
14. Start engine, bring to operating temperature, and check for leaks
15. 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
• For MT vehicles, ensure the radiator is the correct specification for manual transmission

• 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, independent garages, auto parts distributors
