One Stop Solutions HD9146 Radiator

Heavy-Duty Radiator for OE-Style Cooling

The One Stop Solutions HD9146 is a heavy-duty radiator built to match original equipment fit, form, and function. It is engineered for direct replacement service and uses a plastic aluminum core construction with a single-row design for dependable heat transfer in demanding cooling systems.

Compatible With vehicle applications that use a 31-7/16 in. core height, 23-5/16 in. core width, and 1-1/4 in. core thickness, this radiator also features 2 in. inlet and outlet diameters and a CSX4 header style with 4-crimp strips over the tabs. The HD9146 is a practical choice for radiator replacement on heavy-duty cooling setups where OE-style dimensions matter.

Detailed Description

OSC Automotive Products designs the HD9146 radiator to provide OE-style replacement performance with drop-in fit, form, and function. Production testing includes cycle, vibration, burst, and environmental evaluation to help verify durability during manufacturing. The radiator uses a plastic aluminum core and a stainless steel top outlet cooler material designation, supporting a construction approach commonly used in heavy-duty cooling applications. For buyers searching for a radiator for Honda Civic or similar vehicle-specific cooling service, the HD9146 should be matched by dimensions and connection size before installation.

This part cross-references 41-2460 and 5800-09ST for the same application. The HD9146 part number is also useful when comparing replacement options for radiator service on Honda Civic and other OE-matched cooling applications.

Common Problems This Radiator Can Address

• Coolant leaks from a damaged or aging radiator core
• Overheating caused by restricted heat transfer
• Cracked plastic end tanks or weakened seams
• Cooling system performance loss from corrosion or internal wear
• Replacement needs after impact damage or long-term mileage use

Installation Notes and Tips

Verify core height, core width, thickness, inlet diameter, and outlet diameter against the original radiator before ordering. Confirm header style and connection layout match the vehicle’s cooling system routing. Flush the cooling system, inspect hoses and clamps, and check the fan, thermostat, and coolant condition during replacement. For fitment-based searches, compare the HD9146 to the original radiator used in Honda Civic applications and other vehicles with the same dimensional requirements.

Quality Assurance

OSC Automotive Products states that its radiators undergo multiple production tests, including cycle, vibration, burst, and environmental testing, to help confirm OE-level performance targets. The brand also emphasizes quality control and research-driven product development for heat transfer components.
