LS and LT Radiator for 1991-1996 Chevy Impala/Caprice and Buick Roadmaster
When you bring an LS or LT powerplant into a 1991 to 1996 Impala Caprice or Buick Roadmaster with a manual transmission, the 1991-1996 Impala Radiator (Manual Trans) is engineered to manage coolant temperature under sustained highway speeds and heavy towing without requiring modifications to chassis or shroud. It installs directly into the OEM mounting points and aligns precisely with factory brackets and fluid lines to eliminate trimming work and speed up installation time. Featuring a fully TIG welded aluminum core and tanks, the assembly rejects heat effectively and resists corrosion to preserve structural integrity. With this LS and LT compatibility design, coolant temperatures remain stable during extended drives and spirited runs, giving you confidence in demanding conditions.
Leak Free Strength from TIG Welded Aluminum
This radiator is constructed using full TIG welds at every joint, ensuring uniform wall thickness and eliminating leak paths between core seams and tank joints. TIG welding controls heat input precisely during fabrication, preventing distortion and preserving the designed flow geometry. The result is a single piece assembly capable of withstanding high coolant pressure and vibration without fatigue or seam separation. Built with American craftsmanship, this feature delivers a reliable structure that lasts through repeated heat cycles and heavy duty use.
Advanced Aluminum Core Promoting Rapid Cooling
Crafted entirely from high grade aluminum, the core maximizes heat transfer from engine coolant to external air. Aluminum's thermal conductivity outperforms traditional materials, allowing the radiator to reject heat quickly under sustained highway speeds or towing. A carefully engineered fin density and tube arrangement aid in distributing coolant evenly, preventing hotspots and maintaining consistent operating temperatures. This design ensures that coolant remains within optimal range during spirited runs, reducing the risk of overheating.
Durable Bare and Black Epoxy Finishes
The radiator is available in classic bare aluminum for maximum radiant heat transfer and authentic appearance or in a black epoxy finish that provides a robust barrier against moisture and road contaminants. The bare surface allows natural anodization over time, preserving thermal performance and delivering a timeless look. Alternatively, the epoxy coating seals the aluminum, resisting corrosion from salt, dirt, and chemicals often encountered on winter roads. Both finishes are applied with precision to coverage critical areas and maintain the radiator's structural integrity.
Exact Fit for LS and LT Manual Transmission Installations
Engineered for a seamless drop in to 1991 through 1996 Chevy Impala, Caprice and Buick Roadmaster models with manual transmissions, this unit aligns exactly with factory mounting points and fluid connections. By matching OEM bracket locations and hose fittings, installation time is reduced and frustration from fitment issues is eliminated. There is no need for chassis modifications, trimming of shroud or adapter plates, so the radiator can be secured and plumbed with basic hand tools. This direct fit approach supports quick engine swaps and preserves the vehicle’s original serviceability.
