Detailed Description

This One Stop Solutions radiator is engineered around original equipment dimensions and cooling requirements, making it a strong match for OE-style radiator replacement work. The unit uses premium-grade aluminum construction in the cooling assembly, cadmium-plated tubes, and a die-cut gasket to support leak resistance and long-term durability. The integrated transmission cooler is a concentric type, and the radiator is assembled and tested to factory specifications for fit and performance. Part number 1277 is also referenced by APDI 8011277 and Standard Ignition 2059 for the same application.

For shoppers searching for a radiator for Honda Civic or a replacement radiator for Acura Integra, this part number 1277 offers a direct-fit cooling solution with the correct downflow layout and cooler configuration. It is built for vehicles that require a radiator with an integrated transmission oil cooler and OE-style mounting and connection points.

Common Problems This Radiator Addresses

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission fluid temperature issues in radiator-equipped cooling systems
• Corrosion-related radiator failure in high-mileage vehicles
• Poor fitment after using an incorrect replacement radiator

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and cooler layout before installation. This radiator uses a downflow configuration with 1 1/4 in. inlet and outlet connections, so matching the original vehicle setup is important for proper installation. Inspect hoses, clamps, and surrounding cooling system components before fitting the new unit to reduce the chance of repeat service.

Because this radiator includes a transmission oil cooler, confirm that the cooler line routing matches the original application before final assembly. For Honda Civic and Acura Integra applications, compare the original radiator layout to Part Number 1277 to ensure the correct OE-style replacement is selected.

Quality Assurance

OSC states that each radiator is tested multiple times during production, including cooler testing before tank installation, core testing before assembly, and a final assembled-unit test. The design also incorporates engineering updates aimed at addressing original failure points and improving service life in higher-mileage vehicles.
