If you’re keeping a 90s or early 2000s Cadillac with the 4.6L V8 on the road, this radiator from HDRadiatorPlaza is a solid replacement.

It fits the Allante, DeVille, Eldorado, and Seville—basically the FWD Caddy platforms.
It’s a 1-row aluminum core, which cools better than the old copper ones and weighs less.

Dimensions are 14 7/8 inches long, 30 1/2 inches tall, and 1 1/4 inches wide.

Inlet’s 1 5/16 inch, outlet’s 1 9/16 inch, and it uses quick-connect style mounting—though hardware’s not included, so reuse your old stuff.

No EOC (engine oil cooler) built in, so if your car has a separate cooler, you’re fine.

It’s 100% leak tested and durability tested before shipping.

Brand new, unpainted aluminum, so it looks clean in the engine bay.

Part number LR2517 crosses with OE.
Comes with a warranty, and it’s made for a direct fit—no universal cutting.
If your Caddy’s overheating or the plastic tanks on the old rad cracked, swap this in and get back to cruising.
Also comes with a Prop 65 warning, but honestly, what doesn’t these days.
Solid build, good price.
