Detailed Description

OSC designs this radiator to match original equipment form and function for the Nissan Sentra. The unit uses premium aluminum construction with cadmium-plated tubes inside and out to help resist premature failure, while the die-cut gasket supports a leak-resistant seal. The integrated transmission oil cooler is built into the radiator assembly, and the unit is engineered for multi-fit applications without changing the look or fit of the vehicle. Part number 1178 is a practical OE-style replacement for Sentra cooling system service.

This part cross-references LIQUI MOLY (e.g., 2038) for the same application.

Common Problems This Radiator Can Address

• Overheating caused by a restricted or aging radiator core
• Coolant leaks from cracked tanks, worn seals, or weakened joints
• Poor heat rejection from a clogged or inefficient cooling assembly
• Transmission fluid temperature concerns related to a failing cooler circuit
• Fitment issues from a damaged or non-OE-style replacement radiator

Installation Notes and Tips

Fits 1991-2000 Nissan Sentra, N/A. Verify inlet and outlet sizing, header dimensions, and cooler line connection points before installation. Inspect hoses, clamps, and mounting points for wear, and flush the cooling system if contamination or debris is present. Part number 1178 is supplied as a direct-fit radiator assembly for OE-style replacement work.

Quality Assurance

OSC tests the transmission and engine oil coolers before assembly, checks the radiator core prior to final build, and tests the completed unit again after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
