One Stop Solutions 1851 Radiator

OE-Style Radiator for Volvo Cooling Service

This OSC Premium radiator is built for direct replacement service on select Volvo applications, including 1993-1996 Volvo 850, 1997 Volvo 850 with transmission oil cooler, 1998-2000 Volvo S70, and 1998-2000 Volvo V70 without vent tube. Part number 1851 is engineered around OES form and function with a crossflow design and integrated transmission oil cooler.

Key Features

• Premium aluminum core construction with plastic tanks
• Crossflow radiator design for OE-style fitment
• Transmission oil cooler included; engine oil cooler not included
• Cadmium-plated tubes inside and out to resist premature failure
• Die-cut gasket design for leak resistance
• Individually pressure tested during production
• Core dimensions: 23 1/8 in. height, 15 1/4 in. width, 1-1/4 in. thickness
• Inlet diameter 1 7/16 in.; outlet diameter 1 1/2 in.

Detailed Description

OSC part number 1851 is a replacement radiator designed for Volvo 850, S70, and V70 cooling system service where an OE-style radiator is required. The unit uses a single-row aluminum core with plastic tanks and a plated transmission cooler section to maintain factory-style cooling performance. Core and header dimensions are engineered for drop-in fitment, and the radiator is built with fitted components torqued to factory specifications for consistent assembly quality. This part cross-references APDI 8011851 and Spectra Premium CU1851 for the same application.

What It Helps Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission temperature concerns tied to a failing cooler circuit
• Fitment issues from a damaged or non-OE-style replacement radiator
• Cooling system service on high-mileage Volvo 850, S70, or V70 vehicles

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizes, and transmission cooler connection spacing before installation. This radiator is a crossflow design and is intended for the listed Volvo applications only. Confirm whether your vehicle requires the 1997 Volvo 850 with transmission oil cooler or the 1998-2000 Volvo V70 without vent tube configuration before ordering. Replace worn hoses, clamps, and coolant as part of the repair, and bleed the system carefully after installation.

Quality Assurance

OSC tests the transmission and engine oil cooler circuits before tank installation, checks the core before assembly, and tests the completed radiator again after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
