Compatibility and Vehicle Applications

The NRF 35381 Condenser is specifically engineered for a range of Toyota models, ensuring seamless integration with existing HVAC architectures.

• Toyota RAV4 II (A2) – 2000‑2005: Compatible with 1.8 L and 2.0 L engine variants (1ZZ-FE, 1AZ-FSE/FE).
• Toyota Rav 4 2 (Klimakondensator + Trockner): Includes integrated dryer for extended system protection.
• Nissens 94741 Radiator Replacement: The NRF 35381 serves as an OEM replacement for the Nissens 94741 condenser, maintaining identical mounting points and airflow characteristics.
• Other Toyota SUVs and Sedans: Models such as the Corolla, Camry, and Prius (where applicable) feature compatible HVAC layouts that accept the NRF 35381 with minor adjustments.

Installation Guide

Installing the NRF 35381 Condenser requires adherence to safety protocols and precise alignment of mounting hardware. The following steps outline a typical installation procedure:

1. Preparation: Disconnect the vehicle battery, drain existing refrigerant (if replacing), and remove the old condenser by loosening mounting bolts.
2. Mounting: Position the NRF 35381 in the designated cavity. Align the mounting brackets with OEM holes and secure using supplied fasteners.
3. Electrical Connections: Attach the high‑voltage wiring harness, ensuring correct polarity and secure crimp connections.
4. Refrigerant Charging: Evacuate the HVAC system to remove air and moisture. Recharge with the specified refrigerant (R134a or R1234yf) according to manufacturer guidelines.
5. Testing: Reconnect the battery, start the engine, and verify proper cooling performance. Check for leaks using a pressure gauge and visual inspection.

Maintenance Tips

• Inspect fins regularly for debris or damage; clean with a soft brush or compressed air.
• Verify the integrity of the integrated dryer (if present) by monitoring moisture levels during operation.
• Ensure that all mounting bolts remain tight and free from corrosion.
• Perform periodic pressure tests to confirm system seal integrity.

Benefits Over Competitors

• Superior Thermal Performance: The aluminium alloy construction delivers higher heat transfer rates compared to steel counterparts.
• Reduced Weight: Lighter design contributes to overall vehicle efficiency and fuel economy.
• Durability: Anodised finish resists corrosion, extending service life even in harsh climates.
• Ease of Installation: Standard OEM mounting points eliminate the need for custom adapters or extensive modifications.
