CSF 3761 Radiator

CSF 3761 Radiator Overview

The CSF 3761 radiator is an OE-style replacement built with an aluminum core and plastic tanks for select Kia applications. It is engineered as a cross-flow radiator with a single-row core and a high-efficiency plate-type oil cooler, making it a direct-fit cooling component for the listed vehicles.

Compatible With 2017-2019 Kia Soul, 2014-2018 Kia Forte5, and 2014-2016 Kia Forte Koup. This radiator is identified by part number 3761 and is designed around OEM-style tank construction with a quick-connect outlet pipe.

Key Features

• Aluminum core with plastic tanks for OE-style construction
• Cross-flow design with 1-row core layout
• Core thickness: 1 1/4 in.
• Inlet diameter: 1 3/8 left; outlet diameter: 1 3/8 right
• Integrated high-efficiency plate-type oil cooler
• No radiator cap included
• Quick-connect outlet pipe for factory-style connection
• Part number 3761 for easy identification

Detailed Description

CSF manufactures radiators to high-performance standards and validates cooling performance through laboratory wind-tunnel testing. The 3761 radiator follows that engineering approach with a 15 5/16 in. core width, 18 1/4 in. core length, and 1 1/4 in. core thickness for the specified Kia Soul, Kia Forte5, and Kia Forte Koup applications. The design uses an aluminum core paired with plastic tanks to match OE-style packaging and fitment requirements.

This radiator is a practical replacement for drivers searching for a 2017-2019 Kia Soul radiator, a 2014-2018 Kia Forte5 radiator, or a 2014-2016 Kia Forte Koup radiator. It also cross-references Bosch 13523 for the same application.

What It Helps Address

• Overheating caused by a leaking or restricted radiator
• Coolant loss from cracked tanks or aged core materials
• Reduced heat transfer from a worn factory radiator
• Transmission or engine cooling concerns tied to radiator wear
• Fitment issues when replacing an OE-style Kia radiator

Installation Notes

Verify inlet and outlet orientation before installation: inlet is left and outlet is right. This unit uses a cross-flow layout, includes a quick-connect outlet pipe, and does not include a cap. Confirm vehicle application by year, make, and model before ordering, especially for 2017-2019 Kia Soul, 2014-2018 Kia Forte5, and 2014-2016 Kia Forte Koup.

Quality Assurance

CSF states that its factories are ISO/TSO certified and that its radiators are engineered and tested for cooling performance validation. The brand has supplied radiators worldwide for more than 50 years and manufactures a broad range of applications across major vehicle lines.
