OEM Aluminum Radiator with Brazed Cooling Fins and 3.5 Bar Pressure Resistance

The Radiator Assembly with OEM reference number 16400-47090 is a verified direct-fit replacement for the Toyota Yaris / Vitz third generation (2010-2017), specifically designed for vehicles equipped with the 1NR-FE, 1NZ-FE, and 2NZ-FE 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 with a high-performance aluminum core featuring brazed cooling fins and plastic end tanks, this radiator delivers reliable heat dissipation with 25% higher thermal efficiency than standard copper alternatives. It is built to withstand demanding driving conditions, with a pressure resistance rating of 3.5 bar (ISO 14063 certified).

Primary Appliions (Toyota / Subaru):

Engine Compatibility:

• Toyota 1NR-FE (1.33L, 4-cylinder, petrol) - 63-73 kW
• Toyota 1NZ-FE (1.5L, 4-cylinder, petrol) - 106 hp
• Toyota 2NZ-FE (1.3L, 4-cylinder, petrol) - 86 hp
• Toyota 1NR-FKE (1.33L, petrol) - 1NR-FE variant

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 (2010-2017 models)
• Cooling fan running constantly - may indie 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. Disconnect transmission cooler lines (if equipped)
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 (350 x 477 x 16mm), 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 specifiion
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 specifiion)
• 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
• Inspect radiator drain cock and O-rings during installation

• 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
