Product Details

TYC 161 is engineered as a radiator replacement for many 1966-1990 GM platforms, including Chevrolet Caprice, Impala, Monte Carlo, El Camino, C10, K10, and Blazer, along with Buick LeSabre, Riviera, Regal, and Skylark, plus Oldsmobile 98, Delta 88, Cutlass, and Toronado. It also covers select Cadillac DeVille, Eldorado, Seville, and Fleetwood applications, as well as Pontiac Bonneville, Catalina, LeMans, Grand Prix, and Parisienne models. The integrated transmission cooler uses adapter-style 5/8-18 UNF connections and supports vehicles originally equipped with a transmission oil cooler in the radiator.

This part cross-references APDI 8010161 and Spectra Premium CU161 for the same application. TYC Radiator 161 is a practical OE-style replacement for owners searching for a radiator for Chevrolet Caprice with TOC, Buick LeSabre radiator replacement, or Oldsmobile Delta 88 cooling system service.

Common Problems This Radiator Can Address

• Coolant leaks from an aging or corroded radiator core
• Overheating caused by restricted tubes or reduced heat transfer
• Transmission temperature concerns when the original cooler is damaged
• Cracked or deteriorated hose connection points
• Cooling system service on high-mileage classic GM vehicles

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and transmission cooler line connections before installation. This radiator uses hose clamp inlet and outlet connections and is intended for applications that match the listed fitment and TOC configuration. Flush the cooling system, inspect hoses and clamps, and confirm fan shroud and mounting clearance during replacement. For vehicles such as Chevrolet Caprice, Buick Riviera, and Oldsmobile 98, compare the original radiator layout to ensure the crossflow design and cooler fittings match the factory setup.

Quality Assurance

TYC manufactures replacement cooling components for OE-style fitment and application matching. Part number 161 is built to the listed specifications for direct replacement use in supported Buick, Chevrolet, Cadillac, Oldsmobile, Pontiac, and GMC vehicles.
