Details on the 1 Row Plastic Tank Aluminum Core Product Line
The CSF 1 Row Plastic Tank Aluminum Core line combines OEM-style plastic tanks with a robust aluminum core to deliver effective heat dissipation and corrosion resistance. This design supports consistent engine temperatures and is engineered to meet the specifications of Mercedes-Benz ML and R-Class models. The plastic tanks reduce weight while maintaining durability, and the aluminum core ensures efficient thermal conductivity.
Technical Description and Features
This radiator features a cross flow design, allowing coolant to move horizontally through the core, which enhances heat exchange efficiency. The core thickness of 1 5/8 inches and two-row configuration provide a balance between cooling capacity and compact size. Both inlet and outlet diameters measure 1 11/16 inches, positioned on the left and right sides respectively, facilitating straightforward hose connections. The radiator’s dimensions and materials are optimized for the Mercedes-Benz ML320, ML350, ML500, ML550, R320, R350, and R500 models, ensuring compatibility and performance.
Common Applications and Problem Solving
- Replacement for leaking or damaged radiators in Mercedes-Benz ML and R-Class vehicles
- Addresses overheating issues caused by inefficient or clogged radiator cores
- Restores proper coolant flow with OEM-style inlet and outlet sizes
- Improves engine temperature regulation for vehicles experiencing frequent heat spikes
- Suitable for vehicles requiring a radiator with plastic tanks and aluminum core construction
Installation Notes and Tips
When installing the CSF 3458 radiator, ensure all hose connections match the 1 11/16 inch inlet and outlet diameters. Verify the cross flow orientation aligns with the vehicle’s cooling system layout. Since the radiator does not include a cap, reuse the existing cap or source a compatible replacement. Properly bleed the cooling system after installation to prevent air pockets and ensure optimal performance.
